GaryLeaves are where photosynthesis takes place and stems support leaves, branches, and contain vascular tissue. There are two types of stems - herbaceous stems which are soft and green, and woody stems which are rigid and brown. Roots absorb water and nutrients from the soil. The vascular system of seed plants is made up of xylem, phloem, and cambium. Gymnosperms are vascular plants that produce seeds not protected by fruit, and conifers are gymnosperms that produce male and female cones. Angiosperms are vascular plants that flower and produce fruits containing seeds.

Angiosperms 2016
This document discusses the characteristics of vascular plants, specifically angiosperms. It describes that angiosperms have enclosed seeds protected inside a fruit. They have flowers, vascular tissue, and alternate between generations. Angiosperms are divided into monocots and dicots. Monocots have one cotyledon and parallel veins, while dicots have two cotyledons and branching veins. The document outlines the structures and functions of floral parts and how angiosperms reproduce through a process called double fertilization.
Kingdom plantae 2
Bryophytes are mostly terrestrial plants. They are found in moist shady places. But they need water for fertilization and completion of their life cycle. Hence they are called ‘amphibious plants’.
They include approximately 960 genera and about 25,000 species.
Life cycle of Bryophytes shows sporophytic and gametophytic stages..
Bryophytes have root-like structures called rhizoids. Rhizoids are unicellular in liverworts while multicellular in mosses.
angiosperm reproduction and biotechnology
1) Angiosperm reproduction can occur sexually through flowers producing seeds or asexually through vegetative reproduction.
2) Flowers contain reproductive structures like stamens which produce pollen and carpels containing ovules. Pollen grains contain male gametophytes while ovules contain female gametophytes.
3) Fertilization occurs through double fertilization - one sperm fuses with the egg to form a zygote and another with polar nuclei to form endosperm, providing nutrition for the developing embryo.

- The document discusses plant structure and function, including plant morphology, anatomy, growth, reproduction, transport, nutrition, and responses to stimuli.
- Plant structures are adapted for and reflect their functions, with roots specialized for absorption and shoots for photosynthesis, reproduction, and gas exchange.
- Plants use a variety of reproductive strategies including cross-pollination to increase genetic diversity, and produce fruits and seeds adapted for dispersal.
Angiosperms
The document provides information about the reproductive biology of flowering plants (angiosperms). It discusses key events in angiosperm evolution such as the origin of flowers and fruits. It also summarizes the characteristics and life cycles of monocots and eudicots. Angiosperms have had a profound influence on the evolution of other organisms through symbiotic relationships like pollination and seed dispersal. Their success is largely due to adaptations like seeds that enabled colonization of new environments.
Lab 6 - Angiosperms
This document summarizes key events in the evolution of angiosperms over 400 million years and discusses their anatomy and relationships to pollinators. It describes the unique characteristics of angiosperms such as enclosed ovules and immotile sperm. While the origin of angiosperms is controversial, the oldest known fossils date to around 125 million years ago in the early Cretaceous period. The document also reviews monocot and dicot distinguishing features and compares their stem, leaf and root anatomies.
Angiosperms and reproduction
This document summarizes key aspects of reproduction in angiosperms. It discusses flower structure, the processes of pollination and fertilization, and conditions required for seed germination. Flowers have evolved to transfer pollen between plants through pollinators like insects, birds and wind. Pollination involves the transfer of pollen grains containing male gametes from the anther to the stigma. Fertilization occurs when the male nuclei from pollen tubes reach the ovule, where the egg cell is located. Seeds then disperse via various mechanisms before germinating under appropriate temperature, oxygen, and water conditions.
Plant Recognition
The document provides an overview of how to identify plants by discussing their key characteristics and categories. It begins by dividing plants into two main categories: flowering or non-flowering. It then discusses gymnosperms, which are non-flowering plants that bear naked seeds, such as conifers. It also discusses angiosperms, which are flowering plants whose seeds are enclosed in fruits. Angiosperms undergo pollination to reproduce. The document also provides information on identifying tree types using leaf characteristics such as whether they are evergreen or deciduous, simple or compound, and vein patterns.

