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 […]

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, […]

Ever wondered why some landscapes slowly transform over time, while others seem to vanish in an instant? That’s the difference between erosion and scouring! These two natural processes may sound similar—and they both involve the movement of soil or sediment—but […]

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 […]

When it comes to geology, there’s an endless array of fascinating processes that shape our planet. Two that often leave people scratching their heads are petrification and lithification. These terms sound like they could be twins separated at birth, but […]
