What causes the asthenosphere to move?

Answer 1

The asthenoshere

acts like jello and allows the lithosphere, containing the plate, to move. Tectonic plates could not move without the asthenoshere.

Answer 2

The plastic like rock of the asthenosphere is able to move because of currents of heat from Earth's interior known as convection currents. The current is part of a process of heat transfer to a cooler area.

Answer 3

There is no "concrete" evidence, however the simplest and best regarded theory is that the dance of plate tectonics is driven by the restless heat of Earth's interior.

Earth retains some of its primordial heat within its core but the majority comes from the decay of radioactive elements. This heat, coupled with immense pressure means that the peridotite rocks that comprise the Earths mantle have the ability to move over millions of years. Mantle material near the core boundary is heated and becomes less dense, it rises until it hits the cooler upper mantle/lithosphere, where it cools and sinks back to begin the process again.

This constant and slow process provides the friction and force behind continental drift.

Answer 4

Movements in the asthenosphere are caused by currents of heated rock.

Answer 5

the convection currents
