Earthworms like moist soil. They can survive in dry soils but they are not active. However if the drought is severe, they will die. In dry conditions, they can burrow deep into the soil to 1 metre, tie themselves in a knot, secrete a coating of mucous about themselves which dries and helps prevent water loss.
