Slump |
| #2 | Sediments slowly shift downhill in the process of ___________. |
Creep |
| #3 | As ______________ move, they pick up boulders, gravel, and sand in an erosion process called plucking. |

| #4 | The scraping or wearing away of rock carried by wind or water is called ____________. |
Abrasion |
| #5 | A mound of sediments drifted by the wind is called a _______. |
Dune |
| Water Erosion and Deposition | ||
| #1 | _______ erosion occurs when sheets of water flowing across the land pick up and carry away sediments. |
Sheet erosion |
| #2 | A layer of permeable rock that lets water move freely. |
Aquifer |
| #3 | The area of land from which a stream or river collect runoff. |
Drainage Basin |
| #4 | Rainwater that flows across Earth's surface |
Runoff |
| #5 | What are the three major shoreline forces? |
Waves, currents, tides |
| Streams | ||
| #1 | Stream that flows swiftly through a steep valley |
Young |
| #2 | Flows slowly through a floodplain it has carved. |
Old |
| #3 | May have whitewater rapids and waterfalls. |
Young |
| #4 | Forms curves called meanders |
Mature |
| #5 | Erodes the stream bottom faster than the sides. |
Young |
| Final Question | |
What is the difference between weathering and erosion. |
Weathering is the process of breaking down rocks into smaller pieces where erosion is the moving of sediments. |
