| Water | more sediments are eroded by this than any other agent of erosion |
| sheet erosion | rainwater flowing into lower elevations outside of a channel and carrying sediments with it cause __________________. |
| alluvial fan | one type of deposit resulting from water erosion that is shaped like a triangle |

| gully erosion | rill erosion may evolve into _________________. |
| sediment | as water moves along a stream, it constantly picks ______________ from the bottom and sides of its channel |
| stream | the rill erosion of a ___________ that frequently flows in the same path may evolve into a gully erosion |
| level surface | when water begins flowing on a ________________, it slows down, loses energy of motion, and drops its sediments |
| downstream | water usually loses energy of motion as it moves _________________. |
| gravity | the pull of _____________ causes water to move downslope |
| channel | because of erosion, a stream continually cuts a deeper and wider _____________ |
| rain | rill erosion begins when a small stream forms during a heavy _______________. |
| energy of motion | when the Mississippi River reaches the Gulf of Mexico, it loses much of its _________________ |
| deposit | a delta is formed when water does not ________________ its sediments until it empties into an ocean, lake, or gulf |
