Question

why do earthworm come out of the soil during rainy season

Answer 1

earthworms came out of soil because in rainy season oxygen in water-logged soil may run out,then the worm has to come up to breathe.

Answer 2

Earthworm come out of the soil during rainy season because of the following reasons -

• 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.
