erosion/deposition
| Question | Answer |
|---|---|
| The breakdown of rock is called what? | weathering |
| Physical weathering is the braking of rock into pieces without changing its____________________composition. | chemical |
| The removal of weathered material from one location to another is a destructive process called _________________________________. | erosion |
| What is rounding? | the wearing away of sharp edges on a rock during erosion |
| Erosion can _________________ sediment by size. | sort |
| The layering down or settling of eroded material is a constructive process called_________________________. | deposition |
| As water or wind slows down, it has less _______________________ and holds less sediment. | energy |
| The location where sediment is deposited is called a ______________________________ environment. | depositional |
| Landforms created by erosion are often ______________________ , jagged structures with cuts in layers of rock. | tall |
| Landforms created by deposition are usually on _________________________, low land. | flat |
| What is a pile of windblown sand? | dune |
| What is the result of water reaching gentler slopes? | groundwater |
| This moves slowly when it reaches flat land. | old stream |
| What is a C-shaped curve in a stream? | meander |
| This is caused by the rushing water of a young stream. | V-shaped valley |
| This can cause erosion and create a cave. | sea arch |
| A large deposit of sediment where a stream enters a large body of water | delta |
| this is caused by particles scraping against rock or other surfaces | abrasion |
| What are agents of weathering? | wind, ice, water and humans-this happens over time |
| What are the agents of erosion? | topography, wind, gravity and water |
| What is deposition? | When rock particles move to a different place and then settle |
| high energy equals | moving |
| low energy equals | deposition |
| What does deposition help form? | beds (sea beds) and helps fish |
