Why do earthworms climb out of the soil after the rain?

why do earthworms crawl out of the soil after the rain? It turns out that earthworms are creatures that live in the soil. For them, the soil is their home. When it rains, the soil becomes wet and soft, which is a very comfortable environment for earthworms. So, they will crawl out of the soil.

let's look at the effect of temperature on earthworms. When it rains, the temperature in the air tends to decrease, while the temperature in the soil is relatively high. Because soil can absorb and keep heat, when it turns cold after rain, the temperature underground is still warmer than that on the ground. For earthworms, such a temperature is more suitable for their survival and activities.

rain can make the soil moist. Earthworms have many tiny pipes on their bodies, which are called white river systems. These pipes can help them breathe and excrete waste. When the soil is dry, these pipes will be blocked, making it difficult for earthworms to breathe. After the rain, the soil becomes wet and the pipes are unblocked, so the earthworm can breathe and move more easily.

Rain will also cause puddles on the soil surface. For earthworms, these puddles are good places for them to find food and breed. Because rainwater contains many microorganisms and organic substances, it is a rich food resource for earthworms. So when it rains, they will take the opportunity of the formation of puddles to leave the soil to find food and breed.

Earthworms climb out of the soil after rain because of the suitable temperature, moist soil and abundant food resources in the puddle. They like such a comfortable environment and adapt and maintain their lives in this way. However, it should be noted that if earthworms are caught after the rain, please treat them gently and try to put them back in their original living environment so that they can continue to enjoy the warmth and comfort of the mud house.
