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 |
