Collectively it's called the Atmosphere. There are sub-zones within the atmosphere but collectively it is referred to as the Atmosphere.
Strictly speaking, no such "space barrier" between the Earth's atmosphere and outer space exists; Rather, the atmosphere gradually thins out until it reaches vacuum of space. However, there is an imaginary boundary called the Kármán Line which lies at 62 miles or 100 kilometers above Earth's sea level, and is commonly accepted by scientists as defining the official break between Earth's atmosphere and outer space. The Kármán Line sits near the bottom of the thermosphere and just above the mesosphere, and is also the altitude at which the aurora form. The Line is not always considered the edge of space, however. If one were to include the thermosphere and exosphere as part of the atmosphere and not of space, then the barrier could be placed as high as 6,200 miles or 10,000 kilometers above sea level-that's one hundred times higher than the Kármán Line!
space satellites are in space and earth satellites are in earth.
Hydrogen and helium. :)
"Distance" is defined between TWO objects, or points in space.

The curvature of the Earth is one barrier, and the spinning of the Earth through space is another.

Geographic isolation, where physical barriers prevent gene flow between populations, can cause reproductive isolation. This can lead to genetic differences accumulating over time, ultimately resulting in the development of separate species.
Space shuttles
Astronomy is planets and space earth science is about earth
They are both in space
Nothing. Empty space.
