Question

How do convection currents affect tectonic plates.?

Answer 1

Hint: A tectonic plate is a huge, sporadically molded piece of rock, for the most part, made out of both continental and oceanic lithosphere. Plate size can fluctuate extraordinarily, from two or three hundred to thousands of kilometers across; the Pacific and Antarctic Plates are among the biggest. Tectonic plate theory is given on the basis of continental drift theory and seafloor spreading theory. Continental drift theory was given by Alfred Wegner and seafloor spreading theory was given by Harry Hess.

Complete answer: Convection flows drive the development of Earth's inflexible tectonic plates in the planet's liquid mantle. In spots where convection flows ascend towards the crust surface, tectonic plates move away from one another in a cycle known as seafloor spreading. Hot magma ascends to the outside crust surface, cracks create in the sea depths, and the magma pushes up and forms mid-ocean ridges. Mid-oceanic ridges or spreading focuses are separation points where two tectonic plates are moving from each other.

Note: Plate tectonics is a logical hypothesis depicting the enormous scope movement of seven huge plates and the developments of a bigger number of more modest plates of Earth's lithosphere since structural cycles started on Earth somewhere in the range of 3.5 billion years back. The model expands on the idea of continental float, a thought created during the principal many years of the twentieth century. The geoscientific network acknowledged plate-structural hypothesis after seafloor spreading was approved in the last part of the 1950s and mid-1960s.
