How is a convection current formed
WebExplain how convection currents are produced in the air. A Type of Heat Transfer: There are three main processes by which heat is transferred: radiation, conduction and convection.... Web24 mrt. 2024 · Convection currents in Earth’s mantle are caused by the rise of hot material rising towards the crust, becoming cooler and sinking back down. This process occurs repeatedly, causing the currents to constantly flow. The movement of the currents plays a factor in the movement of the mantle.

Web2 feb. 2016 · Convection currents are an important form of heat transfer. Convection occurs when heat cannot efficiently be transferred through radiation or thermal conduction. In astronomy convection currents … WebConvection currents are identified in Earth's mantle. 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 type of current is responsible for the movements of the plates of Earth's crust.
