Earth

3. plate move together
6. process of wind carrying away loose sediment mainly in desert regions
11. Fastest longitudinal can go through solid and liquid
12. The action of picking up and moving materials
13. in dry areas sediment collects when it Rains it loosens sediment and water rush downhill
15. Hotter and softer rock in the upper mantle
17. an instrument used to detect ground movement
19. plates that pull apart
20. Boundary plates that scrap off each other

1. sand grains can wear away surface of rocks buildings like a piece of Sandpaper
2. sediment builds up can be many miles wide excellent farming
4. rapid movement of large amounts of rock and soil (often occur after heavy rain or earthquake)
5. roll and tumble rocks against each other break into smaller pieces sediment acts like sand paper on rocks
7. Spot some places heated rock rises to make a volcano
8. Dropping of weathered material somewhere else aids in creation of new landform
9. Earth’s crust and the top of the mantle
10. 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
14. 2nd waves transverse can only go through solid
16. Weak Layers underground move downhill as a single unit
18. Gradual movement of soil downhill
