@spacefacts.and.theories (IG) Posted this awesome graphic of earth’s crust composition, I learned something! Also, I didn’t realize there was that much silicon dioxide. Crazy how these elements come together and form such vast surface features! | Geography Now

EARTH'S COMPOSITION Earth is made up of distinct layers: a solid crust, a silicate rich mantle, and a dense core primarily of iron and nickel. Together, these layers drive plate tectonics, fuel volcanism, and generate Earth’s magnetic field, shaping the planet’s dynamic nature.
