Across 1. When a mass of material slips down a curved surface because the slope becomes too steep. 6. Triangular area of sediment formed where the water enters an ocean or lake. 9. Water flowing as thin, broad sheets. 10. Sediments slowly shift position downhill. 11. Huge volumes of rock moved over hand and scour or scrap the soil and bedrock eroding it away. 12. Blocks of large rock break loose and tumble. 15. Sediment deposits beyond the glacier from melt water; deposited in layers. 16. Large deposits of fine-grained sediment. 17. Heavy rains mix with sediment causing it to become thick and pasty. 18. As glacier melts and retreats, it deposits till, a mixture of different sized sediments. 19. Wind blowing across loose sediment, removing the smaller particles.

Down 2. Process that adds gravel, sand, and boulders to a glacier's bottom and sides as water freezes and thaws, breaking off pieces of rock. 3. Rocks and soil move to end of glacier and get deposited creating a ridge. 4. Mound of sediment drifted by wind. 5. When a small stream forms during periods of heavy rain. The stream forms a channel, and eventually a gully. 7. From when sediment deposited in ice tunnels or by streams on top of the ice is left behind on Earth's surface. 8. The process by which Earth materials are worn away by moving water, glaciers, gravity, or wind. 13. Wind-blown sediment strikes rock, wearing it down (sandblasting. 14. The process by which Earth materials carried by wind, water, glaciers, or gravity.
