Across
- 5. the solid outer layer of the Earth that consists of the crust and the rigid upper part of the mantle
- 8. a mixture of gases that surrounds a planet like Earth
- 13. the part of Earth where life exists
- 15. the solid plastic layer of the mantle beneath the lithosphere; made of mantle rock that flows very slowly, which allows tectonic plates to move on top of it
- 16. the thin and solid outermost layer of the Earth above the mantle
- 17. a process in which the materials of Earth's surface are loosened, dissolved, or worn away and transported from one place to another by a natural agent; such as wind or gravity
- 19. in Earth science it is the layer of rock between the Earth's crust and core
- 20. the portion of Earth that is water
- 21. a gas molecule that is made up of three Oxygen atoms
Down
- 1. the energy that is transferred as electromagnetic waves, such as visible light and infrared waves
- 2. the lowest layer of the atmosphere, in which temperature drops at a constant rate as altitude increases; the layer of where weather conditions exists
- 3. the movement of matter due to differences in density that are caused by temperature variations; can result in the transfer of energy as heat
- 4. the warming of the surface and lower atmosphere of Earth that occurs when carbon dioxide, water vapor, and other gases in the air absorb and reradiate infrared radiation
- 6. the central part of the Earth below the mantle; also the center of the Sun
- 7. the transfer of energy as heat through a material
- 9. a block of lithosphere that consists of the crust and the rigid outermost part of the mantle
- 10. the mostly solid rocky part of Earth; extends from the center of the core to the surface of the crust
- 11. any form of water that falls to the Earth's surface from the clouds; includes rain, snow, sleet, and hail
- 12. a measure of the amount of dissolved salts in a given amount of liquid
- 14. the layer of the atmosphere that lies between the troposphere and mesophere and in which temperature increases as altitude increases; contains the ozone layer
- 17. the change of state from a liquid to a gas
- 18. the continuous movement of water between the atmosphere, the land, and the oceans
