What are the four agents that constantly change the earth’s landforms?
Water • Wind • Ice • Mass movement
The process of breaking rock into silt, sand, clay, and other tiny pieces
Rivers can carve deep canyons • Ocean waves can weather cliffs • Freezes in cracks and expands breaking the rock apart • Acid rain dissolves rock • Tumbles rocks into each other
What is the process called of dropping it into a new location?
Waves take the sediment from the cliffs to the beach • Rainfall carries it to rivers and streams • Rivers carry it to their banks • Some rivers carry it to their mouths
The new land that has been deposited in a triangle shape near the mouth of a river
