Is it possible for the earth to be sucked into a black hole? If so, what would happen?

It depends on the black hole, but with most black holes the Earth would be sucked in a little at a time -- and it would put on an X-ray light show. More details below.

Explanation:

First there has to be a black hole. If it's formed by gravitational collapse it must have at least the mass of several Suns, so its gravity will overwhelm that of the Sun and we are pulled out of our orbit. So we freeze to death before all the cool stuff happens. Bummer!
