Convection currents are the result of differential heating. Lighter (less dense), warm material rises while heavier (more dense) cool material sinks . It is this movement that creates circulation patterns known as convection currents in the atmosphere, in water, and in the mantle of Earth.

The mantle's convective motions break the lithosphere into plates and move them around the surface of the planet. These plates may move away from, move by, or ... |
Mantle convection is the very slow creep of Earth's solid silicate mantle as convection currents carry heat from the interior to the planet's surface. Types of convection · Creep in the mantle |
This heats the lower mantle, causing the magma to become less dense and rise. Once it reaches the upper mantle it cools, becomes more dense and sinks. This ... |
Videolar Magma is the molten rock below the crust, in the mantle. Tremendous heat and pressure within the earth cause the hot magma to flow in convection currents. These ... |
As the core heats the bottom layer of mantle material, particles move more rapidly, decreasing its density and causing it to rise. |
Mantle convection is characterized by rising hot mantle material and sinking colder material, forming convection currents. It is the primary driver of plate ... |
24 мар. 2022 г. · While the mantle material remains solid, the heat and pressure allow convection currents to move the mantle material. (See Resources for a ... |
Heated mantle material is shown rising from deep inside the mantle, while cooler mantle material sinks, creating a convection current. It is thought that this ... |
