I'm not sure what you mean by "a lower source of gravity".
The gravitational force between the Earth and anything else would be less than it
is now if the Earth's mass were smaller than it is. That kind of change would have
no effect on the Earth's daily axial rotation or annual orbital revolution.
radiation & gravity
It is due to the earth's rotation. (source: January 2005 earth science regents exam)
because they have teir own source of gravity and the are out of the earths atmosphere unlike rain drops. stars have built in gravity rain doesnt
Gravity doesnt have a source.
rotation
Mass is the source of Earth's gravity. Any object that has mass has gravity.
Yes.
Gravity is caused by mass. Everything causes gravity but the bigger it is and more mass it has the more pull is felt by its gravity. So you are pulling the earth towards you and the earth is pulling you. The earth is much bigger and has more mass, so it pulls much more. Gravity gets weaker the further away you get from its source. The earths crust does not have the same mass all over, so some areas have slightly less gravity than others. The differences between areas are very very small. The moon has only a quarter the mass of the earth, so gravity on the moon is a quarter of earths gravity.
