Why do earthworms come up on sidewalks when it rains?
Earthworms don't have lungs, they take in oxygen through their skin.
Underground they get oxygen from the air found between loose bits of soil. But when it rains, the air spaces fill up with water ( water can not hold as much oxygen as air ).
Earthworms can still get some oxygen from the water, But it soon runs out. So the earthworms crawl above ground. Above ground they get fresh air while they wait for the ground to dry. Some stay too long and dry out.
They can live up to two weeks under water as long as there is enough oxygen dissolved in the water
Oxygen dissolves into a mucous coating on a worm's skin then passes through the skin and into blood vessels. The skin must be moist for the oxygen to pass, that is why they wait until it rains.
There can be as many as a million earthworms under an acre of soil
First, earthworms are actually a colony of microscopic organisms that group up and form what we call "earthworms". While humans are mammals, "Earthworms" are not. "Earthworms" don't like the rain and will drown so they come up onto sidewalks and scare pussies as they crawl past these pussies. Humans are wimps, these earthworms, if split in half will become 2 earthworms! However, this operation doesn't always work so please do NOT attempt this and if…
Around here, when it rains really hard and there is standing water on the ground, the earthworms start to drown. They come out of their borrows and try to find higher ground. Trouble is, they either drowned or can't find their burrows again. So after a big rain there are all these dead worms all over the place. More than what the birds can gobble up in a week.
Worm come out when it rains because... they can! Ignore what other people say which probably is "they'll drown when their holes fill up with water." This isn't true, worms need water or wet earth to survive. Worms can't drown, and they only come up when its warm out when they are trying to escape a predator. A worm in the water
Death Valley is in the rain shadow of the tallest mountains of the Sierra Nevada. Those rains catch most of the moisture from the winter rains. The Summer rains of the western US come from the Pacific but come up through the Arizona or the Gulf of Mexico. So, Death Valley misses both the winter and summer rains.

The monsoon climate is found near India sri lanka and Bangladesh the monsoon climate is caused by the monsoon rains, basically they are winds that have come from Australia (southern hemisphere) and they blow up and left, then when they reach the southern hemisphere they blow right and cause a wet season for India known as the monsoon rains, because it rains for about 3 months really heavily.
Actually, it's NOT. An earthworm is great for the environment! It tunnels through the soil loosening it up and making it softer which helps plants' roots dig through better. The worm's tunnels create passages for air and water to enter the soil. An earthworm eats dead and decaying plant material and as the food is digested it is broken down into its basic minerals which are passed out in the worm's feces making the soil…
actually worms are hermaphrodites 1) Worms are coldblooded animals 2) Worms can eat their weight each day 3) There are 2,700 different kinds of earthworms 4) Depending on the species earthworms can live anywhere between 4 and 8 years 5) Earthworms don't have teeth but they do have a gizzard to break up their food 6) Earthworms are made up of 82% protein 7) If the head or the tail is accidentally cut off or…
Earthworms are not migratory creatures but they do not like much temperature variation and they prefer moist conditions. Some worms can enter a period called "estivation" which just means they are inactive and probably curled up in their burrow. Earthworms can also hibernate when it is too cold. So in winter, as long as they don't freeze, earthworms are probably sleeping not far under your feet.
