Hey, Suji, I just watched this video that imagines what it was like when Mount Baekdu erupted a long time ago. It was fascinating but also kind of terrifying. Have you seen it? |
|
|
Oh yeah, I saw that too, Peter! Mount Baekdu has a pretty explosive history. It's interesting how volcanoes can be both beautiful and destructive. Do you know why they erupt? |
|
|
I have a basic idea, but I'd love to understand more. Can you explain it? |
|
|
Sure! Volcanic eruptions are primarily driven by the buildup of pressure from gases and magma beneath the Earth's surface. Essentially, the Earth's mantle melts in certain spots, creating magma, which is less dense than the surrounding solid rock. |

So the magma rises because it's less dense? |
