There are a lot of reasons. Usually to protect itself from predators, but sometimes they bury themselves to look for food.
There are several animals that bury themselves. Lizards, turtles, hedgehogs and the scarab beetle all bury themselves in dirt.

They do not bury themselves but do live in underground burrows. They do so as they need a place to escape severe weather, predators and a place to have their babies.
A hedgehog will build its den where they feel it is safest; this depends on the species.
If it is a wild animal or rodent you should call the Animal Control Center to come get it. Do not touch it. If it is a pet you can remove it and bury it or call a vet about animal disposal.
Just place the dead animal in a plastic bag, and bury it in the ground.
you just bury it and watch your friends or yourself fall into it
