WebJan 30, 2024 · A natural convection current is the phenomenon that arises from the constant replacement of the heated fluid in the vicinity of the heat source by the adjacent present cooler fluid. When a liquid is heated, it expands, changes density or weight, and rises. As hotter, lighter liquid rises, cooler liquid from the top replaces it at the bottom.

WebOct 31, 2024 · Why is convection current in the asthenosphere important? Heat from deep within Earth is thought to keep the asthenosphere malleable, lubricating the undersides of Earth’s tectonic plates and allowing them to move.

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.
