Across
- 2. cycle the continuous movement of water between the atmosphere, the land, and the oceans
- 3. a process in which hte 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, water, ice, or gravity
- 6. the thin and solid outermost layer of the earth above the mantle
- 8. the change of state from a gas to a liquid
- 10. the lowest layer of the atmosphere, in which temperature drops at a constant rate as altitutde increases; the part of the atmosphere where weather conditions exist
- 12. the transfer of energy as heath through a material
- 14. weathering the process by which rocks break down as a result of chemical reactions
- 15. water that contains insignificant amounts of salts, as in rivers and lakes
- 18. the solid, outer layer of the Earth that consists of the crust and the rigid upper part of the mantle
- 20. in Earth science, the layer of rock between the Earth's crust and core
- 22. a gas molecule that is made up of three oxygen atoms
- 23. the change of state from a liquid to a gas
- 24. the portion of Earth that is water
- 25. plate a block of lithosphere that consists of the crust and the rigid, outermost part of the mantle; also called lithospheric plate
Down
- 1. 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
- 4. the mostly solid, rocky part of Earth; extends from the center of the core to the surface of the crust
- 5. the energy that is transferred as eelctromagnetic waves, such as visible light and infrared waves
- 7. a measure of the amount of dissolve salts in a given liquid
- 9. the layer of the atmosphere that lies between the troposphere and the mesosphere and in which temperature increases as altitude increases; contains the ozone layer
- 11. any form of water that falls to the Earth's surface from the clouds; includes rain, snow, sleet, and hail
- 13. a mixture of gases that surrounds a planet, such as Earth
- 16. effect the warming of the surface and lower atmophse that occurs when carbond dioxide, water vapor, and other gases in the air absorb and reradiate infrared radiation
- 17. the movement of matter due to differences in density that are caused by temperature variations; can result in the transfer of energy
- 19. the part of Earth where life exists
- 21. the central part of the earth below the mantle; also the center of the sun
