Volcanoes – Windows into the Deep Earth
Volcanoes are the only direct route we have from the surface into the Earth's interior. We look at why some erupt as gentle rivers of lava while others detonate with the force of nuclear weapons, what actually drives an eruption, and how a single volcano can change the global climate for years.
