I like rocks.
I think and talk about plate tectonics, geological hazards like earthquakes, the history of the Earth system, and how we silly humans can live sustainably on our amazing planet.

A thick sliver of ultramafic mantle rock, which has a much mechanical strength at 25-50 km depth due to its higher melting temperature, helps to explain how the Himalayas have gotten as high as they are without collapsing in on themselves.
