There is no boundary where Earth's atmosphere is constrained by gravity. Many feel that astronauts orbiting above the Earth are weightless because they are far away from Earth's gravity , but weightlessness is actually caused by the free-falling of an object that is in orbit.
Hydrogen and helium
Moon gravity is less because the atmosphere and mass and the earths gravity is greater than the moon if you weight yourself in the earth and then you weighted yourself in the moon you would weight less in the moon you could actually float in the moon because of its atmosphere and mass
The earths gravity. The more mass a body has, the more gravity, The Earth has enough mass to hold an atmosphere. The Moon, on the other hand, is not massive enough, and so does not have a high enough gravity, which prevents it from holding an atmosphere.
No. To even reduce it by 75% you must travel out to 4000 miles.
Gravity is strongest at the earths surface because it's atmosphere is v dense and so the force inc.this happens because force is directly proportional to density.
magnetosphere.
magnetosphere.
Earths atmosphere? 300 miles. There is no definite boundary.
There is no atmosphere on the moon. There is insufficient gravity to keep an atmosphere there.
Gravity pulled it in.
The two are completely unrelated.
Gravity is a constant not a variable. (stays constant at 9.8ms/s in earths atmosphere)
The Earth's gravity.
It doesn't. Gravity does, not air.
Hydrogen and helium
Gravity.
Exosphere. The layers of the atmosphere are: Space Exosphere Thermosphere Mesosphere Stratosphere Troposphere Earth
