Heating mantles are preferred to Bunsen burners or hot plates for organic liquids. They provide even heating (no hot spots) and maximum surface coverage for better temperature uniformity. Glas-Col ...

Eight major plates are named on the diagram below. Heat from the core makes magma in the mantle rise towards the crust. As the hot current nears the crust, it begins to cool and sink back towards ...

This movement is driven by the very slow creeping motion of Earth's mantle, called convection, which carry heat ... plates collide at Earth's surface, one gives way and sinks into the hot mantle ...
