The sun heats the air near the earth’s equator, which becomes less dense and rises upward. As it rises, it cools and becomes less dense than the air around it, spreading out and descending toward the equator again. WebMay 30, 2024 · What causes convection currents in the asthenosphere? Convection currents are the result of differential heating. Lighter (less dense), warm material rises while heavier (more dense) cool material sinks.

Tectonic plates are large pieces of rock that make up the surface of the earth, a bit like puzzle pieces. They float on top of the asthenosphere. Because the asthenosphere is not completely solid, convection currents within it move each plate at a slightly different rate and direction.

WebThe convection current moves the lithosphere, which is the solid outer layer of the Earth. The lithosphere is broken into tectonic plates. The Earth's plates move on a hot spot in the mantle, which is called a convection current. WebJul 22, 2016 · The main causes of convection currents in the asthenosphere is A. density and temperature.
