This document discusses the processes of erosion and deposition that shape the landscape over time. Erosion through weathering breaks down rock and soil, allowing water to carry sediments downstream where deposition occurs, building up deltas. As plants grow on deposited sediments, they produce oxygen through photosynthesis, renewing the atmosphere for animals and humans to breathe.

Erosion and deposition occur through a multi-step process. Weathering erodes the landscape through various means. Water then carries eroded materials through the path of least resistance, eventually depositing sediments where plants and animals can live in deltas near oceans. Over time, plant growth through photosynthesis releases oxygen into the atmosphere, allowing people and animals to breathe. Upon further review, the author realizes their initial analysis of this process lacked specific details like a sphere-to-sphere impact and location of erosion, leaving unclear the environmental dynamics affecting erosion rates.
Water lecture
Water is essential for life and covers most of the Earth's surface. It exists in three states - liquid, solid (ice), and gas (water vapor). Water is a polar molecule made of one oxygen atom bonded to two hydrogen atoms. Its unique properties, like being a universal solvent and having a high heat capacity, help regulate the Earth's climate and temperature. Water is distributed throughout the universe and is critical for habitability in Earth's "Goldilocks zone" where its three states can exist simultaneously.
Water lecture
Water is essential for life, making up 75% of most living organisms. It shapes the Earth, nourishes life, moderates climate, dissolves minerals, and provides many other benefits. However, only 1/8% of the planet's water is fresh and available. We must develop stewardship approaches to sustainably manage our precious water resources.
Properties of water1
This document provides information on various properties of water that are important for life. It discusses high surface tension, strong cohesive properties, being colorless to allow light transmission, existing as a liquid at room temperature, high latent heat of vaporization, high specific heat capacity, and lower density when frozen compared to liquid form. Each property is described in terms of its significance for living organisms, such as forming habitats on water surfaces, transport through plants, or providing stable conditions in cells.
Biochem 1 water notes
This document provides an overview of the importance and properties of water. It discusses how water is essential to many bodily processes since humans are about 60% water. Water is able to carry out these functions because of its unique molecular structure and polarity. The polarity of water allows it to dissolve many other substances and interact with ions through hydrogen bonding. These cohesive and adhesive properties give water its high surface tension and ability to act as a solvent. The document also briefly covers pH, acids, bases, and buffers.
Water ecosystems lcr
Water ecosystems can be divided into saltwater and freshwater. Saltwater ecosystems include oceans, seas and some lakes, and contain animals like fish, sharks, whales and penguins. Freshwater ecosystems contain very little salt and include rivers, streams, lakes and ponds, and are home to animals such as trout, otters, bullfrogs and turtles. In both saltwater and freshwater ecosystems, plants and animals are typically found in shallow, sunlit areas near the surface.
Biochem 1 water notes
Water makes up about 60% of the human body and is essential for many bodily processes. It is highly polar, with hydrogen atoms sharing electrons unevenly with the oxygen atom. This polarity allows water to dissolve many other polar substances and act as a solvent in solutions like blood. Water's cohesive hydrogen bonding gives it high surface tension and allows it to carry out important functions like regulating body temperature and transporting nutrients and waste.
Cycles of matter
The document discusses several important cycles in nature. It begins by explaining the energy cycle in an ecosystem, with the sun providing energy to plants, which are then consumed by animals higher up the food chain. It then describes the water cycle, in which water evaporates from bodies of water into the air as vapor, condenses into clouds, and falls as precipitation, collecting and evaporating again. It also summarizes the carbon cycle, where carbon is absorbed by plants and released when plants and animals respire or decay, and the nitrogen cycle, where nitrogen in the air is absorbed by plants and recycled through the ecosystem. These cycles are essential for recycling scarce resources and sustaining life.

