The crust is the thinnest layer and is made up of either lighter continental crust or denser oceanic crust. Below the crust lies the thick mantle, which makes up most of the Earth's mass. At the center are the core layers - the liquid outer core surrounding a solid inner core made mostly of iron. Scientists study seismic waves from earthquakes to learn about the composition and structure of the deeper interior layers not directly observable.
Earth Science 4.1 : Inside the Earth
The document summarizes the layers and structure of the Earth's interior. It discusses the three main layers - crust, mantle, and core - based on their chemical compositions. The crust is the outermost layer and thinnest, with continental crust thicker than oceanic crust. The mantle makes up most of the Earth's mass and lies between the crust and core. The core is the central part made mostly of iron. It then describes the physical structure, dividing the interior into lithosphere, asthenosphere, mesosphere, outer core, and inner core based on their properties. Tectonic plates consist of crust and the rigid upper mantle, floating on the asthenosphere. Scientists have mapped the interior using seismic waves from earth
Earth's Layers Presentation
The document discusses the structure and composition of the Earth's interior. It can be summarized as follows:
1) The Earth has three main layers - the crust, mantle, and core. The crust is the outermost layer, the mantle is below the crust, and the core is at the center.
2) The crust and upper mantle make up the rigid lithosphere, while the lower mantle and outer core flow slowly like hot asphalt in the asthenosphere.
3) The inner core is solid iron, surrounded by the liquid outer core, with the mantle in between composed of silicate rock that flows via convection currents.
The Layer of the Earth song and ppt
The Earth is composed of three main layers - the crust, mantle, and core. The crust is the outermost layer and is made up of either dense oceanic crust or less dense continental crust. Below the crust lies the mantle, which makes up the bulk of the Earth's volume. At the center is the core, about 1/3 of the Earth's mass, which is mostly solid iron. The crust and upper mantle form separate tectonic plates that slowly move atop the asthenosphere.
Layers of the Earth - Earth and Life Science
The Earth is composed of three main layers - the crust, mantle, and core. The crust is the outermost layer and is made up of loose rocks and soil. Below the crust lies the mantle, which makes up 66% of the Earth's mass and is composed of molten rock. The core is at the center of the Earth and is made of iron and nickel, with the outer core being liquid and the inner core solid. Each layer has unique physical properties related to temperature, pressure, density and composition that differentiate it from the other layers.

EARTH STRUCTURE AND COMPOSITION
The document describes the structure and composition of the Earth. It discusses the four main layers of the Earth - crust, mantle, outer core, and inner core. The crust is the topmost layer and is broken into tectonic plates that "float" on the mantle. The mantle, which makes up most of the Earth's volume, becomes hotter with increasing depth and drives convection currents that move the plates. The outer core is liquid while the inner core is solid due to extreme heat and pressure at the Earth's center.
Layers of the Earth (Application)
The document is a quiz about the layers of the Earth. It asks questions about which layer we live on (crust), the layer below the crust composed of solid and melted rocks (mantle), the deepest portion of the Earth (core), the boundary between the crust and mantle (Mohorovicic Discontinuity), the topmost solid part (lithosphere), the boundary between the mantle and core (Gutenberg Discontinuity), the hottest layer (inner core), the thickest layer making up 80% of the volume (mantle), and the scientists who study the layers (geologists). It also provides the average temperature of the inner core (5,000°C).

Earth’s Interior Notes (Jenny)
The document summarizes the layers that make up Earth's interior based on studies of seismic waves. It describes the crust as the outermost solid layer ranging from 5-40km thick, with the continental crust composed of granite and oceanic of basalt. Below is the mantle extending nearly 3,000km, consisting of the lithosphere and asthenosphere layers. The inner core, spinning faster than the rest of the planet, generates Earth's magnetic field.
Earth’s structure and materials2
The document defines key terms related to the structure and layers of the Earth, including the crust, mantle, lithosphere, asthenosphere, mesosphere, outer core, and inner core. It explains that the crust is divided into continental crust, composed mainly of granite, and oceanic crust, composed of basalt. It also summarizes that heat from the core is transferred by convection into the mantle, driving convection currents in the mantle and core that have caused tectonic plate movement and generated the Earth's magnetic field for over 4 billion years.
Life cycle of a star
Stars are born from contracting nebulae of gas and dust. They spend most of their lives on the main sequence, fusing hydrogen into helium in their cores. Eventually they run out of fuel in their cores and their outer layers expand, forming red giants or supergiants. From there, smaller stars shed their outer layers to form planetary nebulae and white dwarfs, while larger stars explode as supernovae, leaving behind neutron stars or black holes.
Seasons
1) The Earth's axis is tilted 23.5 degrees, which causes the hemispheres to receive different amounts of sunlight throughout the year, leading to seasons.
2) In summer, the hemisphere tilted toward the Sun receives more direct sunlight and experiences warmer temperatures, while the opposite hemisphere experiences winter.
3) Common misconceptions are that the Earth's distance from the Sun or elliptical orbit cause seasons, but the Earth is actually closest to the Sun in January and farthest in July with little effect on seasons.

