WebJul 23, 2024 · Watch on. The theory of plate tectonics explained (2015) by Minute Earth (2:36 min.). The Earth is made up of several layers. The topmost layers are made up of the crust and the mantle. These layers are broken up into large interconnected plates. These plates are in constant motion. They float on a layer of molten rock within the Earth’s mantle. WebEarth’s crust and upper mantle (to a depth of about 60 kilometers) are divided into about a dozen tectonic plates that fit together like the pieces of a jigsaw puzzle . In some places, such as the Atlantic Ocean, the plates are moving apart; in others, such as off the western coast of South America, they are being forced together.

WebTheory of Plate Tectonics. When the concept of seafloor spreading came along, scientists recognized that it was the mechanism to explain how continents could move around Earth’s surface. Like the scientists before us, we will now merge the ideas of continental drift and seafloor spreading into the theory of plate tectonics.
