Why earths atmosphere becomes less dense with increasing altitude above earth?
Earth's atmosphere becomes less dense with increasing altitude due to the gravitational pull of the planet, which holds air molecules closer to the surface. As altitude increases, there are fewer air molecules above to exert pressure, resulting in a decrease in air density. Additionally, the temperature generally decreases with altitude in the troposphere, which can also contribute to the reduction in air density. This combination of factors leads to a thinning atmosphere as one ascends.
Why does Earth's atmosphere become less dense with increasing altitude above Earth?
Earth's atmosphere becomes less dense with increasing altitude due to the decrease in air pressure and the gravitational pull exerted on air molecules. As altitude increases, there are fewer air molecules above a given point, leading to lower pressure and reduced density. Additionally, the temperature can also drop with altitude, which can further contribute to the decrease in air density. This combination of factors results in a thinner atmosphere at higher elevations.
How does air pressure change with altitude in the atmosphere?
Air pressure decreases with increasing altitude in the atmosphere. This is because the weight of the air above decreases as you go higher up, leading to lower air pressure. The rate at which air pressure decreases with altitude is not constant and depends on various factors such as temperature and weather conditions.
In which layer of atmosphere temperature decreases with increasing altitude?
In the Earth's atmosphere, temperature decreases with increasing altitude in the troposphere. This is the lowest layer, where weather phenomena occur, and it extends from the surface up to about 8 to 15 kilometers high, depending on location. As altitude increases, the air becomes less dense, leading to a decrease in temperature. Above the troposphere, in the stratosphere, temperature begins to increase with altitude due to the absorption of ultraviolet radiation by the ozone layer.
What layer of the atmosphere lies between the mesosphere and the exosphere?
The thermosphere is the layer of the atmosphere that lies between the mesosphere and the exosphere. It is characterized by increasing temperatures with altitude and is where the auroras occur.
How the atmosphere vary with altitude?
Temperature decreases with increasing altitude, Also air concentration decreases with altitude.
How can warm air cool off?
in the lower atmosphere the air gets colder with increasing altitude.
How does air pressure vary with altitude?
Air pressure decreases with increasing altitude. This means that as you go higher in the atmosphere, the air pressure becomes lower.
Does the temperature of the atmosphere decrease steadily with increasing altitude?
Yes, the temperature of the atmosphere generally decreases with increasing altitude at a rate of about 6.4°C per kilometer. This is known as the lapse rate and is influenced by factors like the sun's radiation, convection, and the composition of the atmosphere.
Which layer extends to an average altitude of about 12 km?
The troposphere is the layer of the atmosphere that extends to an average altitude of about 12 km. This is where most weather phenomena occur and where temperature generally decreases with increasing altitude.
How does air pressure change with altitude in the atmosphere?
Air pressure decreases with increasing altitude in the atmosphere. This is because the weight of the air above decreases as you go higher up, leading to lower air pressure. The rate at which air pressure decreases with altitude is not constant and depends on various factors such as temperature and weather conditions.

Above the troposphere, in the stratosphere, temperature begins to increase with altitude due to the absorption of ultraviolet radiation by the ozone layer.
As the altitude increases does the barometric pressure increase or decrease?
As altitude increases, barometric pressure decreases. This is because the air pressure decreases with increasing altitude, as there are fewer air molecules in the atmosphere exerting pressure on a given area.
What layer of the atmosphere lies between the mesosphere and the exosphere?
The thermosphere is the layer of the atmosphere that lies between the mesosphere and the exosphere. It is characterized by increasing temperatures with altitude and is where the auroras occur.
What is the name of the lowestlayer of Earth's atmosphere called?
The lowest layer of Earth's atmosphere is called the troposphere. This layer is where weather events occur and temperature decreases with increasing altitude.
How do pressure and temperature vary in the atmosphere?
In the atmosphere, pressure generally decreases with higher altitude due to the decrease in air density. Temperature changes can vary depending on altitude and location, but in general, the temperature decreases with increasing altitude in the troposphere, remains relatively constant in the stratosphere, and then increases in the mesosphere and thermosphere.
How do atmospheric layers differ?
The five layers of the atmosphere have different atmospheric temperature that occurs with increasing altitude. The layers also thin out with height from the surface.
