📚 Topic Summary
Landslides happen when gravity pulls rocks, soil, and debris down a slope. Gravity is the force that pulls everything towards the Earth's center. Think of it like this: gravity is what keeps your feet on the ground and what makes a ball fall when you drop it. When the force of gravity is stronger than what's holding the slope together (like plants and rocks), a landslide can occur. Rain, earthquakes, and even human activities can make landslides more likely.
