Detailed explanation-1: -Holmes theorized that convection currents move through the mantle the same way heated air circulates through a room, and radically reshape the Earth’s surface in the process.
Detailed explanation-2: -Convectional Current Theory was given by Arthur Holmes in the 1930s. It discussed the possibility of convection currents operating in the mantle portion These currents are generated due to radioactive elements causing thermal differences in the mantle portion.
Detailed explanation-3: -Convection 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.
