What are sedimentary rocks?

Sedimentary rocks are like layer cakes made by nature over many years.

Imagine you're playing with your toys and stacking them one on top of another. Over time, each layer gets squished a little more, just like how sedimentary rocks form when tiny pieces of rock, sand, or shells get pressed together under the earth's surface.

How They’re Made

Sedimentary rocks are made from pieces that fall down, like leaves falling to the ground, or sand being washed by water. These pieces can come from old rocks, plants, or even animals that lived long ago. When they get buried under lots of other layers, they press together and turn into a new kind of rock.

Why They’re Cool

Sometimes you can see shells or tiny stones inside sedimentary rocks, it's like looking at a time capsule from the past! These clues help scientists figure out what the earth was like millions of years ago.
