Earth

2. an instrument used to detect ground movement
6. process of wind carrying away loose sediment mainly in desert regions
7. Weak Layers underground move downhill as a single unit
11. sediment builds up can be many miles wide excellent farming
13. Fastest longitudinal can go through solid and liquid
14. roll and tumble rocks against each other break into smaller pieces sediment acts like sand paper on rocks
15. Boundary plates that scrap off each other
16. Hotter and softer rock in the upper mantle
18. Dropping of weathered material somewhere else aids in creation of new landform
20. Gradual movement of soil downhill

1. rapid movement of large amounts of rock and soil (often occur after heavy rain or earthquake)
3. plates that pull apart
4. Earth’s crust and the top of the mantle
5. 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
8. The action of picking up and moving materials
9. plate move together
10. sand grains can wear away surface of rocks buildings like a piece of Sandpaper
12. in dry areas sediment collects when it Rains it loosens sediment and water rush downhill
17. Spot some places heated rock rises to make a volcano
19. 2nd waves transverse can only go through solid
