When the oxygen level of the atmosphere drops below 17 percent, it can lead to hypoxia, a condition where the body does not receive enough oxygen to function properly. Symptoms may include shortness of breath, confusion, and impaired cognitive function. Prolonged exposure to such low oxygen levels can result in unconsciousness or even death, as vital organs begin to fail due to insufficient oxygen supply. Normal atmospheric oxygen levels are around 21 percent, and any significant drop can pose serious health risks.

Is true About 99 Percent Of The Earth's Atmosphere Is Below An Altitude Of 30 Km?
Yes, it is true that about 99 percent of the Earth's atmosphere is contained within the first 30 kilometers (approximately 18.6 miles) above sea level. The majority of the atmosphere's mass is concentrated in the lower troposphere, where weather occurs and most of the air we breathe is located. Above this altitude, the atmospheric density decreases significantly, making it less dense and less significant in terms of the overall mass of the atmosphere.
What is below the thermosphere?
Below the thermosphere are the mesosphere, stratosphere, and troposphere. The mesosphere is the layer of the atmosphere above the stratosphere and below the thermosphere. The stratosphere is above the troposphere and below the mesosphere, and the troposphere is the lowest layer of the Earth's atmosphere.
What fraction of the atmosphere's mass is below an aircraft flying at the 700 mb level?
The 700 mb level of the atmosphere is 10,000 feet in the air. This level is the second level used for measuring the atmosphere in the troposphere, so 1/5 of the atmosphere is located below it.
What type of cloud is below 6500 feet in the atmosphere?
Alto
What is the main gas in the mesosphere?
The main gas in the mesosphere is nitrogen, which makes up about 78% of the atmosphere. Oxygen is also present, constituting about 21%. In this layer of the atmosphere, both gases are found in lower densities compared to the layers below. The mesosphere extends from approximately 50 to 85 kilometers above the Earth's surface.
What is the minimum amount of oxygen needed to sustain fire in the atmosphere?
The minimum amount of oxygen needed to sustain a fire in the atmosphere is about 16% oxygen. Below this level, the fire would not have enough oxygen to continue burning.
In what part of the atmosphere does life occur?
Life occurs in the troposphere. It is the lower most level of the atmosphere and is the region below 12 km.
50 percent of the gases that make up the atmosphere are found below?
50 percent of the gases in Earth's atmosphere are found below an altitude of about 5.6 kilometers, or 18,000 feet. This part of the atmosphere is known as the troposphere and contains most of the weather and breathable air.
Almost 90 percent of the atmosphere's total mass is contained in the?
Almost 90 percent of the atmosphere's total mass is contained below 16 km. 99.999percent is below 100 km which is the Karman Line the demarcation which marks the beginning of space.
What would it indicate if an individual had oxygen saturation of below 90 percent?
An oxygen saturation below 90 percent would indicate that the individual is not getting enough oxygen into their bloodstream. This could be a sign of respiratory issues or other health problems that need immediate attention.
What fifty percent of the gases that make up the atmosphere are found below what?
Fifty percent of the gases that make up the atmosphere are found below the altitude of about 5.6 kilometers (18,000 feet). This is also known as the tropopause, which is the boundary between the troposphere and the stratosphere.
What is the concentration of oxygen in air exhaled?
There is 13-16% oxygen in expired air but it depends on your size. See the link below.
50 percent of gases that make up are atmosphere are found below?
50 percent of the gases that make up Earth's atmosphere are found below about 5.6 kilometers (3.5 miles) in altitude, which is roughly half of the total atmosphere's height. This portion of the atmosphere is known as the troposphere, where most weather phenomena and aircraft travel occur.
Which of the following choices describes an oxygen deficient atmosphere?
An oxygen deficient atmosphere is one that lacks a sufficient amount of oxygen to support human or animal life. It can occur in environments where oxygen is depleted, such as in confined spaces or areas with high levels of carbon dioxide, gases, or chemicals that displace oxygen. Breathing in an oxygen deficient atmosphere can lead to suffocation or loss of consciousness.
Is true About 99 Percent Of The Earth's Atmosphere Is Below An Altitude Of 30 Km?
Yes, it is true that about 99 percent of the Earth's atmosphere is contained within the first 30 kilometers (approximately 18.6 miles) above sea level. The majority of the atmosphere's mass is concentrated in the lower troposphere, where weather occurs and most of the air we breathe is located. Above this altitude, the atmospheric density decreases significantly, making it less dense and less significant in terms of the overall mass of the atmosphere.
What minimum oxygen must be what percentage of the atmosphere to sustain the burning process?
Oxygen must be at least 16% of the atmosphere to sustain the burning process. Below this level, fires may not be able to burn efficiently or sustain themselves.
Does it sleet in the winter?
Sleet requires temperatures to be below freezing in the lower part of the atmosphere and at the surface, so yes, it occurs in the winter.
