WebThe theory of plate tectonics states that (A) earthquakes and volcanic activity result from convection motion in the lithosphere. (B) buoyant lithospheric plates float on top of the rigid asthenosphere. (C) the plates move in conveyor-belt fashion as new crust is generated at the continental margins and destroyed at the mid-ocean ridges. WebApr 28, 2024 · The researchers believe this shift is the earliest proof that modern-like plate motion happened between 2 and 4 billion years ago, suggesting that the plates pushed and pulled in ways unlike those seen earlier periods, when the Earth’s crust moved less.

WebPlate tectonics refers to the movement of the rigid plates around the surface of Earth. The outer portion of the planet, or lithosphere, is relatively rigid because it is relatively cold. The lithosphere varies in thickness but is typically a hundred or so kilometers thick. It includes the upper mantle and both the continental and oceanic crust.

WebJul 7, 2024 · How do tectonic plates move? Plates at our planet’s surface move because of the intense heat in the Earth’s core that causes molten rock in the mantle layer to move. It moves in a pattern called a convection cell that forms when warm material rises, cools, and eventually sink down. As the cooled material sinks down, it is warmed and rises again.
