Final answer:
Convection in the Asthenosphere drives plate tectonics, shaping the Earth's crust and causing geological activities. It is not the fuel for the Earth's rotation or gravity.
Step-by-step explanation:
Convection in the Asthenosphere is the process by which heat is transferred within the Earth's mantle. The movement of material in the asthenosphere through convection currents creates the driving force behind plate tectonics. These convection currents cause the lithospheric plates to move, leading to various geological activities such as earthquakes, volcanic eruptions, and the formation of mountain ranges.
This movement is not directly responsible for the Earth's rotation or gravity, but it does play a crucial role in shaping the Earth's crust and influencing the distribution of continents and oceans.