Atomic structure fix
An atom is the smallest unit of matter that retains the identity of a substance. Atoms are composed of a nucleus at the center containing protons and neutrons, and electrons that surround the nucleus in an electron cloud. The nucleus contains most of the atom's mass, while the electrons occupy a large volume of space outside the nucleus but have a relatively small mass. Protons and neutrons are compacted in the nucleus giving it a positive charge, while electrons outside the nucleus have a negative charge, making the overall atom electrically neutral.
Foodchains
This document discusses ecosystems, habitats, food chains and webs. It explains how different animals are adapted to their environments and how they fulfill different roles as producers, consumers, herbivores, carnivores, omnivores, predators and prey. The document also addresses how the loss of any part of a food chain or habitat can negatively impact other organisms and discusses the importance of caring for the environment.
Moon phases
The document describes the different phases of the moon as it orbits Earth. It explains that a new moon occurs when the moon is between the sun and Earth so we cannot see it. As the illuminated portion grows it is called a waxing crescent moon, then a quarter moon when half is lit, followed by a waxing gibbous moon until it is fully lit as a full moon. Then the cycle repeats in reverse as it wanes from gibbous to quarter to crescent until a new moon.
Ecosystems
Ecosystems consist of interacting populations of organisms and their biotic and abiotic environment. Organisms rely on biotic factors like other species for food and abiotic factors such as water, temperature, and soil composition. Competition occurs when multiple organisms or populations rely on limited resources within their shared environment and niche.
Tectonic plates
The document discusses plate tectonics and how it relates to various geological phenomena. The Earth's crust is divided into major tectonic plates that move and interact along three types of plate boundaries. Divergent boundaries form new crust through seafloor spreading. Convergent boundaries involve plates colliding through oceanic-continental or continent-continent collision, forming mountain ranges. Transform boundaries involve lateral movement of plates past each other. Volcanoes and earthquakes commonly occur at plate boundaries due to the plates interacting and releasing energy.
Atomsandmolecules 100919202417-phpapp02
- The document discusses atoms, ions, molecules, elements, compounds, and chemical formulas and reactions.
- Atoms combine to form molecules, and molecules made of the same type of atom are elements, while molecules with different atom types are compounds.
- Chemical formulas use symbols and subscripts to represent the elements and number of each type of atom in a molecule or compound.
- Chemical reactions can release or absorb energy and are classified as exothermic or endothermic respectively.
Chapter 18 Review
River channels are landforms created by erosion from rivers and streams. During the water cycle, water gains energy from the sun during evaporation and loses energy during condensation. A watershed is a region of land drained by a river system, where smaller streams combine to form larger streams and rivers that eventually drain out of the area.

3+types+of+heat+transfer
There are 3 types of heat transfer: 1) conduction, which occurs through direct contact of molecules, best in solids; 2) convection, involving up/down currents in liquids and gases due to expansion/contraction of heated/cooled molecules; and 3) radiation, occurring through open space in gases by emission of electromagnetic waves.
Atom
To determine the subatomic particles of an atom, one must:
1. Gather the atomic number and mass, with the number representing protons and electrons and mass representing total protons and neutrons.
2. Identify protons as equal to the atomic number.
3. Identify electrons as equal to protons to maintain neutral charge.
4. Calculate neutrons by subtracting the atomic number from the rounded atomic mass.

