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. WebAnd so we call this process, this is convection. Now, the reason why we think the plates are moving is because we think that there are similar types of convection currents in the asthenosphere, in the mantle, in the more fluid part of the mantle. Remember, most of the mantle you can kind of view it as this mooshy, spongy, not quite liquid, but ...
