Explanation:

An earthworm moves by using two different sets of muscles. Circular muscles loop around each segment, and longitudinal muscles run along the length of the body. ... Now the longitudinal muscles contract and the earthworm becomes shorter and wider or it bends from one side to the other, pulling the body forward.It has muscles. During the movement, earthworm first extends front part of the body keeping the rear portion fixed to the ground. ... It then shortens the body and pulls the rear end forward. In this way, by repeating such muscular expansions and contractions earthworm moves.
