Weathering
What is weathering?

What is erosion?
The movement of rocks, sediment and soil from one location to another.
What is deposition?
Deposition is where the rock, sediment or soil is deposited or dropped after erosion.
What are the 3 types of weathering?
Chemical, Biological, and Mechanical
What forces or agents of change cause erosion?
running water, wind, ice and gravity
How does water deposition work?
When a river slows down it is not powerful enough to continue moving the rock and it is deposited in a new location of the river.
What is ice wedging what type of weathering is it?
When water freezes in rocks and cracks them apart. It is mechanical weathering.
How do glaciers cause erosion?
They slide down the mountain moving rock, sediment and soil from one location to another.
How does wind deposition work?
What is root wedging? What type of weathering is it?
When a plant grows in the crack of a rock and splits it apart. It is biological weathering.
How does wind cause erosion?
The wind picks up small sediments such as sand or dirt and moves it to another location.
How does glacial deposition work?
After a glacier stops moving and the ice melts the rock that was carried with it is deposited in a new location.
What is chemical weathering caused by?
Carbon dioxide, oxygen, water and various acids.
How are canyons formed?
Canyons are formed by water running through the area for millions of years and pushing the rock to a new location.
What is a delta?
A delta is where a river reaches another body of water and deposits enough soil to create new landforms.
