WebSep 12, 2024 · Convection currents are flowing fluid that is moving because there is a temperature or density difference within the material. Because particles within a solid are fixed in place, convection currents are seen only in gases and liquids. A temperature difference leads to an energy transfer from an area of higher energy to one of lower energy. WebMay 19, 2024 · The material in the mantle of Earth moves in a convection current. As thermal energy from the core heats the mantle, the molten material rises toward the crust, where it will begin to cool....
WebThe mechanism by which tectonic plates move is still a subject of much debate among Earth scientists. The Earth is dynamic thanks to its internal heat, which comes from deep within the mantle from the breakdown of radioactive isotopes. It was long thought that this resulted in convection currents in the mantle which were responsible for the ... WebJan 18, 2010 · Best Answer.
