WebThe theory of plate tectonics explains processes in the geosphere that are fueled by Earth’s internal heat that have operated over billions of years. These changes can be … WebIn fact, the mechanisms by which plate tectonics work are actually poorly understood and research is ongoing. Measurements of temperature from bore-holes and mines tell us that the temperature of the earth increases with depth by an average of two or three degrees Celsius per 100 meters. The source of this heat is radioactivity in the planets core.
WebMay 6, 2024 · Plates of lithosphere move because of convection currents in the mantle. One type of motion is produced by seafloor spreading.

This was the …
WebThis apparent fit is due to the fact the continents were once connected, and have since moved apart in what has been called continental drift. However, we now know that it is not just the continents that move, so a more correct term is plate tectonics. We can credit Alfred Wegener (Figure 4.1. 1) as the originator of this idea.
