Science Cafe: 'The Fire That Shapes the Earth: Volcanoes and Magma'
Christopher OP Hamilton, assistant professor of Lunar and Planetary Laboratory and Department of Geosciences, will present "The Fire That Shapes the Earth: Volcanoes and Magma."
Our Earth is a rocky planet, and inside, below the thin layer of solid rock crust on the surface, the planet is very hot – hot enough that rock can melt. That molten rock can shape the surface of the Earth by generating explosive volcanic eruptions and lava flows. Hamilton will explore how that molten rock, called magma, has continuously molded the surface of the Earth over millions of years, and how the same processes shape other planets and moons in our Solar System over even longer time scales.