Seed plants characteristics
Seed plants have three main characteristics: 1) they have vascular tissue that transports nutrients and water throughout the plant, 2) they reproduce using seeds, and 3) they have a complex life cycle involving sporophytes and gametophytes. Seeds contain an embryo, stored food, and a protective seed coat. The embryo develops into a new plant, the stored food nourishes the embryo's growth, and the seed coat protects these parts. Leaves capture sunlight for photosynthesis, stems transport nutrients and provide structure/support, and roots anchor the plant and absorb water and nutrients.

Angiosperm and Gymnosperm
Angiosperms are seed-producing flowering plants whose seeds are enclosed within an ovary, while gymnosperms are seed-producing non-flowering plants whose seeds are unenclosed. Angiosperms have seasonal life cycles, produce seeds inside fruits, and reproduce sexually through flowers. In contrast, gymnosperms are evergreen, produce bare seeds on scales, leaves, or cones, and reproduce through unisexual cones. While both are seed-producing plants, angiosperms and gymnosperms differ in their reproductive structures, seed and pollen distribution, and wood properties.
Angiosperms
Angiosperms are the most diverse group of flowering seed-producing land plants. They have key characteristics including ovules enclosed in a carpel structure made of an ovary and stigma, double fertilization leading to endosperm formation, stamens with two pairs of pollen sacs, and phloem tissue composed of sieve tubes and companion cells. The parts of an angiosperm include roots that absorb water and nutrients underground, various stem types like stolons and rhizomes, and leaves that can be simple or compound and arranged alternately, opposite, or whorled on the stem. Angiosperms are divided into monocots and dicots based on whether their seeds have one or two coty

Angiosperms are flowering plants that produce seeds enclosed in fruits. They include agricultural crops, garden flowers, trees, shrubs, and weeds. Angiosperms are vitally important as they are the primary food source for humans and animals, providing about 80% of the world's food. They also produce oxygen, lumber, fibers, perfumes, spices, and are the basis for many drugs. Due to their importance as a food source and in producing oxygen, angiosperms are essential for survival of humans and the ecosystem.
Seed Plants Lab
Seed plants can be divided into gymnosperms and angiosperms. Gymnosperms produce naked seeds without fruit and include conifers like pine and spruce trees. Angiosperms are flowering plants that produce seeds within a protective fruit. They reproduce through double fertilization where one sperm cell fertilizes the egg to form the embryo while another fertilizes the endosperm. Angiosperms are divided into monocots and eudicots depending on whether they have one or two seed leaves. Key parts of flowering plants include stamens, carpels, ovaries, and fruits which aid in seed protection and dispersal.

