Replacement electrons for chlorophyll are generated by splitting

Hydrolysis

Explanation:

In short, this is the work of water splitting in which hydrogen and oxygen are separated. Then the hydrogen atoms that have been generated by hydrolysis give their electrons to the chlorophyll whereas the oxygen molecules are released into the atmosphere.

the speed increase from w to x due to increased gravity force

the speed decreases from x to y due to decrease in gravity

imagine a line passing through the center of earth that goes through both the north pole and the south pole. this imaginary line is called an axis. earth spins around its axis, just as a top spins around its spindle. this spinning movement is called earth's rotation. at the same time that the earth spins on its axis, it also orbits, or revolves around the sun. this movement is called revolution.
