Across
- 4. the trapping of heat by greenhouse gases in the atmosphere that absorb energy; moderates temperatures
- 6. occurs when water on the surface changes to water vapor
- 9. the evaporation that occurs from the land along with the transpiration together
- 11. water that exists in the ground either in the soil or in rock layers below the surface.
- 12. underground layer of porous rock or soil that is saturated with groundwater
- 13. the cycle that moves nitrogen through the abiotic and biotic parts of ecosystems
- 16. weathering that changes the chemical composition of minerals that form at high temperatures and pressures to minerals that are stable at the Earth’s surface.
- 17. changes solid rock into pieces
Down
- 1. weathering that breaks rocks into smaller pieces without altering their chemical composition.
- 2. water that flows over the land from precipitation or melting of snow or ice.
- 3. process in which water falls from the atmosphere as rain, snow, sleet, or hail.
- 5. occurs when ice and snow change directly into water vapor
- 7. process in which water seeps into the ground
- 8. occurs when plants release water vapor through the pores of leaves
- 10. takes place globally: above, on, and below Earth.
- 14. the transport of weathered materials and sediments by water, wind, ice, or gravity.
- 15. the process in which water vapor changes to tiny droplets of liquid water