The Coriolis effect causes apparent deflections in moving air as seen from Earth's rotating frame of reference. Air pressure decreases with altitude due to the weight of air above, and wind occurs as air moves from high to low pressure areas. Air masses develop distinct characteristics over different surfaces and temperatures, influencing weather patterns as high or low pressure systems move across regions. Warm and cold fronts form at boundaries between air masses with differing temperatures and humidity levels.
Newton's Laws of Motion
This document defines key terms related to motion and forces, including force, balanced vs unbalanced forces, inertia, mass, acceleration, and Newton's three laws of motion. It explains that an object at rest stays at rest and an object in motion stays in motion unless acted on by an unbalanced force, and that applying more force results in greater acceleration depending on an object's mass. It also notes that for every action there is an equal and opposite reaction force.
Force
A force is a push or pull that can cause an object to either remain at rest, change its speed, or alter its direction of motion. Forces are measured in Newtons and can be balanced, unbalanced, or net forces which are the combination of all individual forces acting on an object. Newton's first law of motion states that objects at rest remain at rest and objects in motion remain in motion with constant speed and direction unless acted upon by an unbalanced force.
Sea breeze and land breeze
The document discusses sea breezes and land breezes, which are caused by differences in how quickly land and water absorb and release heat. Water has a higher specific heat than land, so it warms and cools more slowly. During the day, land is heated faster by the sun through radiation. Warmer air over land rises through convection, pulling in the cooler air from over the ocean, creating a sea breeze. At night, land cools faster while the ocean retains heat, reversing the convection currents and forming a land breeze as the cooler air over land moves over the ocean.
Predation, mutualism, commensalism, or parasitism
Commensalism is a relationship where one species benefits while the other is neither harmed nor helped. Examples include clownfish living among anemone tentacles for protection from predators, and birds eating insects near grazing animals. Parasitism is a harmful relationship where one organism, usually physically smaller, benefits by living on or in the host organism. Examples include ticks and fleas drinking blood, and vines growing on trees. Mutualism benefits both species, such as flowers and pollinators, and algae and fungi in lichens. Predation is when one organism eats another, such as herbivores eating plants and carnivores eating animals.

Earths Interior Andie
The document describes the different layers that make up the interior of the Earth. It is divided into four main layers from outermost to innermost: the crust, mantle, outer core, and inner core. The crust is the thinnest layer and is made up of either oceanic or continental crust. Below the crust is the mantle, which is the largest layer and makes up most of the Earth's volume. At the center are the outer core, made of liquid iron and nickel, and the solid inner core, also made of iron and nickel.
Earths Interior Andie
The document describes the layers that make up the interior of the Earth. It is divided into four main layers from outermost to innermost: the crust, mantle, outer core, and inner core. Scientists use seismic waves from earthquakes to determine the composition and structure of these layers, since they cannot directly observe the interior. The waves travel at different speeds through solids and liquids in the Earth, providing clues about what materials exist in its core and where transitions between layers occur.
L3 EARTH'S INTERNAL HEAT.pptx
Earth's internal heat comes from three main sources:
1) The accretion of dust and gas particles during the Earth's formation released gravitational potential energy and caused internal heating.
2) Radioactive decay of elements in the Earth's core and mantle, such as uranium and potassium, continues to generate heat.
3) Frictional heating from convection currents in the mantle also contributes to the Earth's internal heat. Seismic waves have allowed scientists to indirectly learn about the Earth's layered structure despite only drilling about 7 miles deep.
Structure of the earth
The document summarizes the structure and composition of the Earth's main layers. It discusses that the Earth has an inner core, outer core, mantle, and crust. The crust varies in thickness and composition, with continental crust being thicker than oceanic crust. The mantle, made of solid hot rock, transfers heat via conduction and convection. The core is dense metal, mostly iron, and produces Earth's magnetic field through convection in the liquid outer core. Scientists determine this structure through geophysical surveys, seismic data, and properties of meteorites.
Earths Layers
The document summarizes the layers that make up the Earth. It is divided into four main layers from outer to inner: the crust, mantle, outer core, and inner core. The crust is the topmost layer and thinnest, varying in thickness from 5-100km. Below is the mantle, the largest layer making up 80% of the Earth's volume. Within the mantle are the lithosphere and asthenosphere. The outer core is liquid, while the inner core is solid iron and nickel, and is the source of Earth's magnetic field. Scientists study seismic waves to determine the composition of each layer without being able to directly observe or drill to the deep interior.

