How Earth’s Crust Formed & Difference Between Tectonic Plates & Crust | GEO GIRL

This video covers how the outer most layer of Earth, the crust, formed, and the difference between Earth's crust and the lithospheric tectonic plates. Although many people think the tectonic plates are equivalent to continental crust, the lithosphere includes both the upper most part of the mantle and the crust. In fact, tectonic plates don't differentiate between continental and oceanic crust; most tectonic plates include both continental and oceanic crust. Boundaries between continental and oceanic crust that are not plate boundaries are called passive margins. However, many continental and oceanic crust boundaries are also plate boundaries due to the difference in density between plates containing oceanic crust and those containing continental crust. Oceanic plates are more dense and will subduct under continental plates, creating subduction zones. This is why supercontinents, like Pangea, have formed on and off throughout Earth's history.
