Weathering and erosion
Nick and Tyler
Mechanical and physical weathering
3 examples how it occurs: temperature changes- when rocks are really warm they expand a little when its not so warm it contracts.
Wind rain and waves- The wind makes sand particles blow into rocks and that's what makes rocks wear down
Freeze and thaw- It expands when it is frozen.
2 examples how it occurs: When carbon dioxide mixes with the water and rock. Also when oxygen and water react to the rock and cause it to rust.
2 examples of how it occurs: When rabbits or squirrels collect food. and weeds coming through your driveway.
What is Erosion
Erosion by wind
Sediment sizes that can be carried: smaller sized rocks because some wind is not that strong.
Effects on landforms and other structures: It can affect how much bigger the landform is.
Erosion by water
The sediment sizes that can be carried are small sizes because it is a small rock and can get carried fast.
What affects on land forms it has, The grand canyon that is how it formed when the lake washed all the sail away it made the grand canyon.
Erosion by Gravity
Sediment sizes are small and medium rock can get carried.
Effects on land forms are weathering and it could possibly over flow.
Erosion by glaciers
Sediment sizes that can get carried are small sizes to big sizes any where in its pathway.
Effects on land forms are the rock will then crack over time and lose different layers.
