Why does Iceland have so many volcanoes?
Volcanoes are famous for their explosive energy and the hot lava that bubbles and oozes out. They can be extremely destructive but are also beautiful forces of nature. In one country, Iceland, there are a LOT of volcanoes, but they've figured out how to use that lava for good.

I'm in Iceland, one of the most volcanically active regions in the world.
In fact, every day, scientists here are monitoring more than 30 volcanoes.
You might think with all that volcanic activity, it could get a little chaotic.
But let's find out how people in Iceland are using geothermal activity to their advantage.
Iceland sits right on top of what's known as the Mid-Atlantic Ridge, where the North American and Eurasian tectonic plates are slowly drifting apart.
That movement of the tectonic plates can cause earthquakes.
But this island is also what's known by geologists as a hotspot, where the underlying ground is warmer than the surface area above.
This combination makes for a lot of volcanic activity.
That sounds kind of scary, but it's actually something Iceland has adapted to.
Most of Iceland's energy comes from its unique geological circumstances.
Heat from magma under the surface and underground water reservoirs powers around 70% of the country.
It's used to heat homes and swimming pools and melt snow on streets.
Iceland may be a small country, but it is mighty in its understanding of geothermal activity, making it a global leader in clean energy, powered by the volcanoes that shaped its landscape.
