Erosion occurs when natural forces alter the landscape. What does it mean to alter a landscape?
To blow dust around
To change what land looks like
To deposit silt at the mouth of a river
To create a floodplain
Which term BEST describes the rate at which glacial erosion takes place?
Quick
Short

Why is it hard to see glacial erosion in action?
Because glaciers are so big
Because light from glaciers refracts too much
Because glaciers move very, very slowly
Because glacial erosion is usually very subtle
What do floodplains, sandbars, and river deltas have in common?

Wind can gradually wear away the solid rock of river valleys AS MUCH AS thousands of feet over millions of years.
Wind can wear away the solid rock of river valleys NO MORE than several feet over many millions of years.
Which statement describes how rock characteristics affect rates of weathering?
