At one point, there was a single giant landmass known as Pangaea. This supercontinent existed during the late Paleozoic and early Mesozoic eras, approximately 335 to 175 million years ago. Over time, Pangaea began to break apart due to tectonic forces, leading to the formation of the continents we recognize today. The gradual drifting of these landmasses continues to shape Earth's geography.
Red giant - then a white dwarf.
With Earth's mass at about 5.98 x 10^24 kg, it would be Saturn at about 570 x 10^24 kg, with a mass ratio 1:95.18
The center of mass of Earth is located at a point close to its geometric center but shifted slightly towards the side where the heavier mass concentration is. This point is crucial for various calculations in physics and astronomy.
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!).
The center of mass of the Earth-Moon system, also known as the barycenter, is the point around which the two bodies orbit each other. This point is located approximately 4,600 kilometers from the center of the Earth, which is inside the Earth itself, given that the Earth has a much larger mass than the Moon. The barycenter moves in response to the gravitational interactions between the Earth and Moon, but it remains relatively close to the Earth's center due to the significant mass difference.
Pangaea.
What do you mean with "land mass"? Neptune doesn't have continents like Earth. It is a gas giant - made up mainly of gas.
The geometric center and the center of mass of the Earth are essentially the same point.
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.

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.

If Neptune had a solid surface, it would have slightly more gravity at that point than on the surface of the Earth. But it is a gas giant, with a deep atmosphere that becomes crushingly dense and incredibly hot as you near the rocky core. At the point where the atmospheric pressure is equal to the sea level pressure of Earth, the gravitational attraction is about 14% more than on Earth, and the associated acceleration would be about 12% more. Neptune has 17 times the mass of Earth, but the location of this measurement is more than 20,000 km from its center, and gravity decreases as you move farther from the center of mass.
