Chapter 3

4. Flow of heat from a warmer object to a cooler one
7. Mixture of nitrogen, oxygen, carbon dioxide, and other gases
9. O is a molecule made up of 3 atoms of oxygen
11. Water <2% of all water on earth
12. Plate Rigid outermost layer divided into pieces
13. Process by which water is heated by the sun and rises into atmosphere as water vapor
15. Effect Process in which gases trap heat near the earth
16. Condencation falling from clouds as rain
17. System Energy enters environment but matter does not
18. System Both energy and matter exchanged
20. Innermost layer
23. Cool, rigid layer, crust and uppermost part of mantle
24. Nearest earths surface, densest layer

1. Layer beneath crust
2. Cycle Continuous movement of water into air, onto land, and back to water source
3. solid part of earth, consists of all rock, soils and sediments on earth
5. Above troposphere,temps rise as altitude increases
6. Water vapor forms water droplets on dust particles
8. Quantity of dissolved salts
10. Layer beneath lithosphere - plastic, solid layer made of rock that flows slowly and allows tectonic plates to move on top
14. Transfer of heat through air current
19. Removal and transport of surface material
21. Transfer of energy across space and in the atmosphere
22. Thin outer layer made almost entirely of light elements
