1. Earth’s Systems
Differentiate and describe the various interactions among Earth systems, including: atmosphere, hydrosphere, cryosphere, geosphere, and biosphere.

2. SCALE 3- Differentiate and show interactions among the geosphere, hydrosphere, cryosphere, atmosphere, and biosphere Describe the key parts of the Earth’s spheres. Illustrate the interaction between Earth’s spheres. 1- List the Earth’s spheres

3. IN: Sometimes fires burn large areas of forests, which are part of the biosphere. Other than the biosphere, which of Earth’s other spheres is a forest fire most likely to affect?
A geosphere
B. cryosphere
C. atmosphere
D. hydrosphere
Rationale
A is incorrect because the forest fire will not affect the layers of the geosphere that are below the soil in which the forest is growing.
B is incorrect because a forest fire is not likely to burn when there is water around, even in solid form.
C is correct because the products of the fire will disperse into the atmosphere.
D is incorrect because the hydrosphere is liquid water, which is not as likely as the atmosphere to be affected by the products of the fire.

4. OUT: Water is one kind of matter that can be exchanged by Earth’s spheres.
Explain how water is exchanged between the atmosphere and hydrosphere.

5. Ships encounter surface currents and waves as they travel across the ocean. Surface currents and waves form when energy from the sun causes two of Earth’s spheres to interact. Which two spheres interact to produce these waves and currents?
the geosphere and biosphere
the biosphere and hydrosphere
the cryosphere and atmosphere
the atmosphere and hydrosphere
Rationale
A is incorrect because the interaction of the geosphere (rocky Earth and its layers) and biosphere (living things) do not cause waves and currents to form.
B is incorrect because the interaction of the biosphere (living things) and hydrosphere (liquid water) do not cause waves and currents to form.
C is incorrect because the interaction of the cryosphere (frozen water) and atmosphere (gases surrounding Earth) do not cause waves and currents to form.
D is correct because the sun’s energy in the atmosphere (gases surrounding Earth) creates wind, and the interaction of wind and the hydrosphere (liquid water) produces waves and surface currents.

6. D is correct because the sun’s energy in the atmosphere (gases surrounding Earth) creates wind, and the interaction of wind and the hydrosphere (liquid water) produces waves and surface currents.

7. Why is Earth considered a system
Why is Earth considered a system? What are the main parts that make up the Earth system?

8. When trees die, they often fall on the ground and decompose
When trees die, they often fall on the ground and decompose. Which part of the Earth system includes dead and decomposed trees?
biosphere
B. geosphere
C. atmosphere
D. hydrosphere
Rationale
A is correct because the biosphere includes life-derived organic matter, such as dead plants and animals.
B is incorrect because the geosphere is the mostly solid, rocky part of the Earth system from the surface to the center of the core.
C is incorrect because the atmosphere is the layer of gases that surrounds Earth.
D is incorrect because the hydrosphere is the liquid water found on Earth.

9. Explain why Earth could be called “the water planet.”

10. Name two ways in which the Earth system relies on energy from the sun?

11. Which of these answers describes Earth’s atmosphere?
A. all living and once-living things
B. the mixture of gases that surrounds Earth
C. a mixture of nickel and iron below the mantle
D. all the salt and fresh liquid water on Earth’s surface
Rationale
A is incorrect because living and once-living things are part of the biosphere.
B is correct because the atmosphere is a mixture of nitrogen, oxygen, and other gases that surrounds Earth.
C is incorrect because the mixture of nickel and iron below the mantle describes the core.
D is incorrect because liquid water is the hydrosphere.

12. Describe sphere interactions you can infer from the scene.
