And how they affect each other

2. Apollo 17 astronauts captured this snapshot of the Earth system on their way to the moon in Essentially everything that was a part of the system then is still a part of the system today—that's why it's considered a closed system. All of the matter (solid, liquid, and gas) and all of the processes that move energy and materials from one part of the planet to another make up the Earth system.

3. Earth is divided in Four main Sphere

4. Earth is divided into 4 main SPHERES
The names of the four spheres come from Greek words for stone (litho), air, (atmo), water (hydro), and life (bio)

5. Biosphere -Thin layer of air, land, and water where living things exist.
Includes all living things and their relationships
Ranges from 10km above sea level (used by birds in flight) to depths of the ocean such as the Puerto Rico trench, at more than 8 kilometres deep.
This layer ranges from heights of up to ten kilometres above sea level, used by some birds in flight, to depths of the ocean such as the Puerto Rico trench, at more than 8 kilometres deep.
Biosphere 2

6. Geosphere All of the rocks, minerals and ground found on and in Earth
Includes all mountains on the surface, as well as liquid rock in the mantle below the surface as well as minerals and metals of the outer and inner cores.
The Geosphere. Since 'geo' means 'ground,' the geosphere describes all of the rocks, minerals and ground that are found on and in Earth. This includes all of the mountains on the surface, as well as all of the liquid rock in the mantle below us and the minerals and metals of the outer and inner cores.

7. Geosphere Crust: The thin, outer layer of the earth.
Less than 1% of the Earth's mass.
Made of solid rock, broken into plates.
Mantle: Molten rock on which plates float. Contains 67% of the earth's mass.
Core: Inner layer of the Earth. Made of both solid and liquid metals.
The Geosphere. Since 'geo' means 'ground,' the geosphere describes all of the rocks, minerals and ground that are found on and in Earth. This includes all of the mountains on the surface, as well as all of the liquid rock in the mantle below us and the minerals and metals of the outer and inner cores.

8. Hydrosphere
Includes all of the rivers, lakes, streams, oceans, groundwater, polar ice caps, glaciers and moisture in the air (like rain and snow).
The hydrosphere is found on the surface of Earth , but also extends down several miles below, as well as several miles up into the atmosphere.

9. Evaporation
Condensation
Precipitation
Water flows into lakes and rivers and oceans
Hydrosphere interacts with Biosphere to provide water for plants and animals

10. Atmosphere
Includes all the air above the surface of the Earth all the way to space.
The air contains 79% nitrogen, less than 21% oxygen, and a small amount of carbon dioxide and other gases.
The earth is surrounded by atmoshphere, which protects us from radiation from the sun, falling meteors and toxic gases. It consists of five elayers within the atmosphere.
Most of the atmosphere is found close to the surface of the Earth where the air is most dense.

11. How do Earth’s Spheres Interact?
How are Earth’s Spheres Interacting? • What sphere interactions can you infer from this photograph? • When you identify sphere interactions, think of one feature in the image at a time, decide which sphere it is a part of, then consider how it interacts with the other spheres. • With a partner, describe interactions in this scene,

12. Identify at least two spheres and describe interactions
Plants (biosphere) draw water (hydrosphere) and nutrients from the soil (geosphere) and release water vapor into the atmosphere. Humans (biosphere) use farm machinery (manufactured from geosphere materials) to plow the fields, and the atmosphere brings precipitation (hydrosphere) to water the plants. Energy from the sun is stored by plants (biosphere). When humans or animals (biosphere) eat the plants, they acquire the energy originally captured by the plants. Humans expend some of this energy arranging bricks and wood (geosphere and biosphere) into buildings.

13. Humans (biosphere) built a dam out of rock materials (geosphere)
Humans (biosphere) built a dam out of rock materials (geosphere). • Water in the lake (hydrosphere) seeps into the cliff walls behind the dam, becoming groundwater (geosphere), or evaporating into the air (atmosphere). • Humans (biosphere) harness energy from the water (hydrosphere) by having it spin turbines (geosphere, because the turbines come from metal ores in the ground) to produce electricity.

14. dentify the four different spheres of the Earth in the example.
What will happen if the trees do not get enough water?
Describe the interactions between the hydrosphere and the biosphere in this example.
What will happen if the carbon dioxide levels change dramatically?
Describe the interaction between the atmosphere and the biosphere in this example.
Is there any interaction between the lithosphere and the hydrosphere in this example?