8 6. Structure and function of plant organs
This document summarizes the structure and function of various plant organs including roots, stems, leaves, flowers, fruits, and seeds. It describes that roots have fibrous or tap structures and function to absorb water and minerals. Stems transport water and nutrients and provide structure. Leaves carry out photosynthesis using chloroplasts and stomata. Flowers are reproductive organs that produce fruits containing seeds, which can grow into new plants.
Gymnosperms
Gymnosperms are seed plants that reproduce through cones and do not have flowers. They have woody stems and needles or scales instead of broad leaves. Their adaptations for life on land include woody growth for support, needles with less surface area for photosynthesis and water retention, and seeds that enclose embryos with stored food for greater survival. Their life cycle involves heterosporous male and female cones that produce pollen and ovules, with fertilization occurring through pollen tubes leading to the formation of seeds containing a sporophyte embryo.
cbse Asexual reproduction by chitran mandal
This document summarizes several methods of plant reproduction, including both sexual and asexual reproduction. It describes vegetative propagation through tubers, bulbs, and runners, providing examples like potatoes, daffodils, and strawberries. It also discusses other asexual propagation techniques like cuttings, layering, and grafting, explaining how new plants can be produced through pieces of the parent plant. Artificial propagation allows for quick reproduction of genetically identical plants and the adaptation of plant varieties for desired traits.
Plant divisions gymnosperms and angiosperms
This document summarizes the key characteristics and divisions of vascular seed plants. It describes the two main groups, gymnosperms and angiosperms. Gymnosperms produce naked seeds on cone scales, lack flowers, and have needle-like or scale-like leaves. They are divided into four groups including conifers. Angiosperms enclose seeds in an ovary that develops into a fruit. They are characterized by flowers and are divided into monocots and dicots.
angiosperms
Seeds are mature fertilized ovules that contain dormant young plants. They are composed of an embryo, stored food reserves, and a seed coat. Seeds play an important role in plant reproduction and dispersal. They vary widely in size, structure, and longevity. The document discusses the components, development, importance, and diversity of structures in angiosperm seeds. It covers topics like seed size, viability, food reserves, seed coats, vivipary, and the use of seeds as food.
Plants corr
Plants are multicellular organisms that carry out photosynthesis. Photosynthesis takes place in chloroplasts and uses chlorophyll, carbon dioxide, water, and sunlight to produce organic matter. Plants undergo respiration to obtain energy and carry out vital functions. Plants are classified based on whether they have vascular tissue and whether they flower and produce seeds. Xylem transports water and nutrients while phloem transports organic matter. Gymnosperms are seed-producing plants like conifers that do not produce fruits, while angiosperms are flowering plants that produce fruits and seeds enclosed within flowers.
Plant Structure and Function
The document discusses the structures and functions of plant roots, stems, and leaves. It explains that plants have either taproots or fibrous roots, and that roots absorb water and minerals. The stem transports water and nutrients throughout the plant and has nodes, buds, and vascular bundles. Leaves undergo photosynthesis to produce sugars for the plant.
Classification plant-converted
It discuss about plant classification in detail. Introduction about plants classification, the contributions of botanist, Plants Classified based on form. Hierarchy-Taxonomic Groups, plant classification with the images and explanations
Angiosperms and gymnosperms
There are two main types of seed plants - gymnosperms and angiosperms. Gymnosperms reproduce using cones instead of flowers and include cycads, ginkgos, conifers, and gnetophytes. Angiosperms are the largest group of plants and reproduce using flowers containing sepals, petals, stamens, and a pistil. Pollination occurs when pollen from the stamen sticks to the stigma on the pistil, and fertilization happens when the pollen joins with an ovule in the ovary. Seeds then develop inside the ovary and are dispersed in different ways depending on the plant.
Reproduction
REPRODUCTION
Reproduction is the capacity of all living things to give rise to new living things. It includes the transmission of hereditary material from the parent/parents.
The two types of reproduction are:
Asexual Reproduction
Sexual Reproduction
ASEXUAL REPRODUCTION
Is the simplest form of reproduction. Occurs in plants, animals, bacteria, and protists Requires one parent. Is more reliable than sexual reproduction. Doesn’t allow for any type of genetic variation.

Cloning
What is cloning?
Cloning is the creation of an organism that is an exact genetic copy of another. This means that every single bit of DNA is the same between the two!
How does one go about making an exact genetic copy of an organism? There are a couple of ways to do this: artificial embryo twinning and somatic cell nuclear transfer.
NEW STANDARDS 6th grade Plants1: classification & processes
The document provides an overview of plant classification and processes. It divides plants into two main categories: nonvascular and vascular plants. Nonvascular plants include mosses and lichens. Vascular plants are further divided into seedless plants like ferns and seed plants like gymnosperms and angiosperms. It describes the characteristics and examples of these different types of plants. The document also covers plant structures, functions, and processes like photosynthesis, transpiration, and the plant life cycle.
Sect 9.2
The document summarizes key concepts about the sun-earth-moon system:
1) The moon rotates on its axis at the same rate that it revolves around Earth, so the same side always faces Earth.
2) It takes the moon 29.5 days to rotate on its axis and revolve around Earth.
3) The moon's most obvious effect on Earth is ocean tides.
4) The document defines new and full moons and the phases of the moon. Eclipses occur when the sun or moon are blocked by Earth or the moon.
Sect 14.3
1) The document discusses key concepts in ecology including producers, consumers, food chains, and symbiotic relationships.
2) Producers such as plants use photosynthesis to obtain energy from the sun, while some use chemosynthesis, and consumers obtain energy by eating producers or other consumers.
3) Symbiotic relationships include mutualism, commensalism, and parasitism, and an organism's niche describes how it finds resources and avoids threats in its environment.

