Describe an erosional change that occurs rapidly. Describe an erosional change that occurs slowly.
fast: earthquakes, volcanoes, flooding, and landslides.
slow: weathering and erosion. These processes shape landforms with water, ice, wind.
In your own words define deposition.
Deposition is the dropping of rocks and sediment in another place.
Weathering, erosion, & deposition are changes to the Earth from
wind
water
ice
all of the above
