How are convection currents related to plate tectonics?

Convection currents and plate tectonics are related because convection currents are believed to be the main driving force behind the movement of plate tectonics. The mantle, which is located between the Earth's crust and core, contains semi-molten rock called magma. The mantle's solid-liquid state makes it very dense and allows the plates to float on it, similar to how oil floats on water. Convection currents occur in the mantle due to the very hot magma at the deepest part of the mantle rising to the top, cooling down, and sinking again. This process creates a continuous cycle of heating and cooling, causing the plates to move along the Earth's surface. The movement of the plates can lead to a variety of geological events, including earthquakes, volcanic eruptions, and the formation of mountains. Therefore, convection currents are an essential part of the theory of plate tectonics. It is through the ongoing movement of the Earth's plates driven by convection currents in the mantle that shape the Earth's surface.
