WebSep 27, 2024 · Seafloor spreading is a geologic process in which tectonic plates —large slabs of Earth's lithosphere —split apart from each other. Seafloor spreading and other tectonic activity processes are the result of mantle convection. Mantle convection is the slow, churning motion of Earth’s mantle. Convection currents carry heat from the lower … WebMar 22, 2024 · Slab pull is thought to be a more significant gravitational force acting on plates. In the current understanding of plate motion the movement is driven by the weight of cold, older, dense plate material sinking into the mantle at deep ocean trenches and pulling the rest of the plate slab with them as gravity causes them to slide downwards.

Alfred Wegener produced evidence in 1912 that the continents are in motion, but because he could not explain what forces could move them, geologists rejected his ideas.

WebDec 21, 2024 · According to the theory of plate tectonics, the continents are moving because the plates the continents sit on are moving slowly over the molten mantle of the Earth. And yes, this same theory of ... Tectonics (from Latin tectonicus; from Ancient Greek τεκτονικός (tektonikós) 'pertaining to building') are the processes that control the structure and properties of the Earth's crust and its evolution through time. These include the processes of mountain building, the growth and behavior of the strong, old cores of continents known as cratons, and the ways in which the relatively rigid plates that constitute the Earth's outer shell interact with each other.
