what is the last gas between where the earth ends and space begins?

Question

or the "skin" of the earth , what does it comprise of?

Answer 1

Hydrogen, because it has the smallest atomic weight, and being the lightest it floats above everything else.

Answer 2

Littlebigdog is the only one that has anywhere close to the right answer.

The atmosphere is a mixture of many gases, especially N2, O2, and C02. The proportions don't change, it just gets "thinner" - meaning the pressure gets less and less the higher you go. There is no point where the earth ends and space begins, but most scientists would consider space beginning at between about 25 and 75 km above the earth's surface. There is still measurable atmosphere over 100 km.

Answer 3

Earth's Atmosphere
Troposphere Earth's surface and extends 8 to 14.5 kilometers high
Stratosphere just above the troposphere and extends to 50 kilometers (31 miles) high
Mesosphere just above the stratosphere and extends to 85 kilometers (53 miles) high
Thermosphere just above the mesosphere and extends to 600 kilometers (372 miles) high

Beyond the Atmosphere
The exosphere starts at the top to the thermosphere and continues until it merges with interplanetary gases, or space. In this region of the atmosphere, Hydrogen and Helium are the prime components and are only present at extremely low densities.

Answer 4

There is no definite end to the earths atmosphere, it just blends in to the thin soup of all types of elements floating around in space. There are many gases out there that are just really dispersed so there is no specific gas that is the last layer. And no, it is definitely not Ozone. Ozone is in a layer in the stratosphere that has gases on top and below it.

Answer 5

Actually its a mix of several gases incl. helium, hydrogen, various forms of di-oxides (anything with an oxygen atom attached) and nitrogen. See the lightest elements (H1 and H2) are escaping earths gravitational field. The di-oxides Like CO2 and O3 are next in line and then nitrogen followed by simple oxygen. There are also trace ammounts of methane and ammonia in our atmosphere but there quantities are so small you would not even notice.

Answer 6

There is a mixture of gasses at the surface of the earth and that same mixture is at the outer limits but it is not under the same weight or pressure as the gas or air at the surface. There is no difference in the composition at either place but the pressure reading is different.

Answer 7

Farts, it is the collection of millions of years worth of animals bum trumps. Where else do you think it went.

Was originally known as OH ZONE when the first astronaut's got a whiff it.

Answer 8

ther is 5 layers above the earth the last one i thunk is ozon

Answer 9

hydrogen is floating in extreme low concentration on the heavier gasses.

Answer 10