Sect 9.2
The document summarizes key concepts about the sun-earth-moon system:
1) The moon rotates on its axis at the same rate that it revolves around Earth, so the same side always faces Earth.
2) It takes the moon 29.5 days to rotate on its axis and revolve around Earth.
3) The moon's most obvious effect on Earth is ocean tides.
4) The document defines new and full moons and the phases of the moon. Eclipses occur when the sun or moon are blocked by Earth or the moon.
Sect 14.3
1) The document discusses key concepts in ecology including producers, consumers, food chains, and symbiotic relationships.
2) Producers such as plants use photosynthesis to obtain energy from the sun, while some use chemosynthesis, and consumers obtain energy by eating producers or other consumers.
3) Symbiotic relationships include mutualism, commensalism, and parasitism, and an organism's niche describes how it finds resources and avoids threats in its environment.
Sect 10.2
Mercury is hot and cold with a surface of many craters and cliffs. Venus is similar in size and mass to Earth but has a constant extremely high temperature. Mars has polar ice caps, possible ancient water channels, and the largest volcano, while Earth has one moon, water, atmosphere and is the only known place with life.
Sect 19.1
Sound waves are compressional waves that travel through air, creating areas of higher and lower density called compressions and rarefactions. The frequency of a sound wave is the number of compressions and rarefactions that pass by per second, while the wavelength is the distance between compressions or rarefactions. Sound travels fastest in solids and slowest in gases. Louder sounds have greater amplitude and carry more energy than softer sounds with smaller amplitude.

Sect 19.2
1. Music is sound that is deliberately produced in regular patterns, while noise lacks patterns.
2. All objects can vibrate at natural frequencies, and musical instruments produce sound through vibrations of strings, air columns, or resonating chambers that amplify the sounds.
3. The human ear collects sound through the outer ear, amplifies it in the middle ear, and changes it to nerve impulses in the inner ear to enable hearing.
Sect 13.1
This document summarizes key abiotic (non-living) environmental factors including air, water, soil, sunlight, temperature, elevation, and climate. It explains that air contains nitrogen, oxygen, argon and carbon dioxide. Water and soil are important for plant and animal life. Sunlight drives photosynthesis. Temperature affects what organisms can survive. Elevation impacts temperature, and climate refers to average weather conditions over time including these factors. Soil is both abiotic and biotic as it is formed from non-living materials but contains remains of dead organisms. Changes in trees and plant life at higher elevations may be due to factors like decreasing temperature with increasing elevation.
Sect 9.1
The document summarizes key concepts about the Earth's relationship to the sun and moon from a 6th grade science textbook. It discusses how ancient Greeks like Aristotle were able to determine the Earth was spherical by observing shadows on the moon. It also explains the Earth's axis of rotation, its tilted axis causing seasons, and defines solstices and equinoxes as the days when the sun is furthest or directly overhead at the equator.
Sect 13.2
The document summarizes key concepts about the water cycle, carbon cycle, and nitrogen cycle. It explains that the water cycle involves evaporation from bodies of water into the atmosphere, condensation of water vapor back into liquid water, and precipitation falling back to bodies of water. It also notes that human water usage can impact the amount of water available to evaporate. It describes how carbon and nitrogen cycle through the biosphere, atmosphere, soil and organisms, and how plants and animals rely on these elements to survive through photosynthesis and cellular processes.
Sect 17.2
Heat energy is always produced during an energy transformation. Energy cannot be created or destroyed, only changed from one form to another. Almost 90% of electricity in the USA is produced from fossil fuels and nuclear power by transforming the chemical energy in these fuels into kinetic energy of steam to spin turbines and generate electrical energy.
Sect 18.3
1. A heat engine converts thermal energy into mechanical energy through various processes. Common heat engines include steam engines and internal combustion engines.
2. Internal combustion engines burn fuel inside the engine, which heats the air and causes it to expand quickly, transferring energy to move the pistons. Common types are diesel, 2-stroke, and 4-stroke engines.
3. Refrigerators and air conditioners work similarly by absorbing heat inside and releasing it outside using a coolant. The coolant absorbs heat inside, is compressed to release heat outside, then cools and repeats the cycle.
Sect 18.2
Heat is the transfer of thermal energy between objects due to a temperature difference. Heat always flows from warmer objects to cooler ones. There are three main ways heat is transferred: conduction, convection, and radiation. Conduction involves direct contact between objects, convection involves the movement of heated matter like air or water, and radiation transfers heat through electromagnetic waves even without direct contact. Thermal insulators like foam, feathers, and fur are poor conductors that slow the transfer of heat, while metals are good conductors that allow easy transfer of heat.
Sect 14.1&2
An ecosystem consists of all the organisms living in an area along with the physical components of the environment. A population is a group of the same species that lives in the same ecosystem, while a community includes all the populations in an ecosystem. Limiting factors like food and water usually have the greatest effect on population size by restricting its growth and determining the ecosystem's carrying capacity, which is the maximum population it can sustain.

