That depends on your definition of "atmosphere".the breathable atmosphere is perhaps 3 to 4 miles thick.the base of the stratosphere is perhaps 6 to 12 miles up.the base of the ionosphere is perhaps 30 to 50 miles up.the boundary of the atmosphere with the vacuum of space is perhaps 250 to 350 miles up.some atmosphere may sometimes be detectable perhaps 1000 miles up, but at this distance the solar wind blows much of it away.
The study of the atmosphere is called atmospheric science, which is divided into two fields: meteorology and climatology. Meteorology studies the short-term behavior of weather, such as a single storm or a single season. Climatology deals with how the atmosphere behaves over long periods of time, usually decades or longer.
Two things the earth atmosphere keeps out are: Harmful radiation and Space debris
Only Mercury has no atmosphere, because of the solar radiation from the sun is so strong where it is.
The condition of the atmosphere at a certain time and place is called weather. Weather includes variables such as temperature, moisture, wind velocity, and barometric pressure. Because the atmosphere is constantly changing, and no two areas are exactly alike, there can be vast weather differences across the globe. Climate is the condition of an area over time.
Over 99% of the mass of the earth's atmosphere is contained in two layers: the troposphere and the stratosphere. Most of the earth's atmosphere (80 to 90%) is found in the troposphere, the atmospheric layer where we live. This layer, where the earth's weather occurs, is within about 12 km (7 miles) of the earth's surface.
1/5 x 2 = 0.4 miles.

Over two miles
what are the two main components of the atmosphere
The Melbourne cup is run over 3200 metres, which is just under two miles.
Just over two hours
The Ozone layer in the upper Atmosphere protects the Earth from over exposure to UV. The entire Atmosphere protects the Earth from meteors by creating FRICTION on high speed objects entering from outer space. The heat of the Friction burns up meteors. These two protective devices are two different mechanisms.
If it goes over two miles an hour it dies
It was 1 mile long and two miles high. Sources: I was there
Just under 80% of the Earth's atmosphere is made up of Nitrogen and just over 20% is made up of Oxygen.
A little over two miles.