Earth interior
The document summarizes the four main layers of the Earth - the crust, mantle, outer core, and inner core. It describes each layer in 1-3 sentences. The crust is the top solid rocky layer that is thinnest under oceans. Below is the mantle, made of hot dense rock that flows slowly via convection currents. These currents also move the crustal plates. Deepest is the core, with the outer core a liquid layer of iron and nickel, and the inner solid ball an extremely hot and dense metallic solid.
EARTHS INTERIOR2.ppt
Geologists have learned about Earth's interior through two main types of evidence: direct evidence from rock samples and indirect evidence from seismic waves. Rock samples provide clues about conditions deep inside Earth, and sometimes volcanic eruptions blast rocks from over 100 km deep to the surface. Seismic waves from earthquakes reveal that Earth has layers like an onion, including a crust, mantle, and core that vary in size, composition, temperature, and pressure. The temperature increases rapidly within the first few tens of kilometers below the surface and continues rising towards the core. Pressure also increases greatly with depth.

Earths layers2
Earth can be divided into layers based on both chemical composition and physical properties. Chemically, Earth consists of a crust, mantle, and core. The crust is the outermost solid layer and is made up of silicates and aluminum. Below the crust is the mantle, made of hotter, denser rock rich in magnesium and iron. At the center is the core, mostly iron and nickel. Physically, Earth comprises the lithosphere, asthenosphere, mesosphere, outer core, and inner core, with the lithosphere forming the rigid outer plates and the inner core the solid center.
Inside the earth
The Earth has three main layers - crust, mantle, and core. The crust is the outermost layer and is divided into tectonic plates that slowly drift atop the mantle. Beneath the crust is the mantle, which is made of hot, dense rock and drives plate tectonics through convection currents. At the very center of the Earth is the extremely hot core, with a solid inner core surrounded by a liquid outer core.
Earth’s Interior-1.ppt
1) Earthquakes produce seismic waves that provide information about the interior of Earth as they travel through different layers at varying speeds.
2) Observations of P and S waves led scientists to conclude that Earth's core has a solid inner layer and a liquid outer layer, both composed of iron and nickel.
3) Between the core and crust is the mantle, made up of silicon, oxygen, iron and magnesium, which becomes solid rock under high temperature and pressure.
Plate tectonic (part 1)
The document discusses the composition and structure of the Earth. It is divided into three main layers - the crust, mantle, and core based on chemical composition. The crust is further divided into continental and oceanic crust. Physically, the Earth consists of the lithosphere, asthenosphere, mesosphere, outer core, and inner core. The theory of plate tectonics proposes that the lithosphere is broken into plates that move slowly over time, interacting at plate boundaries through spreading, subduction, and transformation. This explains patterns of volcanoes and earthquakes as well as helping to support the theory of continental drift.
Innovative work social science
The document summarizes the layered structure of Earth's interior. It describes four main layers from outer to inner - the crust, mantle, outer core, and inner core. The crust is the thin solid outer layer that life exists on. Below is the mantle, which is hot and flows over geological timescales. At the center are the outer core, made of liquid nickel and iron, and inner solid core, where temperatures and pressures are extreme.

