Volcanoes do not stay ‘perfect cone’ forever. Nature reshapes them, one rainstorm, one landslide, one river at a time. A volcano is like a sandcastle: freshly built shapes are sharp, but with time the edges soften, collapse, and wash away. In this lesson you’ll learn to spot the difference between a recently active volcano and an older, eroded volcanic landscape, a skill that earns easy marks in CSEC descriptions. CSEC clue: If the diagram/photo looks ‘fresh and sharp’, think recently active. If it looks ‘worn, rounded, and cut by valleys’, think older/eroded.
