Granulometry (morphology)

Granulometry is like looking at a bunch of little things and figuring out how big they are. Imagine you have a bunch of marbles of different sizes. We want to figure out how many marbles are small, medium, or large. This is what granulometry is all about.

To do this, we can pour the marbles through different sized screens. The smallest marbles will fall through the smallest screen and the biggest ones will stay on top. We can count how many marbles went through each screen and make a graph that tells us how many marbles are small, medium, or large. This graph is called a granulometric curve.

Scientists use this kind of information to study all sorts of things, like how much sand is in a beach, or how much pollution is in the air. By figuring out how big the particles are, we can learn more about what we're looking at and how it works. It's kind of like sorting different kinds of candy by size, and then using that to figure out which kind is the most popular.
