why do worms come to the surface during or right after it rains?

Because they cant breathe in water. Drop one in a bucket of water and see how long it is before it dies.

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

Because when the storm forms, it forms from water that has evaporated from salt water. And the salt doesn't evaporate with the water.

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.

The only thing is, they don't always lie down when it is going to rain.  A lot of times you see them standing in a tight bunch right before it rains, too.  They almost always have their rear ends to the wind.  A lot of the "old timers" had ways of predicting the weather just by looking at natural things, guess this was just one of them.

They are caused by earthquakes, so are not influenced by the weather. For damage, see  http://www.tsunamispecialenvoy.org

Dave in NC answered it perfectly.  Ill just add, if you are asking why tornados form over land- The rapid increase in heat needed to cause formation of tornados generally occurs only over land, since water modulates changes in heat.  However, sometimes they do form, but they are called waterspouts, and usually occur near hurricanes.

Lots of regular gravel and sand of different sized granuels. They use finer material thedeeper in the leech pit you go until you will eventually get clean water out the other side. (Hopefully)

Major storm fronts have such strong updrafts, that they suck water, unevaporated, from the ocean and from lakes. Fish can get caught in these strong updrafts, and then "rain" out of the sky once the updraft that caught them dissipates or shifts.

Thats a simple science question.\nRainbows almost always appear during or right after a rainstorm. The water vapor in the air forms to act as a prism. With the right angles of sunlight in relation to the water vapor, the "prism" breaks the "white" or "ultraviolet" light up into it's true colors which are red, orange, yellow, blue violet and green. I always use to remember the primary colors by using the accronym, "roybug" changing the "u" to a "v" for the violet.

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.

parasite (like intestinal worms or mosquito).

Because the humidity levels are up, causing more moisture in the air before the actual rain.

They don't. They can happen anytime. Cyclones or hurricanes last for several days and may arrive at a place in the day or night. Earthquakes can happen when the plates in the earth move. The Indian Ocean earthquake that caused the Boxing Day 2004 tsunami happened around 8.00 am in local time. Mudslides occur after heavy rain or snow,

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

floods occur when the ground can't hold any more rain and the rivers and lakes crest over over their banks, this normally happens during the very heavy rain seasons that occur in most places where there is no place for the water to go like after severe thunderstorms, monsoons, hurricanes and typhones the waters receed once the rains stop and sun comes out to help with evaporation however the recession of the waters takes days and weeks to do on it's own so people normall end up pumping the water out of their homes also occurs when poorly built dams fail to hold the water in.

the worms are actually larvae -- they are pre-pubesent incects like flies.  the flies lay their eggs in food -- chances are you have eaten a billion fly eggs in food and never knew it.  anyway back to the story -- when the food gets the right mositure it signals the eggs hatch out larvae that live off the decomposing food  and they get big and fat and round.
