The exception is that … WebComputer Model of Mantle Convection. Scientists study mantle convection, or the flow of hot rock in the Earth's deep interior, in order to better understand how this flow shapes the surface of the Earth. When a solid, liquid, or gas is heated, it expands, becomes less dense, and rises. When it cools, it contracts, becomes more dense, and sinks.

WebAir going north turns to the right. Air traveling south turns to the left. The power of Earth’s spin to turn flowing air is known as the Coriolis Effect. If the Earth didn’t spin, there would be just one large convection cell between the equator and the North Pole and one large convection cell between the equator and the South Pole. WebThe Earth's crust. is broken up into pieces called plates. These plates move due to convection currents in the mantle . Heat from the core makes magma in the mantle rise towards the crust.
