Tiny grains of sand are picked up
and carried off by the wind, which are then
blasted on the surface of rocks, smoothening
them

Q
  • most important agent of erosion
  • rock pieces are carried downstream to a suited depositional environment with the action of gravity
A

Rainwater

17
Q

gives water the energy to erode and carry away rock materials

A

Gravity

18
Q

can carry almost any size of rocks. The
greater the volume of water and the steeper the
slope, the bigger and more rocks can be
transported

A

Water

19
Q

Mass Movement

A

large masses of crustal
materials are moved by the action of gravity form one
place to another