The document discusses several important cycles in nature. It begins by explaining the energy cycle in an ecosystem, with the sun providing energy to plants, which are then consumed by animals higher up the food chain. It then describes the water cycle, in which water evaporates from bodies of water into the air as vapor, condenses into clouds, and falls as precipitation, collecting and evaporating again. It also summarizes the carbon cycle, where carbon is absorbed by plants and released when plants and animals respire or decay, and the nitrogen cycle, where nitrogen in the air is absorbed by plants and recycled through the ecosystem. These cycles are essential for recycling scarce resources and sustaining life.
Ecosystems
An ecosystem is composed of a biotic community and its abiotic surroundings. Matter cycles through ecosystems as energy from the sun or chemicals moves through food webs. Terrestrial ecosystems include Mediterranean and Atlantic forests, while aquatic ecosystems contain fluvial, wetland, coastal, and marine biomes inhabited by plankton, nekton, and benthos. Ecosystems face threats from invasive species, pollution, overexploitation, and other human-induced environmental changes.
Fresh Water Notes (Ch 11)Andie
The document discusses the Earth's freshwater resources. It notes that only 3% of the Earth's water is freshwater, with 97% being saltwater. Of the 3% freshwater, 76% is locked up in ice sheets and glaciers, while 23% is underground. The water cycle, which is powered by the sun, moves water between bodies of water, land, living things, and the atmosphere through evaporation, condensation, and precipitation. Fresh surface water exists in rivers, lakes, and wetlands. Underground, freshwater is stored in aquifers, which are porous rock that can be accessed through wells. The document also discusses freshwater pollution and the importance of water conservation.
Hydrology
Hydroelectric power is a renewable source of energy that generates electricity from the kinetic energy of flowing water. Dams are constructed to trap water in reservoirs, allowing it to flow through tunnels and turn turbines that drive generators. The amount of power generated depends on the head, or vertical distance water falls, and water flow. While hydroelectric power has advantages of being renewable and producing no emissions, dams can negatively impact the environment by flooding habitat and disrupting river ecology.
2.2 Cycles Of Matter
The three important cycles of matter are the water cycle, carbon and oxygen cycles, and nitrogen cycle. The water cycle involves evaporation, condensation, and precipitation in a continuous process where water moves from the Earth's surface to the atmosphere and back. Evaporation changes liquid water to a gas, condensation changes a gas to a liquid forming clouds, and precipitation causes liquid drops to fall back to Earth as rain, snow, sleet or hail. The carbon and oxygen cycles involve producers using carbon dioxide and releasing oxygen through photosynthesis. Nitrogen fixation by bacteria changes nitrogen gas into a usable form, occurring in nodules on plant roots to make nitrogen available to organisms.
Water properties ppt
The document discusses the molecular structure and properties of water. It notes that water is a polar molecule, with slightly positive and negative ends due to the uneven sharing of electrons between the oxygen and hydrogen atoms. This polarity allows water molecules to form hydrogen bonds with each other and other polar substances. The hydrogen bonding between water molecules gives water many unique properties that help to moderate Earth's temperature and make it suitable for life, including its high heat capacity, ability to change state from solid to liquid to gas, and ability to dissolve many other substances.
Natural resources
This document discusses how people use natural resources like water. It provides information on the major ways water resources are used: agriculture, industry, households, recreation, and environmental activities. For agriculture, it notes that 69% of water worldwide is used for irrigation. For industry, it estimates that 15% of water use is industrial, in areas like power plants. It also provides proposals for conserving water resources like educating people to close taps when not in use and preventing water pollution from trash and fertilizers. The document discusses some issues with water resources like climate change impacts, business expansion pressures, and recent news about water privatization efforts in Colombia.
5.1 PHYSICAL CHARACTERISTICS OF WATER
Water covers 70% of the Earth's surface and exists as a liquid at room temperature due to its high surface tension. Water is able to be drawn up from roots to leaves of plants through capillary action. Pure water has specific physical properties including boiling at 100°C, freezing at 0°C, and having a density of 1g/cm3. Evaporation of water is increased by factors like higher temperature, lower humidity, increased surface area, and movement of air.
E Science[1]
The document discusses the water cycle and various bodies of water. It describes the water cycle as the continuous movement of water between the earth and atmosphere, involving evaporation, transpiration, precipitation, and collection of water on land or in bodies of water. It also discusses the physical and chemical properties of water, including its chemical makeup of H2O and categories of saline water. Finally, it identifies and describes different types of flowing bodies of water like rivers, creeks, and brooks, as well as non-flowing bodies of water like oceans, lakes, ponds, reservoirs, sloughs, marshes and estuaries.
Brackish water
Estuaries are wetland areas where rivers meet the sea that contain brackish water, which is a mixture of fresh and salty water. They provide unique habitats for many plant and animal species that have adapted to the brackish environment. Estuaries and their surrounding wetlands are transitional zones between fresh water and salt water ecosystems. Desalination is a process that removes salt and minerals from water, such as seawater, to produce fresh water suitable for human use or agriculture. It is an important process for obtaining fresh water in dry regions and on ships. However, desalination is more expensive than other fresh water sources due to its high energy usage.

The Chesapeake Bay watershed covers 64,000 square miles across six states and supports over 3,600 plant and animal species. However, the bay is threatened by excessive nitrogen and phosphorus pollution which causes dead zones with low oxygen levels that can kill aquatic life. One of the leading causes of the problem is decomposition of algae blooms that deplete oxygen in bottom waters for up to 10 months each year. The Chesapeake Bay Foundation's Philip Merrill Environmental Center aims to set an example through practices like using recycled materials, waterless composting toilets, native landscaping requiring no water or fertilizer, and habitat restoration projects. Efforts are also underway to restore oyster and wetland
aquatic environment and biodiversity
This document discusses ecological concepts such as mortality, r-selected species, habitat, ecological niche, and carrying capacity. It defines mortality as the rate at which individuals die in a population. R-selected species are those that live in environments below carrying capacity and can grow rapidly when conditions are favorable. Habitat refers to where an organism lives, while ecological niche describes its role in an ecosystem. Niche can be defined by variables like temperature and resources. Carrying capacity is the maximum population size an environment can sustain indefinitely.