Sect 10.1
Galileo and Copernicus observed that the Sun, not Earth, is at the center of the solar system. The Sun contains over 99% of the mass in the solar system and its huge gravity keeps the planets in orbit around it. Johannes Kepler discovered that planets move in ellipses, not perfect circles, around the Sun and that planets closer to the Sun move faster than those farther away.
Sect 11.2
Seedless nonvascular plants like mosses and liverworts lack vascular tissues and reproduce via spores. They were the first plants to colonize new environments and helped form soil. Seedless vascular plants such as ferns and horsetails have vascular tissues and can grow taller. Ancient seedless plant fossils provide evidence these plants formed coal deposits, which are now mined and burned to generate electricity.

plants
This document provides an overview of plant characteristics and classification. It discusses the key parts and processes of seed plants including angiosperms and gymnosperms. Seed plants are classified into gymnosperms, which produce naked seeds, and angiosperms, which produce seeds within fruits. Angiosperms undergo pollination and fertilization to produce seeds which are then dispersed by fruits. This allows for sexual reproduction through cross-pollination and asexual reproduction through vegetative propagation. Seed plants are essential to humans and ecosystems.

Solution
1. Pine is a conifer plant which belongs in the Pinus genus of the family Pinaceae. They are
gymnosperms, yellow in colour with harder wood and two to three needles per fascicle. They are
evergreen with about 10-260 feet tall in height. Needles are green and bundled in clusters called
fascicles.When the shoot is damaged then the needle fascicles will generate bud to replace the
lost leaves. Pine trees uses photosynthesis to create or obtain their own nourishment.
Photosynthesis is the process where sunlight, water and carbon dioxide are taken by the pine tree
and then converted into sugars and starches which are used as food energy. They have thick bark
to protect against cold. Pine cones protect the seeds during harsh winter. The needles reduce the
water loss. Pine trees reproduce by producing seeds. They possess both male and female
reproductive structures on the same tree. Pollen is produced by male cone and is transferred with
the help of pollination to the female cone and results in the formation of embryos. The embryos
grows into seeds.
2. Aloe vera is a plant which belongs to the genus Aloe. It is cultivated for various medicinal and
agricultural use. They are stemless plant of about 60-100 cm tall in height. The leaves are thick
and fleshy and grown in trophical climates. The leaves of aloe vera contain phytochemicals. Aloe
vera forms mycorrhiza which is a symbiosis that allows the plant access to mineral nutrients in
soil.They have succulents which helps the plant to retain water. Aloe vera has thich and fleshy
leaves which enlarges for the accomodation of aqueous tissue. The leaf cuticle is covered with
wax. Aloe vera is an autotrophic organism which makes its own food through
photosynthsis.Aloe vera is a vascular plant which has phloem and xylem cells that helps in the
movement of water and food as per required. Aloe vera plants produce offsets adjacent to the
parent plants and also produce tall seeded flower spikes. Pollination also helps in the production
of seed. The offsets can be separated and grown separately.
3. Spiders have eight legs and fangs that inject venom. They belongs to Arachnids class. They
feed on dead arthropods. pollen if caught in webs are also eaten. They capture their prey by the

