Hey kiddo! Let me explain the geochemistry of carbon to you like you're five years old.
Carbon is what we call an element - it's a part of the tiny, tiny particles that make up everything in the world. Even you and I are made up of carbon!
One of the really cool things about carbon is that it moves around a lot in the environment. It's in the air we breathe, the water we drink, and the food we eat.
But sometimes, carbon gets stuck in one place for a long time. We call this a carbon sink. Plants and trees are a great example of a carbon sink. When they use sunlight to grow, they take in carbon from the air and use it to build their leaves, stems, and roots.
But when plants and trees die and start to decompose, the carbon they've stored up gets released back into the air. This is called carbon dioxide, and it's what you hear people talking about when they talk about climate change.
Scientists study the way carbon moves around the environment using something called geochemistry. That just means they're looking at where carbon is found, how it's moving around, and what effect it has on the world.
So there you have it, kiddo! Carbon is a really important part of the world we live in, and scientists are working hard to understand it better.