Properties of water ppt
Water is a polar molecule that forms hydrogen bonds between other water molecules. This gives water unusual properties like being a universal solvent, having high surface tension and heat of vaporization. The hydrogen bonds allow water molecules to bond together through cohesion and adhesion, enabling plants to transport water against gravity. Water's density also prevents freezing from the bottom up, making environments more stable for aquatic organisms.
Cycling of matter
Matter cycles between living and nonliving components in ecosystems through biogeochemical cycles. Key cycles discussed include water, carbon, oxygen, and nitrogen. Matter is recycled through producers, consumers, and decomposers. Toxins can accumulate and concentrate in organisms at higher trophic levels since they are not biodegradable and biomass decreases at each level. This was seen with DDT accumulation in birds, interfering with egg shell formation and reproduction.
Water resources

El poema explora las perspectivas diferentes entre "aquí" y "allá", sugiriendo que algo puede verse de una manera desde una ubicación pero de otra manera desde otra ubicación distante. Lo que es "aquí" no necesariamente es lo mismo que "allá", y viceversa, por lo que es importante considerar múltiples puntos de vista.
Ode' to Bilingual Education
El poema explora las perspectivas diferentes de "aquí" y "allá", sugiriendo que lo que se ve desde una posición puede ser diferente a lo que se ve desde otra y que es importante considerar múltiples puntos de vista. También juega con la idea de que cosas de un lugar pueden eventualmente moverse al otro lugar y ser vistas de manera diferente.

Strengths in the addie model
The document discusses the strengths of the ADDIE (analysis, design, development, implementation, evaluation) instructional design model. It notes that while some argue ADDIE does little to encourage innovation, its strength is that it provides a linear, step-by-step process for developing lessons. This structure allows for clear objectives and organization. ADDIE is also cost-effective, saves time for learners and instructors, and promotes effective learning through consistent application. Although other models have been proposed, they still incorporate ADDIE's basic structure of analyzing, designing, developing, implementing, and evaluating instruction.

Tac2010 standardsetting
The document summarizes the process used by the Texas Education Agency to set performance standards, or cut points, for the State of Texas Assessments of Academic Readiness (STAAR). It involves:
1) Conducting validity and linking studies to relate student performance across courses, grades, and other assessments.
2) Convening committees of educators and policymakers to develop performance level labels and definitions based on college and career readiness standards.
3) Using the research findings and committee recommendations to set initial cut scores, which are reviewed periodically as more data becomes available.
How the moon affects the earth
The document discusses several ways that the Moon affects the Earth, including causing tides, influencing Earth's seasons by causing its axial tilt, and slowing Earth's rotational speed which moderated wind speeds and led to milder weather. It also notes that scientists believe a large object collided with Earth in the past and that debris from this collision formed the Moon. The Moon's gravity helps stabilize Earth's axis and prevents severe wobbling that could cause more extreme weather.
Jefferson 4th grade moon menu
The Moon Menu is an activity sheet that provides options for learning about the moon through drawing, writing, modeling and role playing. Students are asked to name the moon phase for an appetizer, choose drawing or writing about the moon for the entree, select at least two side dishes like journaling about the moon's importance or drawing its phases, and have an optional dessert of drawing features they wish were on the moon.
What do you know about the moon
The document discusses several facts about the moon, including that it is about one-quarter the size of Earth, made of rock, and reflects sunlight giving it a bright appearance. It has no atmosphere or weather and the low gravity allows astronauts to jump higher but makes living there challenging without protective gear and life support. The surface contains mountains and craters formed by asteroid impacts.
Comment response to team member
Albert Rodriguez thanked Victoria Lopez for her feedback on his Dust Bowl report. He acknowledged that he drew information from multiple sources, including Victoria and other group members as well as sources provided in the class assignment. Victoria Lopez complimented Albert Rodriguez on his extensive prior knowledge of the Dust Bowl topic. She noted that she felt limited to just the assigned sources for her individual report, while Albert demonstrated consideration of various contributing factors through his thoughtful questions.
Volcano scenario albert rodriguez
The document discusses a scenario where a panel has asked a team to study the potential impacts of an eruption of Mt. Rainier that is similar in magnitude to the 1991 eruption of Mt. Pinatubo in the Philippines. The team will use the PBL model and Earth system science approach to prepare a response. They identify what is known, such as the community's concerns, and what is unknown, like the eruption patterns and regional climate and topography. The team needs to develop an early warning system, evacuation plan, and salvage priority plan to protect resources. The problem statement is that a Mt. Rainier eruption would affect the region's population, flora and fauna, and natural resources
