In convection why does cooler material sink

WebMantle convection is the very slow creeping motion of Earth's solid silicate mantle as convection currents carry heat from the interior to the planet's surface.. The Earth's surface lithosphere rides atop the asthenosphere and the two form the components of the upper mantle.The lithosphere is divided into a number of tectonic plates that are continuously … WebC onvection currents describe the rising, spread, and sinking of gas, liquid, or molten material caused by the application of heat. An example of convection current is shown in Fig. 7.16. Inside a beaker, hot water rises at the point where heat is applied. The hot water moves to the surface, then spreads out and cools.
