Why when it rains do worms come out?

They are escaping the water which sinks through the soil so they don't drown.

SInce the earthworm's environment is always wet or humid, it always contains some amount of water for the earthworms, so therefore, it is cool, but if a person was to dig up an earthworm, they would not adapt to the full heat, and try to dig back in again, to their original habitat. Oh yea, and if you do ever find an earthworm in your garden or so, the soil is good for you to plant, and the plants won't die unless you don't give them water. lol

it happens from a change of weather, it can happen if u dont take good care of yourself take your vitamins or wear socks all the time it happens.

omg- this is such a complex thing. i just took a parasite class and we talked about nothing but worms and amoebas. worms normally enter through digestion and then burrow their heads between villi. then it grows and matures and deposits eggs through feces. some worms use proglottids, some drop eggs directly into intestines. the eggs are then released out of the anus and ready for another host or vector. some worms end up going though the lamina propria in intestines and getting into hepatic duct and getting into the blood stream. worms can then get into the heart or even encyst in muscle and crippling the muscle if enough get in there. the trichino worm gets into arm muscles and enough render the arm useless.

i always thought it was because there was no humidity in the air...probably wrong, anyway. or maybe its because the warm climate doesnt allow the moisture to turn back into water. who knows? prob a weatherman.

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

The same thing that causes prizms in crystals.  It is the colors of light, the rain condenses them just as the crystal does

You need to find some earth worms..from somewhere.  Clear out a very cool dry earthy place in your yard where there is a lot of dirt.  Place the worms in the dirt(place plastic under the bottom layer so they can't escape) They will reproduce pretty rapidly...make sure to cover the dirt with leaves or an old blanket and keep it wet! Used to do this all the time with my Uncle before we went fishing.

The worms dig tunnels which help aerate the soil.  (helps get air into the soil.)  This allows the roots of plants to expand which helps to make the plant grow larger.\n\nI did a science project on worms when I was in the 5th grade....granted that was a long time ago, but I don't think worms have changed much since then.

Rain, rain and more rain.  Rain enough to have mud slides and trees down because the soil around their roots has washed away, and flooding and rain, rain, rain.\n\nWe suffered through it a few years ago, and it sounds like we may suffer through it again this winter.  Sometimes I feel like I am going to grow moss between my toes.

due to formations bearing bentonite type clay bases. in very basic terms they are like a dryed out sponge when water is added they swell. also when the bottom hole temps get too high your mud will cook out if water based. go online and look up mud logger or mud logging you should find some very useful info there or knowlage as to where to go for futher search

Earthworms do lay eggs.

yes,but its just soil. earthworms are decomposers so they release nutrients back into the soil

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)

So much to say...  There is a good possibility that these worms are not coming from a person using the shower, but live in or around the shower themselves.  Unless you are using your shower as a toilet, intestinal worms shouldn't show up in the shower.  There is a group of insects called drain flies that specialize in shower and sink drains.  They are harmless and should go away if you keep your drains clean.  They look like small dark sort of fuzzy worms with dark head capsules.  The adults are small, light grey with broad wings that end in a point. They are very fuzzy and are sometimes called moth flies.  I think they're cute.  Here's a link to a picture of an adult: http://images.google.com/imgres?imgurl=http://www.ento.psu.edu/ImageGallery/HouseMisc/Thumbs/Drain-fly03%2520Psychoda%2520lar117.jpg&imgrefurl=http://www.ento.psu.edu/ImageGallery/HouseMisc-2.htm&h=47&w=112&sz=4&tbnid=TMswDgiCpWjSLM:&tbnh=33&tbnw=81&hl=en&ei=ZiSMRPrzHI-SaeODwZMK&sig2=fHNR_-1ZtGtltcYvlFMWFA&start=1&prev=/images%3Fq%3Ddrain%2Bfly%2Blarva*%26svnum%3D10%26hl%3Den%26lr%3D%26client%3Dsafari%26rls%3Den-us%26sa%3DN

Flood : When it rains or snows, some of the water is retained by the soil, some is absorbed by vegetation, some evaporates, and the remainder, which reaches stream channels, is called runoff. Floods occur when soil and vegetation cannot absorb all the water; water then runs off the land in quantities that cannot be carried in stream channels or retained in natural ponds and constructed reservoirs (see Dam). About 30 percent of all precipitation is runoff, and this amount may be increased by melting snow masses. Periodic floods occur naturally on many rivers, forming an area known as the flood plain. These river floods often result from heavy rain, sometimes combined with melting snow, which causes the rivers to overflow their banks; a flood that rises and falls rapidly with little or no advance warning is called a flash flood. Flash floods usually result from intense rainfall over a relatively small area. Coastal areas are occasionally flooded by unusually high tides induced by severe winds over ocean surfaces, or by tsunamis caused by undersea earthquakes.\nDrought : Drought, condition of abnormally dry weather within a geographic region where some rain might usually be expected. A drought is thus quite different from aridity, which designates a region that is normally, or at least seasonally, dry.

Because you only notice it when it rains on you.  You don't notice when the sun is out or it's just cloudy.
