Earth

2. Boundary, plates that scrap off each other
5. process of wind carrying away loose sediment
7. rapid movement of large amounts of rock and soil (often occur after heavy rain or earthquake)
9. The action of picking up and moving materials
11. sand grains can wear away surface of rocks buildings like a piece of Sandpaper
17. Earth’s crust and the top of the mantle
19. Boundaty, plate move together
20. Hotter and softer rock in the upper mantle
21. Dropping of weathered material somewhere else aids in creation of new landform

1. in desert regions
3. in dry areas sediment collects when it Rains it loosens sediment and water rush downhill
4. an instrument used to detect ground movement
6. sediment builds up can be many miles wide excellent farming
8. Fastest longitudinal can go through solid and liquid
10. Weak Layers underground move downhill as a single unit
12. roll and tumble rocks against each other break into smaller pieces sediment acts like sand paper on rocks
13. 2nd waves transverse can only go through solid
14. has so much snow it can’t melt weight increases to form ice pressure is so much it partially melts at the bottom it starts moving
15. Gradual movement of soil downhill
16. Boundary, plates that pull apart
18. Spot, some places heated rock rises to make a volcano
