What is the air pressure in the troposphere?
The air pressure is roughly 1000 mb at sea level, 500 mb at 5.5 km above sea level, 250 mb at 11 km above sea level, 125 mb at 16.5 km above sea level, and so forth. The figure above also shows that on average the top of the troposphere is located at a pressure of about 250 mb.

What is the air pressure in mesosphere?
The average air pressure of the mesosphere is only 0.01 mb (or hPa), which is just 1/100,000 that of the surface air pressure. Air pressure decreases exponentially with height, so 99.9% of the atmosphere’s mass is below the mesosphere.

What is the air pressure in atmosphere layers?
At sea level, air pressure is about 14.7 pounds per square inch (1 kilogram per square centimeter), and the atmosphere is relatively dense. At 10,000 feet (3 km), the air pressure is 10 pounds per square inch (0.7 kg per square cm), which means molecules of gas that make up the atmosphere are less dense.

What is the air pressure in thermosphere?
The pressure at the base of the thermosphere is about 0.01 mb or (hPa), whereas at Earth’s surface it averages 1005 hPa. The pressure continues to drop with altitude in the thermosphere, and is nearly zero at its top.

What is the air pressure of the mesopause?
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).

What is the air pressure in 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).

Does air pressure increase in the troposphere?
Answer and Explanation: Air pressure decreases with height in the troposphere in an exponential relationship. This is because gravity also decreases with height exponentially, and the atmosphere is held in place by gravity.

What happens to air pressure in each layer of the atmosphere?
On average in Earth’s atmosphere, the air pressure approximately drops in half for every 5.5 km increase in altitude. The air pressure is roughly 1000 mb at sea level, 500 mb at 5.5 km above sea level, 250 mb at 11 km above sea level, 125 mb at 16.5 km above sea level, and so forth.

Which atmosphere layer has the highest air pressure?
The air density in the atmosphere decreases as we travel higher in altitude. The air pressure in the atmosphere is greatest in the troposphere.

How does air pressure differ in the layers of the atmosphere?
Air pressure and density work and change together as you enter different layers of the atmosphere. 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.
