Reasons Why Earthworms Come Out During Rains

Earthworms have a huge role in our environment. They convert the bigger pieces of matter into something that can make the soil fertile. They do this important role by pulling the matter down to the soil. Earthworms are commonly seen on the ground just after the rain. They come out and wiggle their bodies as if they are enjoying the water. Many scientists believe that several factors affect the earthworms' behavior after the rain. This may include the temperature, ph balance as well as their natural instincts.

1. The first possible answer to the question why do earthworms come out in the rain is because of the change in the ground's temperature that they feel when rain pours in. Most earthworms live deep underground because of the warm temperature under layers of soil.

2. The second possible answer to the question why do earthworms come out in the rain is because of the change in the soil's pH value. Other experts also think that it could be that some soils have the tendency to form a higher concentration of cadmium when rains pour.

3. The third feasible answer to the question why do earthworms come out in the rain is because of the different variability that is phenotypic in nature. There may be just some worms that cannot submerge in the water for a long time.

4. The fourth feasible answer to the question why do earthworms come out in the rain is because some kinds of worms require little oxygen. The presence of water makes for more content of oxygen on the ground. However the P. corethrurus is a worm that has tolerance for getting immersed in water hence they don't come out during a rain.

5. The fifth possible answer to the question why do earthworms come out in the rain is perhaps because of their natural behavior. It is a possibility that most worms behave this way during rains and it may not be because of their need for more oxygen or less thereof.

6. Another likely reason why earthworms come out during the rains is because they love moisture. The worms would like to rise above the surface to bask in the moisture on the soil. This is the same behavior isopods exhibit during wet seasons when they rise up and climb plants or trees. This is also a similar behavior for most earthworms when they come out.
