earth core
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!).
Since the atmosphere is more or less symmetric, its center of mass (center of gravity) gravity must be quite close to Earth's center.
The distance from the center of mass to Earth, times the mass of the Earth, must be equal to the distance of the center of mass to the Moon, times the mass of the Moon. (For more than 2 objects, the calculation is somewhat more complicated - reading about "center of mass" can give you an idea.)The distance from the center of mass to Earth, times the mass of the Earth, must be equal to the distance of the center of mass to the Moon, times the mass of the Moon.

It lies at the center of the Earth.

the center of the earth
The center of mass of Earth's atmosphere is located close to Earth's geometric center, but it can be slightly influenced by atmospheric circulation patterns and mass distribution. Overall, it is within the region of Earth's core, beneath the crust and atmosphere.
Assuming that the atmosphere is distributed evenly all over the Earth, its center of mass is of course at the Earth's center. If for any reason there is more atmosphere on one side than on the other, the center of mass would be slightly away from Earth's center.
Since the atmosphere is more or less symmetric, its center of mass (center of gravity) gravity must be quite close to Earth's center.
The mass at the center of the Earth is found at the Earth's core.
The geometric center and the center of mass of the Earth are essentially the same point.
The percentage of oxygen in the Earth's atmosphere by mass is approximately 21.
The mass that surrounds Earth is the atmosphere. The average of Earth's atmosphere is 5 quadrillions tons. I think that answered you question.
The mass at the center of the Earth is estimated to be about 6.37 x 1024 kilograms.
The distance from the center of mass to Earth, times the mass of the Earth, must be equal to the distance of the center of mass to the Moon, times the mass of the Moon.

The mass located at the center of the Earth is the Earth's core, which is primarily made up of iron and nickel.
