Porosity might not be a word you throw around at the dinner table, but in geology, it’s a game-changer. It’s the measure of all those tiny (or not-so-tiny) void spaces inside rocks and sediments where things like water, oil, gas, […]

Have you ever wondered how rocks, those seemingly unchangeable chunks of Earth, can completely transform into something new? It’s a little like watching a caterpillar become a butterfly—except with intense heat, crushing pressure, and no cocoon involved. This process is […]

Erosion is one of those natural processes we don’t think much about — until it starts to cause problems, like flooding, loss of soil, or even changing the landscape we know. But what is erosion, exactly? And how does it […]

If you’ve ever picked up a rock, you might have wondered how it came to be. Sure, they’re solid, hard, and often seem like they’ve been around forever. But beneath their tough exterior, sedimentary rocks are the result of a […]

Now let’s switch gears to metamorphism, a process that takes rocks on a much more intense geological journey. If diagenesis is like baking bread at low heat, metamorphism is the rock equivalent of forging steel in a furnace. It occurs […]