Root anatomy
There are two main types of root systems: taproot systems and fibrous root systems. A taproot system features a primary taproot that grows downward deep into the soil, with many smaller secondary roots branching out from it. A fibrous root system lacks a dominant taproot and instead comprises many similar-sized primary and secondary roots that spread close to the soil surface. Roots have several key functions: to absorb water and minerals, anchor the plant, and store food produced by the leaves. The root tip contains cells called the apical meristem where new cells are produced, and is protected by the root cap. [END SUMMARY]
Introduction To Plants
Plants have evolved several key adaptations for living on land, including the ability to absorb nutrients from soil, prevent water loss through structures like the cuticle and stomata, and reproduce without water using pollen. Vascular plants have tissues that transport water and developed seeds, flowers, and other structures that make reproduction more efficient. Plants are divided into nonvascular plants like mosses and vascular plants including seedless forms like ferns and seed plants like gymnosperms and angiosperms. Angiosperms are further divided into monocots and dicots.

Conifers include some of the most important forest trees and cycads have existed for over 225 million years. Ginkgo biloba is the only living species of ginkgophytes. Angiosperms are the largest group of plants and have flowers and fruits containing their seeds.
Chapter 9-Plants
Plants range in size from microscopic to huge redwood trees. They vary in where they grow from polar regions to hot deserts. Plant cells contain structures like cell walls, chloroplasts, and a vacuole that distinguish them from animal and bacterial cells. Plants are believed to have evolved from green algae in the sea around 420 million years ago. They adapted to land through structures like a waxy cuticle and the development of seeds for reproduction on land. Plants are classified as vascular or nonvascular, with vascular plants having transport tissues.

project in science
Nonvascular plants lack true roots, stems, and leaves due to the absence of vascular tissue. They are called thallophytes and include mosses, liverworts, and hornworts. They must live in moist environments because they lack internal structures for transporting water and nutrients and generally only grow 1-2 cm tall. Vascular plants have specialized tissues for transport and include both spore-bearing plants like ferns and seed-bearing plants like gymnosperms and angiosperms. Gymnosperms produce naked seeds enclosed in cones while angiosperms produce seeds enclosed within flowers in an ovary.
Plant Tissues

