From the tallest mountains to the deepest ocean trenches, Earth's solid exterior is made up of a huge variety of rocks. New rocks are being formed by active volcanoes spewing lava or plutons cooling magma every day. But, most of the rocks we see on Earth are old: billions of years old! And, in Earth's collection of many, many rocks, no two are the same: they each reveal a different aspect of Earth's 4.568 billion years of history! In this class, we'll explore the broader aspects of Earth, both internally and externally. Our goal is to shed light on Earth's incredible features and processes. By the time you leave, we're sure you'll see the world (and maybe even other planets) in a much gneiss-er way! We promise: our schist is pretty cool!
