Imagine magma pushing into cracks underground like hot toothpaste, but it never erupts. Years later, rain, rivers and waves strip away the softer rocks above... and the hidden ‘magma sculptures’ appear! This topic is about the volcanic features you can’t see being made, only the landforms you see after erosion reveals them. Intrusive landforms are like a ‘geology surprise’: they form underground first, then erosion opens the curtain.
