Such convection currents primarily move … Web7 jul. 2024 · Convection is the circulation (and mixing) of gases or liquid. On earth, this happens in air (which causes our weather), and in ocean currents. If for some reason convection stopped, air would not circulate, and weather would stop. Air wouldn’t flow over the waters, suck up moisture and then rain it out on land.

Quick Answer: What Layer Does Mantle Convection Occur

WebGeologists have hypothesized that the movement of tectonic plates is related to convection currents in the earth’s mantle. C 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. WebConvection currents in the Earth occur in the mantle. What gives convection its heat? Convection heating is derived from the transfer of heat by the movement of liquids or gases between surfaces.