Test 14 review questions
The document contains a chapter review for a 6th grade science class. It includes 30 multiple choice questions about topics like limiting factors, communities, ecosystems, producers, consumers, decomposers, symbiotic relationships, food chains, and the roles of different organisms. It tests understanding of key concepts around interactions between living and non-living things in an environment.
Sect 18.1
Temperature is a measure of the average kinetic energy of molecules, while thermal energy is the total kinetic and potential energy of all molecules in an object. Temperature scales like Fahrenheit and Celsius assign numbers to temperature, with Celsius used in science. Thermal expansion causes objects to expand when heated as molecules move farther apart. While temperature does not change when mixing substances of the same temperature, thermal energy is the total energy and can increase by mixing. The Kelvin temperature is always larger than Celsius, as it is measured from absolute zero.
Sect 17.3
The document discusses various energy sources including fossil fuels like coal, oil and natural gas which were formed from ancient plants. It also discusses renewable sources like solar, wind, hydroelectric and geothermal energy as well as nuclear energy. Fossil fuels are nonrenewable since they are being used faster than they can be replaced, while solar is considered an inexhaustible source since the sun will provide energy for billions of years. The document provides information on how different energy sources work and their advantages and disadvantages.
Sect 17.1
Energy is the ability to cause change and can take many forms. Kinetic energy is the energy of motion and depends on an object's mass and speed. Potential energy is stored energy due to an object's position or height. Chemical energy is stored in chemical bonds and is released when bonds are broken or formed.
Sect 13.3
1) Producers like plants convert light or chemical energy into food through photosynthesis or chemosynthesis. A food chain shows how matter and energy pass between organisms. A food web shows multiple interconnected food chains in an ecosystem.
2) An energy pyramid displays the available energy at each trophic level. Only about 10% of energy is transferred between levels, so the amount decreases going up the pyramid. This limits the length of food chains.
3) There are more mice than hawks in a grassland because energy transfers inefficiently between trophic levels in food chains, according to the energy pyramid model.
Test 12 review questions
1) The document is a review of chapter 12 from a 6th grade science textbook about plant processes. It contains 30 multiple choice questions about topics like photosynthesis, phototropism, plant hormones, and plant responses.

3) Key topics assessed include phototropism, gravitropism, photoperiodism, the plant hormones auxin, ethylene, gibberellin and their effects, as well as structures involved in photosynthesis like chloroplasts, stomata, and palisade layers.
Sect 12.1
The document summarizes key concepts about plant processes from a 6th grade science textbook. It discusses how leaves take in carbon dioxide and water to produce glucose and oxygen through photosynthesis. The glucose is used as an energy source or stored as excess sugar in plant structures like carrot roots. Respiration breaks down glucose to release energy, with carbon dioxide and water as byproducts. Photosynthesis and respiration are important for plant growth and as the basis of food chains.

Unit 2 test review collins
The document summarizes key concepts in earth science including:
1) Separating plates form when forces inside Earth push plates apart, creating new crust to fill gaps.
2) Upwarped mountains form when forces inside Earth push up the crust.
3) Folded mountains include the Appalachian Mountains which form from folding of crustal rocks.
4) Mantle is the largest layer of Earth, solid but flows like putty.
Sect 10.4
Comets consist of dust, rock, and ice and surround the solar system in the Oort Cloud. Meteoroids are rocks in space that burn up as meteors when entering the Earth's atmosphere, often forming meteor showers when the Earth crosses their orbital paths. Asteroids are rocky bodies similar to planetary materials that occur predominantly between the orbits of Mars and Jupiter.
Sect 10.3
Jupiter is the largest planet in the solar system and has a huge storm called the Great Red Spot that has lasted over 400 years. Saturn is a large gaseous planet like Jupiter that has thousands of rings composed of rock and ice. The chapter discusses the characteristics of Uranus, Neptune, and Pluto, including Uranus having a bluish-green color from methane and a sideways tilted axis, Neptune also being bluish-green with storms, and Pluto being a small ice-rock planet with a moon called Charon that is about half its size.
Review questions ch 9
This document contains 40 multiple choice questions from a 6th grade science chapter reviewing concepts about the sun-earth-moon system. The key points covered include:
- The moon takes 27.3 days to rotate once and revolve around Earth
- Earth is farthest from the sun during summer
- Earth's rotation causes the sun to appear to rise and set
- The different phases of the moon
- Seasons in the northern and southern hemispheres
- Features of the moon like maria and impact basins
- Earth has an elliptical orbit and tilted axis
- Equinoxes and solstices mark the changing of seasons
Sect 9.3
The first lunar surveys were conducted by Soviet Luna probes and American Ranger and Lunar Orbiter spacecraft in the 1960s. The Lunar Orbiter Clementine mapped the lunar surface and found that the lunar crust is thinner on the near side of the moon than the far side. The Lunar Prospector mission discovered that the Moon has a small iron rich core and detected ice water in craters at the lunar poles, estimating up to 3 billion metric tons of water ice may be present.