Long and Short Term Enivornmental Changes
The document discusses different types of environmental changes including long-term changes that affect organisms over generations, short-term changes that immediately impact organisms, extinction which is when a species no longer exists, endangered species that have low numbers in their natural habitat, pollution which is contamination of the environment, biodiversity which is the number of different species in an area, and abundance which refers to the number of individuals of a species in an area.
Abiotic or Biotic factors
Ecosystems consist of interacting biotic and abiotic factors. Organisms rely on abiotic factors like temperature, water, and soil composition as well as biotic factors such as food sources and other species. Competition occurs when multiple individuals or populations rely on limited resources within the same niche. A limiting factor is any biotic or abiotic resource that, if depleted, prevents an organism or population from growing.
Ecology
Ecology is the scientific study of interactions between organisms and their environments, focusing on energy transfer. There are three main types of feeding relationships: producer-consumer, predator-prey, and parasite-host. Producers, like plants, make their own food through photosynthesis. Consumers eat other organisms for energy and include both predators that hunt prey and animals that eat plants or other animals. A food chain shows what organisms eat in a linear feeding order starting with producers, while a food web depicts the complex and interconnected feeding relationships in an ecosystem.
Ocean currents
Surface ocean currents are caused by winds and extend hundreds of feet deep, circulating heat around the globe by carrying warm water away from the equator and cool water from the poles. Deep currents are driven by water density differences, while upwelling and downwelling movements cycle nutrients and oxygen between surface and deep waters, impacting marine life. Ocean currents influence global climate by redistributing heat worldwide via transport of warm and cold water, changing overlying air temperatures.
Food webs
Animals get the energy they need to live from eating plants as herbivores, eating other animals as carnivores, or eating both plants and animals as omnivores. Food webs show what eats what in an ecosystem, with green plants as producers at the bottom and apex predators at the top that are prey to no other animal. Nearly all animals are consumers that get energy by consuming plants or other animals.
Periodic table
The document summarizes key concepts about the periodic table of elements, including:
1) Elements are organized into groups based on their valence electrons, with elements in the same group having similar properties.
2) Periods refer to horizontal rows, with the first element being very reactive and the last being an inactive gas.
3) Non-metals are generally poor conductors while metals are good conductors.
4) Metalloids have properties between metals and non-metals.
5) Reactive elements easily bond to complete their outer electron levels.
Atomic particles
The document discusses the basic particles that make up an atom: protons have a positive charge and are located in the nucleus, neutrons have no charge and are also in the nucleus, and electrons have a negative charge and orbit around the outside of the nucleus in an electron cloud.
8th grade taks review power point
The document summarizes physical and chemical changes, types of energy, parts of plant and animal cells, ecological succession, weathering and erosion processes, and making predictions in science. It provides examples to illustrate different concepts in middle school science.
Tectonic plates
The document discusses plate tectonics and how it relates to various geological phenomena. The Earth's crust is divided into major tectonic plates that move and interact along three types of plate boundaries. Divergent boundaries form new crust through seafloor spreading. Convergent boundaries result in earthquakes and volcanoes through processes like subduction. Transform boundaries involve plates sliding past one another. Volcanoes and earthquakes tend to occur at plate boundaries due to the stresses caused by plate interactions.
Timeline
Abraham Ortelius noticed in 1596 that the coastlines of America and Europe-Africa fit together like puzzle pieces, and attributed continental drift as the reason for this geometric coincidence. In 1785, James Hutton proposed that the Earth must be much older than previously thought to allow for geological processes like mountain erosion and sediment deposition. Albert Wegener suggested in 1912 that the supercontinent Pangaea had broken apart starting 200 million years ago, citing matching coastlines, fossil and climate evidence between continents. In 1960, Harry Hess discovered sea floor spreading and proposed new seafloor forms as hot material rises at mid-ocean ridges and flows away, carrying continents apart over geologic time.
Air mass movement reference pictures pp
An air mass is a large body of air with uniform temperature and moisture properties that forms over land or water surfaces. Air masses move across the Earth's surface and bring their characteristic conditions to other regions. Jet streams flow from west to east and influence the movement and interaction of warm and cold air masses. Different types of fronts form boundaries between contrasting air masses, including cold fronts where cold air pushes under warm air and warm fronts where warm air glides over cooler air.
Air mass
An air mass is a large body of air with similar temperature and moisture properties that can cover hundreds of thousands of square miles. Air masses originate over land or water source regions and take on the characteristics of the surface below over time. There are four main types of air masses defined by their source region in tropical or polar latitudes and whether that region is over land or water. When polar air meets warmer air over the United States, it causes the formation of the polar jet stream, a narrow belt of strong winds near the top of the troposphere that influences weather patterns and temperatures in the US.
Reasons for Seasons
1) The Earth's axis is tilted 23.5 degrees, which causes the hemispheres to receive different amounts of sunlight throughout the year, leading to seasons.
2) In summer, the hemisphere tilted toward the Sun receives more direct sunlight and experiences warmer temperatures, while the opposite hemisphere experiences winter.
3) Common misconceptions are that the Earth is closer to the Sun in summer and farther in winter, but the Earth's orbit is nearly circular and the distance variation is small compared to the tilt's effect.
Origins of the universe
The document discusses theories about the origins of the universe, including the steady state, oscillating model, and big bang theory. It describes how the big bang theory proposes that the universe began as one dense mass that violently exploded, sending matter and energy out in all directions to form stars and galaxies. It also explains how the observation of redshift shows that galaxies are moving further apart from each other as the universe expands.
