Weathering
Trent R Jorgensen
What is weathering?
Physical weathering
In the picture to the right you will see a rock worn down by physical changes to make it flat and chipped.
Biological weathering
The picture to the right is an example of biological weathering. Because it is a tree root growing out of the ground and that means it broke or is breaking rock(rock is also soil)
Chemical weathering
The picture to the right is an example of chemical weathering. Because the rock has holes most likely caused by acidic rainwater.
Erosion
Erosion by wind
The picture to the right shows a beach and beaches have dunes or are formed by wind.
Erosion by water
In the picture you see a river that was strong enough to move away sand and rocks to connect to the ocean.
Erosion by gravity
In the picture to the right you see rocks at the bottom of a hill that were pushed down by gravity
Erosion by glaciers
The picture on the right through all the trees is a lake that was made by glaciers so its a finger lake.
