What’s the pressure of the stratosphere?
The pressure in the stratosphere is between 20,000 Pascals or 2.9 psi and 100 Pascals or 0.014 psi.
Is the air pressure high or low in the stratosphere?
The stratopause caps the top of the stratosphere, separating it from the mesosphere near 45–50 km (28–31 miles) in altitude and a pressure of 1 millibar (approximately equal to 0.75 mm of mercury at 0 °C, or 0.03 inch of mercury at 32 °F). In the mesosphere, temperatures again decrease with increasing altitude.
What is the air pressure in troposphere?
The troposphere has the following characteristics. It extends from the earth's surface to an average of 12 km (7 miles). The pressure ranges from 1000 to 200 millibars (29.92 in. to 5.92 in.).
How does air pressure change in the stratosphere?
As the atmosphere expands the further you get from the Earth's surface, it becomes less dense and air pressure decreases. As you increase altitude (distance from Earth's surface) in an airplane, air pressure changes.
What layer has the highest air pressure?
The Troposphere contains about half of all the air in the entire atmosphere. Because it i at the bottom, air pressure, or the weight of the air, is greatest in this layer.
What is the air pressure in the mesosphere?
0.01 millibars This layer is the mesosphere, which at its top (the mesopause) has an atmospheric pressure of only 0.01 millibars (that is, only 1/100,000th of the surface pressure). Above the mesosphere lies the thermosphere, extending hundreds of miles upward toward the vacuum of space.
What is the layer with the lowest air pressure?
- Exosphere.
- The Exosphere has the lowest pressure because pressure drops as altitude increases. This is due to the.
- atmospheric air being pulled towards the surface of the earth due to gravity. …
- up because there is lesser and lesser air mass above you. …
- down pressure goes down too and vice versa.

What altitude is the stratosphere?
The bottom of the stratosphere is around 10 km (6.2 miles or about 33,000 feet) above the ground at middle latitudes. The top of the stratosphere occurs at an altitude of 50 km (31 miles).

What is the pressure of the thermosphere? This is around the 0.005 mb (0.0005 kPa) pressure level.

Where is air pressure lowest in the atmosphere?
The lowest measurable sea-level pressure is found at the centers of tropical cyclones and tornadoes, with a record low of 870 hPa (87 kPa; 26 inHg).

What is the temperature of the stratosphere?
Heat is produced in the process of the formation of Ozone and this heat is responsible for temperature increases from an average -60°F (-51°C) at tropopause to a maximum of about 5°F (-15°C) at the top of the stratosphere. This increase in temperature with height means warmer air is located above cooler air.
Which layer of atmosphere has the most air pressure?
The Troposphere The Troposphere contains about half of all the air in the entire atmosphere. Because it i at the bottom, air pressure, or the weight of the air, is greatest in this layer.
Do planes fly in the stratosphere?
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 and contains little water vapor. Because of this, few clouds are found in this layer and almost all clouds occur in the lower, more humid troposphere.
Can you breathe in stratosphere?
2.1 The Density and Temperature of Air. The stratosphere is not a good place to be. First, the ozone in the stratosphere, which protects us from biologically destructive solar ultraviolet light, exists at such high levels that the air itself is toxic. Second, even this toxic air is much too thin for normal breathing.
Where on Earth has the lowest air pressure?
World: Lowest Sea Level Air Pressure (excluding tornadoes)
| Record Value | 870 hPa |
|---|---|
| Date of Event | 12 / 10 (October) / 1979 |

| Geospatial Location | Pressure Estimated in Eye of Typhoon Tip (16°44'N, 137°46'E) |
Which location has the highest air pressure?
Air pressure is highest at the sea level.

Can birds fly in the stratosphere?
The stratosphere contains roughly 20 percent of the atmosphere's mass. Because bacterial life can survive in the stratosphere, this layer of the atmosphere belongs to the biosphere. Some species of birds have even been reported to fly in the lower levels of the stratosphere.
Can you breathe 30000 feet?
Somewhere between 30,000 and 40,000 feet the pressure around you becomes far too low to push those oxygen molecules across the membranes in your lungs, and you get hypoxic (altitude sickness). If you try to breathe 100 percent oxygen above 40,000 feet for very long without a special type of mask, you'll die.
What is the highest air pressure ever recorded?
1083.8mb The highest barometric pressure ever recorded was 1083.8mb (32 in) at Agata, Siberia, Russia (alt. 262m or 862ft) on 31 December 1968. This pressure corresponds to being at an altitude of nearly 600 m (2,000 ft) below sea level!
