What part of Earth contains the air we breathe?

Beginning at the surface of Earth, the troposphere extends to around seven miles up. This is the layer we live in and contains most of what we consider to be "the atmosphere," including the air we breathe and nearly all of the weather and clouds we see.

Does the atmosphere contain the air we breathe?

The blanket of gases that surrounds our home planet not only contains the air that we breathe but also protects us from blasts of heat and radiation emanating from the sun. ... Earth's atmosphere is about 300 miles (480 kilometers) thick, but most of it is within 10 miles (16 km) of the surface.

Can you breathe in the troposphere?

Layers of the Earth's Atmosphere

The troposphere is where weather occurs. You breathe the air in the troposphere. Many airplanes fly in the stratosphere because it is very stable.

What is the air we breathe?

The majority of the air we breathe is made up of nitrogen and oxygen, though you'll also find argon, carbon dioxide and other gases in trace amounts.

What is the name of the air we breathe out?

When we take a breath, we pull air into our lungs that contains mostly nitrogen and oxygen. When we exhale, we breathe out mostly carbon dioxide.

What does the tropopause do?

The tropopause is the boundary that demarcates the troposphere from the stratosphere, and is the part of the atmosphere where there occurs an abrupt change in the environmental lapse rate (ELR), from a positive rate in the troposphere to a negative rate in the stratosphere.

Can we breathe in mesosphere?

The middle layer

The mesosphere lies between the thermosphere and the stratosphere. ... The mesosphere is 22 miles (35 kilometers) thick. The air is still thin, so you wouldn't be able to breathe up in the mesosphere. But there is more gas in this layer than there is out in the thermosphere.

What do you mean by tropopause?

Definition. The tropopause is the upper limit of the troposphere and therefore constitutes the boundary between it and the Stratosphere. ... This second tropopause may be either within or above the 1 km layer. Near the mid-latitudes there may be two layers of tropopauses: polar and tropical.

What produces the air we breathe?

That's right—more than half of the oxygen you breathe comes from marine photosynthesizers , like phytoplankton and seaweed. Both use carbon dioxide, water and energy from the sun to make food for themselves, releasing oxygen in the process.

What creates the air we breathe?

The other key factor in the creation of the air around us is photosynthesis – the process through which plants live, and in which carbon dioxide is extracted from the atmosphere to be replaced with oxygen. Fact: Plants and trees play a vital role in producing the oxygen in the air we breathe.

Does the air we breathe out contain oxygen?

When we exhale, the composition of the air remains almost the same as the air we inhale, only the percentage of carbon dioxide and oxygen changes. The amount of inhaled air contains 21% of oxygen and 0.04% of carbon dioxide, while the air we breathe out contains 16.4% of oxygen and 4.4% of carbon dioxide.

Which gases are in the air we breathe?

Air is mostly gas

The air in Earth's atmosphere is made up of approximately 78 percent nitrogen and 21 percent oxygen. Air also has small amounts of lots of other gases, too, such as carbon dioxide, neon, and hydrogen.

What is troposphere and tropopause?

The troposphere is the lowest and thickest layer of the atmosphere. ... The tropopause is the boundary layer between the troposphere and the stratosphere . The thickness of the troposphere depends upon a number of atmospheric variables at latitude .

Where is troposphere located?

The troposphere is by far the wettest layer of the atmosphere; all of the layers above contain very little moisture. The bottom of the troposphere is at Earth's surface. The troposphere extends upward to about 10 km (6.2 miles or about 33,000 feet) above sea level.

What is the situation in the troposphere defined as unstable?

Air in the troposphere is considered unstable on average because the air temperature tends to decrease with height, and warm air rises.

What is in the troposphere?

The air is densest in this lowest layer. In fact, the troposphere contains three-quarters of the mass of the entire atmosphere. The air here is 78% nitrogen and 21% oxygen. The last 1% is made of argon, water vapor, and carbon dioxide.

Can oxygen be found beyond Mesopause?

Earth as a Planet

As is the case for ozone in Earth's stratosphere, above the mesopause, atomic and molecular oxygen strongly absorb solar UV radiation and heat the atmosphere. ... At about 120 km, molecular diffusion becomes more important than turbulent mixing, and this altitude is called the homopause (or turbopause).

What layer do planes fly?

Commercial jet aircraft fly in the lower stratosphere to avoid the turbulence which is common in the troposphere below. The stratosphere is very dry; air there contains little water vapor. Because of this, few clouds are found in this layer; almost all clouds occur in the lower, more humid troposphere.
