DRIVING FORCES OF EARTH'S DYNAMIC CRUST Tectonic plates are massive segments of the Earth's crust that float atop the upper mantle, a layer composed mostly of solid yet deformable rocks. These plates are not stationary, they are in constant motion, driven primarily by convection currents within the Earth's mantle. Convection currents are formed as a result of heat generated from the Earth's core. This heat causes hot, less dense material to rise toward the Earth's surface, while cooler, denser m

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.
