WebIn this model, plates move through a combination of pull from the weight of the subducting edge of the plates, and through the outward pushing of an ocean ridge where magma is rising and forming new crust (Figure 4.3.2). Figure 4.3.2 Models for plate motion mechanisms (Steven Earle, “Physical Geology”). Some compelling arguments in favor of ... WebSep 30, 2016 · In the ocean, convection caused by heating and cooling helps to drive ocean currents. These currents move water around the globe. Radiation The third type of energy transfer is in some ways the most unusual. It can move through materials — or in the absence of them. This is radiation.

WebSmaller convection currents can be found in a cup of hot cocoa or a fish tank. Convective motions in the atmosphere are responsible for the redistribution of heat from the warm equatorial regions to higher latitudes and from the surface upward. The main three processes of heat transfer include radiation, conduction, and convection. WebMolten material beneath Earth's crust rises to the surface.
