Erosion occurs when natural forces alter the landscape. What does it mean to alter a landscape?

to blow dust around

to change what the land looks like

to create a flood

to create a hurricane

1

Which term best describes the rate at which glacial erosion takes place?

1

Why is it hard to see glacial erosion in action?

because glaciers are so big

because light from glaciers refract too much

because glaciers move very very slow

because glacier erosions can be very subtle

1

What do floodplains, sandbars, and river deltas have in common?

they all have been formed by water erosion

They have all been formed by glacier erosion

they have all been formed by wind erosion

they have all be formed by sandblasting

blocking the wind

planting a tree

preventing rainfall

preventing the flow of rivers
