WebHolmes 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. … WebIn 1929, about the time Wegener's ideas began to be dismissed, Arthur Holmes elaborated on one of Wegener's many hypotheses; the idea that the mantle undergoes thermal convection. This idea is based on the fact that as a liquid is heated its density decreases — this less-dense liquid rises to the surface until it is cooled and sinks again.
