In the simplest terms, the atmosphere is gaseous. Gas expands infinitely unless contained by a solid, until it event dissipates. While the atmosphere is a continuous concentration of gas, it is very difficult to define its absolute top.
The closer you are to the edge of the atmosphere, the denser air gets. That's why mountain climbers find it difficult to breathe, as there is less oxygen in the air up there.
The "Surface" of Jupiter is hard to define as it is a gas giant but the top of the atmosphere (however you want ti define that) is cold due to heat radiating into space. Jupiter is so much farther from the Sun than Earth is, the Sun cannot heat Jupiter's atmosphere. And the heat form the interior (it is actually hotter than the surface of the Sun deep inside Jupiter!) dissipates into space.
The stratosphere which contains most of the atmosphere's ozone.
The top 2 are nitrogen and oxygen.
This is due to the thinness of the atmosphere at high altitudes (e.g. the top of a mountain). The thinness is caused by the loss of molecules to space due to the slight lessening of gravity's pull at high altitudes.
define top and define your definition of best.

You can usually see the atmosphere clearly during the day time. And, only if you are on top of a high surface, such as a mountain top.
the air gets thinner as you get nearer the top.
The top layer of Earth's atmosphere is called the exosphere. It is the outermost layer where the atmosphere transitions into space. The exosphere is very thin and composed mostly of low-density gases.
In an improper fraction the absolute value of the numerator (the top) is bigger than the absolute value of the denominator. An improper fraction is also called a top-heavy fraction.
You're born.
The troposphere is the portion of the atmosphere closest to earth. It is below the stratosphere.
The troposphere is the portion of the atmosphere closest to earth. It is below the stratosphere.
If you're talking about the thinnest layer of the atmosphere, then it is the EXOSPHERE..
The numerator is the top number; the denominator is the bottom number.
