what are the main causes of convection currents in the …

Convection occurs in the asthenosphere due to heat generated in Earth’s core. This heat drives convection currents throughout the mantle because magma is able to move as a viscous fluid, rising and turning over again as it is heated from below. What are the three causes of …

Quick Answer: How Do Convection Currents In The Mantle Move …

Geologists have hypothesized that the movement of tectonic plates is related to convection currents in the earth’s mantle. Tremendous heat and pressure within the earth cause the hot magma to flow in convection currents. These currents cause the movement of the tectonic plates that make up the earth’s crust.

How do convection currents in the mantle move tectonic plates?

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.

What causes convection currents? When a liquid or gas is heated, the particles move faster. As the particles move faster, they spread apart. Because the particles of the heated fluid are farther apart, They occupy more space. The density decreases. (rises) But when a fluid cools, its particles move more slowly and settle together more closely.
