Which statement best describes the formation of metamorphic rocks?

A
Magma cools and crystallizes slowly beneath Earth’s surface.
B
Liquid lava erupts from a volcano and cools quickly at Earth’s surface.
C

How do erosion and deposition work together to form sand dunes?

A
Waves cause erosion along coastlines and deposit sand away from the shore.
B
Erosion occurs as surface water carries sediment and the sediment is deposited near oceans and lakes.
C
Glaciers cause erosion through the movement of large chunks of ice, which are deposited and form depressions.
D
Erosion occurs through deflation, and sand that was picked up is deposited against an obstruction.
