Why do earthworms go above the ground when it rains?

Earthworms can't drown.\n\nWorm experts can’t agree on the reason earthworms come out in the rain. Some believe it’s simply because they can. After all, it’s the only time worms can come above ground while keeping their skin nice and moist. Other experts believe worms come out when it rains so they can find other worms with whom to mate. Some people believe worms would drown if they didn’t come up to the surface during a heavy rain. But most experts agree that this probably isn’t the reason, since worms can live for a long time underwater.

Locomotion.  The setae on each segment allow the earthworm to "grip" the earth while their longitutinal and circular muscles contract the rest of the body into place to apply forward pressure to "burrow" through the earth.

They stay in the sky because they are part of our atmosphere. \n\nDefinition of a cloud - A visible body of very fine water droplets or ice particles suspended in the atmosphere at altitudes ranging up to several miles above sea level. \n\nThey aren't forced to drop to the ground unless they become larger droplets or bigger ice particles forcing them down by gravity - which is what would be rain or a storm.

Because of it's velocity. It's the same principle that holds objects in orbit around the earth. The Objects are freefalling towards the ground, but they also have velocity that propels them forward in what, if the earths effect was removed would have been a straight line. As it is it becomes an arc, a sort of parabole. If the initial velocity is great enough the earth will be curving under the object faster than the object is falling towards it, so it will never reach the ground - it goes into orbit.

Taking a guess here but I  would think in a way.. some plants have growth underground like carrots, potatoes, onions, etc. The underground roots stay underground lol, they absorb fluids, aka water and grow from underneath then the stems are actually what blossoms out of the dirt. It is the result of the outgrowth the root has made. I have no idea what I'm saying here :P

That is a good & interesting question.\n\nIn all logical aspects, this should occur due to the fact that everything in nature trys to balance out. This includes things like air pressure; it travels from high to low areas of pressure. In the same manner, everything that is uphill or of higher elevation trys to balance w/ those that are of lower elevation; hence erosion & drainage basins in general.\n\nIn order for this to occur, a lot of sediment would have to be washed into the drainage basin's streams & rivers. That would take a very long time.\n\nAlthough I think the answer here has to do with the fact that the earth's crust rebounds in a process called isostatic adjustment.\n\nWhen material is removed from the crust to another location, weight is taken off of an area. The crust will readjust to the former height by rising slightly.\n\nIt's just like placing several blocks of wood in a container of water. As you take off one of the blocks, the rest of them will rise in response to the reduced load.\n\nThats my answer & I'm sticking to it.\n\n:)

I *think* it's because they breathe through their skin - so when the soil and the underground fills up with rain water, they must come to the surface or drown. \n(I'm not 100% sure about this)

Earthworm is the common name for the larger members of the Oligochaeta (which is either a class or subclass depending on the author) in the phylum Annelida. In classical systems they were placed in the order Opisthopora, on the basis of the male pores opening to the outside of body posterior to the female pores, even though the male segments are anterior to the female. Cladistic studies have supported placing them instead in the Haplotaxida, which also includes the family Haplotaxidae. Folk names for earthworm include "dew-worm", "night crawler" and "angleworm

Try digging them up, or wait till it rains, they tend to come up to the surface.

So that they can have a nice dry spot - if they waited until after it had rained to lie down then they would get wet tummys!\n\nI'm not sure how they know when it's going to rain though...maybe some kind of 6th sense?!

Commonly goes deeper in the ground when the surface soil becomes too dry, too hot, too cold, or too wet.

The warm air pushes the moisture higher into the colder air layers....as the moisture droplets freeze together  they fall and enter the warm air currents which pushes them back up to the cold layers..this happens until enough layers are built up, that the updrafts can't support the weight and the ice falls to the ground in the form of hailstones.

It's a chemical reaction between the materials used in country roads and natural raindrops.  The drops gather together (congeal) and become frogs.  Where I grew up it was suburban city concrete sidewalks and worms.

I have seen butterflies in very light rain but they apparently find safe harbor in heavy rains as do most animals. They have a powdery substance on their wings which probably would not do well to get wet and possibly cause them to no longer be able to fly.\nThis is a really cool website on butterflies..you might like to check it out.\nhttp://www.christiananswers.net/kids/butterflies.html

Because the ant has such a large surface area comparative to its mass, it's likely that at any height on Earth when atmosphere is present that an ant will survive the fall.\n\nThere are several species of ant which are able to glide, maneuvering their body as they fall.  These are mostly tree-dwelling species in places like the Amazon rainforest.  If they happen to fall from a tree, they simply glide back to the trunk of the tree and climb back up.

when it rains, it pours.\n\nHope you don't live on/near a hillside.

That answer is true.\n\nThe water table rises & falls in response to rainfall amounts.\n\nWhen there is little rain, the water table will lower thereby affecting the wells in surrounding areas.\n\nOn the flip side, when there are great amounts of rain, the water table will rise. Sometimes the rain is so great that the water table reaches the surface & the ground is saturated.
