WebApr 22, 2024 · An enduring question in geology is when Earth's tectonic plates began pushing and pulling in a process that helped the planet evolve and shaped its continents into the ones that exist today. Some ... WebMay 23, 2024 · Tectonic plates are 62 miles thick and are made up of the continental crust and the oceanic crust. Slab pull is the most relevant force that affects the movement of tectonic plates. Convection refers to specific cells within the Earth’s mantle that create heat. The heat makes the solid rocks move upwards while the colder rocks move downwards.
WebAs Earth’s plates slowly move and grind against each other, they build the mountains that tower above us. If the plates stick, then slip, they release their energy through the earthquakes that shake us. The USGS is dedicated to better understanding our planet and the processes that shape our planet.
