Movement of continents

Continental drift is the hypothesis that the Earth's continents have moved over geologic time relative to each other, thus appearing to have "drifted" across the ocean bed. The idea of continental drift has been subsumed into the science of plate tectonics, which studies the movement of the continents as they ride on plates of the Earth's lithosphere. The speculation that continents might have 'drifted' was first put forward by Abraham Ortelius in … Nettet19. feb. 2024 · Continental drift describes the movements of continents over the Earth's surface.

NettetContinental Drift Theory. Continental Drift: The movement of continents across the ocean bed is known as continental drift. This drifting takes millions of years to complete this process. Continental drift theory was given by Alfred Wegener in 1915. This theory has explained the origin of continents and ocean basins. Nettet2. apr. 2024 · What causes continents to move prove it with evidence? The causes of continental drift are perfectly explained by the plate tectonic theory. The earth’s outer shell is composed of plates that move a little bit every year. Heat coming from the interior of the earth triggers this movement to occur through convection currents inside the mantle.
