Weathering
What is weathering?
The breaking down of rock.
What is erosion?
The process in which wind, water, ice or other things move pieces of rock and soil over Earth's surface.
What are landforms?
Naturally occurring features of the Earth's surface.
A large chunk of ice moving across the land is called a what?
Glacier
What are the four agents of weathering?
Wind, water, waves and ice
Describe the process of erosion by water?
The process of sediment being moved by flowing/moving bodies of water.
Name three landforms.
Any: River delta, sand dune, u-shaped valley, v-shaped valley, canyon, beach, desert arch
How does water erode rocks?
Running water carries sediment from one place to another
How does frost wedging occur?
When water freezes inside rocks and thaws repeatedly eventually breaking it.
This type of erosion happens when sediments and small rocks are carried across the land.
what is wind erosion.
Very small bits of soil and rock that make up landforms are called what?
sediment
TRUE or FALSE: Deposition ends the process of erosion.
TRUE and FALSE
How do glaciers break down rock?
By moving slowly, creating friction and breaking down rock over time.
The land at the mouth of a river, where sediment builds up in a fan shape, is called this.
What is a delta?
When ocean waves drop sand and small rocks along the shore, they help create this landform.
What is a beach.
What 3 slow changes to earth's surface create landforms?
Weathering, erosion, deposition
What type of landform does weathering create?
Canyon or U-Shaped Valley
Erosion creates which type of landform?
Desert Arch
TRUE or FALSE: Islands are created by erosion and deposition.
FALSE
What is the main source of deposition?
Flowing water
How are weathering, erosion, deposition, and landforms connected?
Weathering, Erosion , and Deposition create a cycle that builds up and tears down Earth 's surface. Landforms are the outcome of the cycle.
