1 Geosphere Classwork 1. Define geosphere. 2. Where is the oldest part of the Earth located? 3. What are the four layers of the Earth? List them in order from the outermost to the innermost. a. b. c. d. 4. What are the layers of the Earth made of? 5. Draw and label the layers of the earth.

2 Geosphere Homework 6. What is the top layer of the earth we live on called? What is it made of? 7. What does the prefix geo- mean? 8. What factors caused different layers to form within the Earth? 9. What layer of the Earth is the deepest? 10. Define soil.

3 Atmosphere Classwork 11. Define atmosphere. 12. What is the air in the atmosphere made up of? 13. What happens in the atmosphere as you get further from the Earth? 14. What is the ozone layer and what does it do? 15. Create a drawing or diagram of the rain shadow effect.

4 Atmosphere Homework 16. What does the prefix atmo- mean? 17. List the layers of the atmosphere from closest to Earth to furthest. a. b. c. d. e. 18. Describe how lifting occurs. 19. Why is the ozone layer so important to us here on Earth? What can happen if we receive too much ultraviolet (UV) radiation here on Earth? 20. How is a wind funnel created? What impact does it have on the wind?

5 Hydrosphere Classwork 21. Define hydrosphere. 22. What are the two different types of water here on Earth? What is the percentage of each type? 23. What is surface water? Give three examples. 24. How does the ocean water help regulate temperature? 25. Explain if the landforms found in the ocean are similar or different compared to landforms found on land. Give an example to support your claim.

6 Hydrosphere Homework 26. Give three examples of where water may be found in the hydrosphere. 27. What percentage of water is actually usable by humans and other animals and where is it found? 28. How do the oceans impact weather? 29. Where is the majority of freshwater on Earth located? 30. Your family just bought a piece of land without any surface water. Where could you find freshwater?

7 Biosphere Classwork 31. Define biosphere. 32. Describe the interactions between the different spheres for one of the following events. Try to list as many interaction as possible. a. Heavy rain in a desert biome b. Forest fire c. Volcanic eruption 33. What is the impact of rain on the biosphere?

8 Biosphere Homework 34. Define biomes and identify which one you live in. 35. Provide one example (not from our slides) for each of the relationships below: a. How the hydrosphere affects the biosphere? b. How the biosphere affects the atmosphere? c. How the biosphere affects the geosphere? d. How humans affects the biosphere.

9 Earth s Systems CW/HW Answer Key 1) Geosphere the system that includes the rocks, minerals and landforms that shape the Earth. 2) The oldest portion of the earth can be found in the very center in the Inner Core. 3) From outermost to innermost: Crust Mantle Outer Core Inner Core 4) The layers of the earth are made of rocks. They are in different phases. 5) Students should create a picture representing the layers of the earth and correctly label them. 6) The layer of the earth we live on is the crust. It is made up of soil and rocks. 7) Geo- means earth. 8) The layers of Earth were formed from an increase in Earth s gravity as well as an increase in pressure. 9) The inner core is the deepest layer of the Earth. 10) Soil is top-most layer of the Earth in which plants grow. It is made up of organic remains, clay and rock particles. 11) The atmosphere is a mixture of gases surrounding Earth, held in place by gravity. 12) 78% nitrogen, 21% oxygen and some water vapor and other elements. 13) The temperature and amount of pressure decrease the further away from earth you get. 14) The ozone layer starts 9 miles above earth s surface and it s made up of ozone (O3). It protects animals and plants from getting too much of the Sun s dangerous ultraviolet (UV) rays. 15) Students should create an accurate and detailed drawing of the rain shadow effect. 16) Atmo- means gas or vapor. 17) Troposphere, stratosphere, mesosphere, thermosphere, exosphere 18) Lifting occurs when mountains push the air upwards. Taller mountains push the air high enough to where the air reaches it saturation point and then precipitates. 19) The ozone layer helps protect us from the sun s harmful UV rays. If we receive too much UV radiation we will have a higher risk of getting skin cancer and earth s temperature increases. 20) Just as mountains can force wind and clouds upwards they also funnel the wind. Wind that encounter a blockage move through the path of least resistance. Wind funnels often see high speed winds 21) The hydrosphere describes the combined mass of water found on, under, and over the surface of a planet. 22) Water can either be salt water (97.5%) or fresh water (2.5%). 23) Surface water is the water that is located on the surface of the planet such as lakes, swamps, rivers, streams snow/ice and soil moisture. 24) Water responds to temperature change more slowly than does land. It takes longer to heat water, and longer for it to cool down. Therefore, locations near the oceans experience milder climate changes. 25) Landforms found in the ocean are similar to those found on land because many of them were created by the same forces.

10 26) Examples might include oceans, rivers, streams, groundwater, glaciers, atmosphere or other acceptable answers. 27) Only 2.5% of Earth s water is usable and is found as surface water (lakes, streams, rivers, etc.). 28) Energy from the sun is absorbed, stored and transported by the oceans which affects temperature, precipitation and wind. 29) The majority of freshwater can be found trapped in glaciers. 30) Groundwater is fresh water that can be found underground. Many people get water from wells. 31) The biosphere includes all living things on Earth as well as the land, sea and atmosphere in which they live. 32) Answers will vary but should highlight the interactions between the spheres of the earth for each example. 33) The amount of rain primarily determines what types of organisms live in a region. 34) Biomes are regions of the planet with similar climate and types of plants and animals. Biomes are classified as either terrestrial (land) or aquatic (water) biomes. 35) Answers will vary but should give examples of the interactions between the spheres for each example.
