science erosion weathering
| Question | Answer |
|---|---|
| What is the difference between weathering and erosion? | Weathering breaks down rocks and weathering moves the broken-down material from one place to another |
| Why does deposition have a layered look? | Sediment drops according to its weight. The heaviest sediment drops first, and the lightest drops last. As a result depositions ofen have a layered look. |
| What are the 3 agents of erosion? | Water, wind and ice |
| Name and describe 3 names of mass movements. | Avalanche, soil creep (gravity pulls soil down the slope of a hill), mudflow (water combines with soil) |
| How are glaciers formed?` | Snow keeps falling year after year and doesn't melt in the summer and forms layers and compacts it into ice. The mass of ice becones so heavy that gravity causes it to begin sliding slowing downhill. |
| What is a pile of rocks and soil caused by a glacier called? | Moraines. |
| What is small particles produced by weathering? | Sediment |
| What is a dropping of sediments and rocks in a new location? | Deposition |
| What is deposits of sediments rich of nutrient at the mouth of a river? | Delta |
| What is weathered material moving from one place to another? | Erosion |
| What is an area that commonly floods? | A floodplain |
| What is sediment that a stream carrys? | Load |
| The primary force of erosion is? | Gravity |
| Weathering and erosion can occur together? True or False | True |
| When gravity is the primary factor in sediment moving, the movement is called? | mass movement |
| The slower the stream moves the more sediment it can move and pick up. True or False. | False. It is the faster. |
| Storms such as hurricanes decrease wave erosion and deposition. true or false. | False. It increases. |
