Chngs to Earth's Sur
Changes to Earth's Surface Unit C Chapter 1
| Question | Answer |
|---|---|
| What are landforms? | physical features on earth's surface |
| What are some examples of landforms? | deltas, dunes, terminal moraines |
| What are some forces that change landforms? | flowing water, waves, wind, ice and even movements inside the earth |
| What can cause landforms to change? | wind, water, hurricanes |
| What natural forces can SUDDEN changes? | deposition and mass movement |
| What usually cause SLOW change? | weathering and erosion |
| What is weathering? | the process of breaking rock, soil into tiny pieces of particles called sediment |
| What is erosion? | the process of moving sediment from one place to another |
| What is sediment? | tiny pieces of rock particles that have been broken down through the process of weathering |
| What is deposition? | the process of dropping or depositing sediment in a new location |
| How does wind cause weathering? | Wind can carry bits of rocks and sand that weather rock surfaces |
| How does wind cause erosion? | wind blows sand into large mounds called dunes |
| What are glaciers? | thick sheet of ice formed in areas where more snow falls during the winter than melts in the summer |
| Does glaciers move? | glaciers SEEM to stand still but they actually move |
| How does glaciers cause weathering and erosion? | Due to glaciers great size it erodes everything under it |
| What kind of landforms do wind and glaciers generally form? | terminal moraines form by glaciers and wind erosion creates dunes |
| What is mass movement? | the downhill movement of rocks and soil because of gravity |
| What are some examples of mass movement? | mudslides and glaciers |
| What is a possible disadvantage of paving a new road on broken limestone rock? | sink holes |
| What kind of landform can be found when a glacier stops moving forward and deposit the sediments it has been carrying with it? | terminal moraines |
| What kind of landform can be formed by deposition of sediment from and underwater volcano? | new islands |
| What kind of landforms cna be formed by eroding forces of a river channel? | oxbow lake |
| What is oxbow lake? | when rivers flow it automatically picks the shortest route, it flow cuts off the loop. The old loop forms a crescent-shaped body of water called oxbow lake |
| What kind of landform can be formed by the deposition of sediment at the mouth of a river? | deltas |
| What are some surface process that change landforms | volcanoes, water and glaciers |
| What forces causes erosion and deposition | water |
