Unit 1

2. places on earth where magma rises through thin spots of a tectonic plate not at the edges of the plate
4. boundaries that can result in seafloor spreading, rift valleys, volcanoes, and earthquakes
9. soil layers, form a soil profile
10. boundaries that can result in earthquakes
11. the ability of water to move through the soil, depends on texture of the soil
12. region of land that has become drier because of a higher elevation, like mountains, area blocks precipitation from reaching the land
13. manually breaking apart rock
14. picking up soil through stream bank erosion, mining, and runoff into nearby waterways
15. boundaries that can result in the creation of mountains, island arcs, earthquakes and volcanoes

1. air moving from west to east in the temperate zone (30-60 degrees latitude), distribute moisture brought by the trade winds
3. sinking air moves from the poles down to 60 degrees latitude, brining cold air masses down into the temperate zone creating heavy snow/rain
5. strong winds in the tropics that help move warm, moist air from the equator
6. bacteria or other small living things breaking rock down, usually uses both physical and chemical process
7. loss of topsoil caused by mostly wind and water
8. something dissolves or weakens the minerals holding the rock particles together which releases minerals for other organisms to use
