Why is it that when it rains alot and worms attempt to make it across a slab of concrete to another section of dirt they dry up and die or become motionless?

When it rains, the worms come out because their tunnels flood, so they have to get out to keep from drowning. Unfortunately, most of them aren't smart enough to find their way back, so they dry up when the sun comes out.

Worms respire through their skin, so when the soil is saturated, they come to the surface to breathe. They probably find it even better breathing on a solid surface like concrete. Unfortunately for the worms, their sense of direction leaves something to be desired, and they tend to lose their way. Unable to find soil to crawl back into, they eventually begin to dry out...in addition to being permeable to oxygen, their skins aren't waterproof either!

they come out of the ground when it's raining because if they don't they will drown, and if they don't make it back in time they dry up in the sun
