Assuming that the Earth's atmosphere is a perfect sphere, then the atmosphere's center of mass will be at the point equidistant between Earth's poles (i.e. the center of the Earth!).
Red giant - then a white dwarf.
Correct
This is clearly related to its greater mass. The other giant planets also have several moons each.
Your mass remains the same no matter where you are. (It does vary with velocity, however, at relativistic speed). Jupiter is a gas giant and does not have a proper "surface." If we could agree that at some point the gas would be sufficiently dense to constitute a "surface," your WEIGHT at that point would be 2.5 times that of your weight at earth's surface.
Pangaea.
The geometric center and the center of mass of the Earth are essentially the same point.
Pangea was a supercontinent that contained every modern-day continent, so there was basically just one giant landmass. Pangea is Greek for 'Entire Earth'.
the mass of a red giant is 300 asses
Yes air has mass. It is the mass of the air above a point on earth that is responsible for the air pressure.

What do you mean with "land mass"? Neptune doesn't have continents like Earth. It is a gas giant - made up mainly of gas.
Correct
Basically true - except for a tiny change in mass, due to the General Theory of Relativity. However, this change in mass only applies from the point of view of somebody who stays on Earth, for example.Basically true - except for a tiny change in mass, due to the General Theory of Relativity.

One kilogram. Mass is invariant.The weight at that point is zero. But the mass doesn't change.
Just move the decimal point to the right until the exponent is 15! mass of Earth = 5.9742 × 10^24 kilograms 5,974,200,000 quadrillion kilograms.
