The crayfish takes in a little extra water, splits the exoskeleton behind the carapace, and climbs out which has to be a lot harder than it sounds.
The crayfish molts when it has grown to the point where the exoskeleton is too tight and it needs to grow more.
The exoskeleton is fairly rigid and does not grow with the crayfish.
There's a good series of diagrams of molting on this website:

Molting occurs when the crayfish has outgrown it's present body, the same is true of hermit crabs and tarantulas. This is a delicate time for all the creatures and when they are most prone to predation. The creature crawl out through the carapace.which is on the center back portion of the body.

The same way as all Arthropods do. Do your own homework. How are you ever going to learn anything? If you do your own research at the library, etc, the process of finding the information will teach you a great deal. Improve your mind, by improving your mind, instead of standing on the shoulders of others who have already learned.
