Earth

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
6. in dry areas sediment collects when it Rains it loosens sediment and water rush downhill
8. Fastest longitudinal can go through solid and liquid
9. sediment builds up can be many miles wide excellent farming
12. Earth’s crust and the top of the mantle
14. roll and tumble rocks against each other break into smaller pieces sediment acts like sand paper on rocks
16. Hotter and softer rock in the upper mantle
17. Boundary, plates that pull apart
19. an instrument used to detect ground movement
20. Spot, some places heated rock rises to make a volcano

1. 2nd waves transverse can only go through solid
2. process of wind carrying away loose sediment mainly in desert regions
3. The action of picking up and moving materials
4. Dropping of weathered material somewhere else aids in creation of new landform
7. Weak Layers underground move downhill as a single unit
10. rapid movement of large amounts of rock and soil (often occur after heavy rain or earthquake)
11. sand grains can wear away surface of rocks buildings like a piece of Sandpaper
13. Gradual movement of soil downhill
15. Boundaty, plate move together
18. Boundary, plates that scrap off each other
