The Sun
Explanation:
The sun does not move or rotate and hence cannot retrograde, however the other planets rotate. Some astronomers define retrograde motion as the Westward movement of the planets relative to the sun, based on this definition, all the planets experience retrograde movement. On the other hand, while some astronomers define retrograde motion as the movement that the other planets make when earth passes them while orbiting the sun. Based on this second classification, Mercury and Venus do not retrograde relative to the earth because they move faster than the earth.
In the earth’s mantle , large amounts of heat are transferred by convection currents, which would cause the heat from the core and the mantle itself causes convection currents in the mantle . The hot rocks eventually will cool and sink back through the mantle which will make the cycle repeat which would be the cycle of rising and sinking .
Answer: Heat energy.
Explanation: The source of hurricanes is heat energy, which is practically fuel to the storm.
