Rocks, Soils, and What Hides Beneath Your Feet

Imagine digging a hole in your garden or a park. First you hit soft, dark soil. Dig deeper and — crunch — you hit hard rock. Have you ever picked up a pebble at the beach or a stone on a path? Rocks are all around us, even under your feet right now. Think about two rocks or stones you have seen before. Were they the same colour? The same texture — smooth or rough? This lesson will help you understand why rocks look and feel different, and where soil comes from.
