Why was the rocket to go to the moon so big? How do they get home?

Something I've never understood. It takes a giant rocket to achieve escape velocity and leave the Earth. The Apollo mission made it all the way to the moon. But in all the pictures I've ever seen, the only thing they've got on the moon is a lander, a small capsule on legs. Where's the rocket they used to get off the moon? How did they get off the moon? I know the moon is much smaller and has almost no atmosphere, but is leaving it really as easy as firing a few booster rockets? Why is the rocket to leave the Earth so much bigger?
