- 8. nutrients get washed out of the soil because of rain
- 11. when the largest amounts of rock and soil move because of gravity
- 12. all material that collects at the bottom of a hill
Down
- 1. rapid moving large chucks of land downhill
- 3. process that moves soil and rock to reshape that land
- 6. organic material, part of soil, must have for plants to grow
- 7. fan- a fan shaped deposit at the bottom of a hill where water does always flow
