Question

why do earthworm come out of soil during rainy season

Answer 1

Answer:

When the rain hits the ground it creates vibrations on the soil surface. This causes earthworms to come out of their burrows to the surface. Earthworms find it easier to travel across the surface of the soil when it is wet, as they need a moist environment to survive.

Answer 2

Answer:

After the rainfall, when the soil becomes wet,loose and waterlogged, it becomes easier for the worms travel through. Now, the worms feel more comfortable to travel through the surface rather than the inside portion of the soil. That's why, they come out from the soil, in order to utilise the surface for long travelling.

Other theories suggest that the coming out of the worms after the rainfall is associated with the breathing of the earthworm.

Now, there are still debates about this topic among the researchers. So, we cannot accept any answer as the completely accurate.
