Theory of how plates move
Did you know?
WebbThe movement of the plates is believed to result from the presence of large convection cells in the Earth's mantle which allow the rigid plates to move over the relatively plastic asthenosphere. The theory of plate tectonics was developed in the 1960s in an effort to explain the jigsawlike pattern of the Earth's continents. See Note at fault. WebbIn conclusion, plate tectonics is a scientific theory that explains how the Earth's surface is composed of large, rigid plates that move around on the Earth's surface over time. The movement of these plates is driven by convection currents in the mantle, and can be divided into three main types of movement: divergent, transform, and convergent ...

WebbDespite these failures in the modern theory of "plate tectonics," the notion that the earth's surface has been deformed at the margins of moving plate-like slabs appears to be a valid one. The facts indicate that the separation of the continents, rifting of the ocean floor, and underthrusting of ocean trenches, were accomplished by rapid processes, not occurring … WebbThe Earth’s tectonic plates are constantly moving like giant ‘rafts’ on top of the semi-molten mantle below. However, this movement is slow and rates vary from less than 2.5cm /yr to over 15cm/yr. One explanation for the …
