WebPlate tectonics is an idea that explains how slow motions within the mantle of Earth move large segments of the crust, resulting in a gradual “drifting” of the continents as well as the formation of mountains and other large-scale geological features. WebJun 13, 2024 · This is exactly what plate tectonic theory says has happened. New oceanic crust is created by volcanism at the mid-ocean ridge. This newly formed oceanic crust is one of the key mechanisms by which continents move. Another key mechanism is subduction. Oceanic crust sinks into the mantle at subduction zones.

WebThis apparent fit is due to the fact the continents were once connected, and have since moved apart in what has been called continental drift. However, we now know that it is not just the continents that move, so a more correct term is plate tectonics. We can credit Alfred Wegener (Figure 4.1. 1) as the originator of this idea. WebPlate tectonics is a concept as basic to geology as evolution by natural selection is to biology or gravity is to understanding the orbits of planets. Looking at it from a different perspective, plate tectonics is a mechanism for Earth to transport heat efficiently from the interior, where it has accumulated, out to space. natural weed killer recipesWebThe mechanism behind Plate Tectonics Plate Tectonics: The Mechanism The main features of plate tectonics are: The Earth's surface is covered by a series of crustal plates.
