Why is there more air pressure in the first layer of atmosphere?
The atmosphere consists of 5 layers: the troposphere, which we live in; followed by stratosphere, mesosphere, thermosphere and exosphere. Air pressure at any of these layers is typically caused by hydrostatic pressure, defined as P = hpg, where P is the pressure, h is the height or depth of fluid, and g is the gravitational acceleration. In simple context, my physics lecturer once explained to me: the reason why we live under an atmospheric pressure of 1 bar is simply because there is a column of air above us. As we move upwards (e.g. in an airplane or on top of a mountain), the height of this column is reduced, thus the atmospheric pressure is less. Therefore, the first layer of atmosphere (or the lowest layer) will experience the highest air pressure.
Hot air balloon is flown in which layer of the atmosphere?
Hot air balloons typically fly in the layer of the atmosphere known as the troposphere. The troposphere is the lowest layer of the atmosphere, extending from the Earth's surface up to about 10-15 kilometers (6-9 miles) in altitude.
Can a hot air balloon leave earths atmosphere?
No, a hot air balloon cannot leave Earth's atmosphere. Hot air balloons rely on the Earth's atmosphere to provide lift for their flight. They are designed to operate within the troposphere, the lowest layer of Earth's atmosphere.
In which layer of the atmosphere is air the thinnest?
The thinnest layer of the atmosphere is Exosphere.
Which layer of the atmosphere has the most air?
The troposphere is the layer of the atmosphere that contains the most air, as it is the lowest layer where most weather phenomena occur and a majority of Earth's atmospheric gases are concentrated.
What layer has the lowest air pressure?
The layer with the lowest air pressure is the exosphere, which is the outermost layer of the Earth's atmosphere. It extends from about 500 km to 10,000 km above the Earth's surface and contains very few gas particles.
Which layer in the atmosphere has the most air pressure?
The layer in the atmosphere that has the most air pressure is the troposphere, which is the lowest layer where most weather phenomena occur. As you go higher in the atmosphere, the air pressure decreases.
Which atmospheric layer has the greatest air pressure?
It's the troposphere because :The troposphere contains 75 per cent of the atmosphere's gas. It also holds huge amounts of dust and water vapor, and is often dense with clouds and mist. Air pressure is greatest in the troposphere, because gravity pulls the atmosphere towards the Earth, squeezing most of its weight into this lowest layer.
Which layer of the atmosphere has the lowest air pressure?
http://www.windows.ucar.edu/tour/link=/earth/Atmosphere/layers.html Exosphere That's the outer most layer in the atmosphere. It experiences very low pressures due to the weak gravity at such astronomically high altitudes, and thus the more massive and heavy gases are in levels of the atmosphere, such as the Troposphere.
What layer is the pressure the highest?
The troposphere is the layer of the earth's atmosphere with the highest air pressure.
Which layer of the atmosphere has the least amount of air pressure?
The layer of the atmosphere with the least amount of air pressure is the exosphere, which is the outermost layer of Earth's atmosphere. It is composed of very thin air molecules spread far apart, resulting in extremely low air pressure.
What is the lowest most dense layer in the atmosphere?
The lowest and most dense layer of the Earth's atmosphere is the troposphere. It extends from the Earth's surface up to an average altitude of about 11 km (7 miles) at the poles and 17 km (11 miles) at the equator. It contains about 75% of the atmosphere's total mass.
What layer The air pressure is the greatest here?
The layer where air pressure is the greatest is the troposphere. This is the lowest layer of Earth's atmosphere, extending from the surface up to about 8 to 15 kilometers (5 to 9 miles) high, depending on the location and weather conditions. As altitude increases, air pressure decreases, making the troposphere the region with the highest density of air molecules and therefore the highest pressure.
What layer is the atmosphere pressure highest?
The troposphere is the layer of the earth's atmosphere with the highest air pressure.
Why is the air pressure in the troposphere greater with lower elevation?
Air pressure decreases with higher elevation due to the weight of the air column above pushing down. The air at lower elevations has more air above it, creating higher pressure. This is why air pressure decreases as you go higher in the atmosphere.
Layer of the atmosphere in which humans live is the?
The layer of the atmosphere in which humans live is called the troposphere. It is the lowest layer of the atmosphere and is where weather events occur, as well as where most of Earth's air mass is concentrated.
Which of the following parts of the atmosphere contains the lowest air pressure?
The higher parts
