During the movement, earthworm first extends front part of the body keeping the rear portion fixed to the ground. Then it fixes the front and releases the rear end. It then shortens the body and pulls the rear end forward. In this way, by repeating such muscular expansions and contractions earthworm moves.

Answer:
How do earthworms move? Earthworms have groups of bristles on each segment of the body that move in and out to grip surfaces as they stretch and contract their muscles to push themselves forward or backward. They tend to move forward.
