What is erosion?

Erosion is when stuff gets worn away by things like wind, water, or ice, just like how you might wear down a toy by playing with it a lot.

Imagine you're sitting on the edge of a sandbox. You start digging with your hands, and little by little, the sand around you starts to move away. That's erosion in action, except instead of your hands, it could be rain, wind, or even a river doing all the work.

Think about a hillside after a big storm. The rain soaks into the ground and makes it soft, like wet clay. Then the water starts to flow down the hill, carrying bits of soil with it. Over time, that hill can get shorter and flatter, just like how your cookie might look after you eat all the chocolate chips.

Erosion is everywhere, in deserts where wind takes away sand, or near the beach where waves wear down rocks. It’s a slow but powerful process, shaping the world around us one tiny piece at a time.
