Bedform

Okay, so imagine you're playing in a sandbox. If you drag your hand through the sand, it will make a little hill, right? That's what we call a "bedform".

Now, imagine a river flowing on top of that sandbox. When the water flows over your little hill, it will push some of the sand downstream and leave some of it behind. Over time, that can create different shapes and patterns in the sand, like ripples or dunes. Those are also bedforms!

Bedforms are important because they can affect how water moves in rivers and oceans, and they can also provide clues to scientists about what kind of environment the sand was formed in. But for now, just remember that bedforms are little hills and bumps in sand or sediment, caused by things like wind or water moving over it. Cool, huh?
