The world is getting only slightly larger from meteors. But things change - like glaciers shift tons of stuff and scrapes off the tops of mountains and push it into valleys -- things like that. Plus wind and rain erodes one place and dinosaur bones can be found lying on the ground out in the open. And don't forget about the continental drift. New Jersey used to be in Africa.

Here's a simple way to explain it:
Get a pie pan and fill it with breadcrumbs. Now put a penny on it, and shake the pan back and forth for five minutes.
The constant movement of the breadcrumbs will cover the penny, even though you haven't added any more.
The earth's surface is in constant motion!

Maybe it's like this: The total amount of matter and energy remain constant - the earth isn't expanding. But stuff settles and other stuff gets built and piled up on top of what's settled. The amount of erosion, dirt sliding into oceans and rivers, and holes being dug evens out what's being dredged up and built on top of the other stuff.

Dirt just moves around, we never really gain or lose ---same as the theory of energy.
