The atmosphere does extend out more than 100 miles. The altitude of 100 kilometers (62 miles) is officially the edge of space, but this "boundary" is rather arbitrary.

Where does the earths atmosphere stop?

If you travel some 12. 5 miles into the sky, you will leave roughly 99 percent of the atmosphere behind. At 30 miles up, the density of the atmosphere is roughly one million times less than at the surface.


Is earths atmosphere much thinner and less dense than mercury's?

No


What layer of the earths atmosphere is closet to earths surface?

The lowest is the troposphere, which is the layer that provides most of our weather. It contains about 80% of the Earth's air, but extends only to a height of about 11 miles (17 kilometers) at the Equator and less at the Poles.


Is oxygen found more in the earth's atmosphere more than argon?

Yes, the earths atmosphere has around 20% oxygen, but less than 1% argon.


What effects the layering of earths atmosphere?

the density and temperature of the layers. The farther you go up, the less dense each layer is.


Which makes up less than 1 percent of earths atmosphere?

Argon and trace gases like neon, helium, and methane make up less than 1 percent of Earth's atmosphere.


How does the atmosphere change when you go to high in an airplane?

The air becomes less dense, the higher you go. And generally, the temperature gets colder until you reach the thermosphere, which is the hottest part of Earths atmosphere.


Is earths atmosphere mostly oxygen and hydrogen?

No, Earth's atmosphere is mostly composed of nitrogen (about 78%) and oxygen (about 21%). Hydrogen makes up a very small fraction of Earth's atmosphere, less than 0.1%.


Which layer of the earths atmosphere contains no wate vapor has an atmosphere pressure less than 1.0 atmosphere and has air temperature that increases wth altitude?

The layer of the Earth's atmosphere that fits this description is the thermosphere. In the thermosphere, there is little to no water vapor, the atmospheric pressure is less than 1.0 atmosphere, and the air temperature increases with altitude due to the absorption of solar radiation.


Where are the 4 most abudantgases in earths atmosphere?

About 78% of the atmosphere is nitrogen, while 20% is oxygen. Argon makes up less than 1%. Depending on the location, water vapor would be the third or fourth most abundant, comprising up to 4% of the atmosphere.


What is the order of earths layers from less dense to most dense?

The outer core, inner core, mantle, crust, water, atmosphere. This is the order from densest to least dense.


What percent of earths water is stored in the atmosphere?

Less than 0.001% of Earth's total water is stored in the atmosphere in the form of water vapor. The majority of Earth's water is found in oceans, followed by glaciers, groundwater, and freshwater lakes and rivers.
