Episode 484 - The links between the Core and the volcanos on the surface

May 24, 2022

How do seismic waves travel through our planet? Is it possible to 'slow down' a seismic wave? What causes 'hotspot volcanoes'? What strange things happen at the boundary between the core and the mantle? The mantle is a dynamic place, and pockets of 'dense' rock can slow and shape heat flow from deep below to the surface. Dense iron rich pockets of rock at the edge of the Core could influence where hotspot volcanoes occur.
