In which layer of earth do convection currents occur

1 answer

Convection currents primarily occur in the mantle of the Earth. The mantle is located between the Earth's crust and the outer core and is composed of semi-solid rock that can flow slowly over time. These convection currents are driven by the heat from the Earth's core, causing the mantle material to rise, cool, and then sink again, creating a continuous cycle. This process is a key driver of plate tectonics and contributes to various geological phenomena, such as earthquakes and volcanic activity.
