As altitude increases, the amount of gas molecules in the air decreases—the air becomes less dense than air nearer to sea level. ... Air expands as it rises, and the fewer gas molecules—including nitrogen, oxygen, and carbon dioxide—have fewer chances to bump into each other. The human body reacts to high altitudes.

What temperature decreases as altitude increases?
In the troposphere, temperatures decrease by an average of 6.5 degrees Celsius per every rise of one thousand meters, which works out to about 3.5 degrees Fahrenheit per thousand feet.
What always increases with increasing altitude?
Temperature increases as you gain altitude in the stratosphere and the thermosphere. Temperature decreases as you gain altitude in the troposphere and mesosphere. Air temperature varies in complicated ways with altitude.
What is the relationship between altitude and temperature?
Temperature varies with altitude, as follows: In the troposphere, temperature decreases as altitude increases. In the stratosphere, temperature generally increases as altitude increases due to the increasing absorption of ultraviolet radiation by the ozone layer.
How does altitude of a place affect the temperature?
As you increase in elevation, there is less air above you thus the pressure decreases. As the pressure decreases, air molecules spread out further (i.e. air expands), and the temperature decreases. If the humidity is at 100 percent (because it's snowing), the temperature decreases more slowly with height.”
Why does temperature increase as the altitude increases?
Temperature in the stratosphere rises with increasing altitude, because the ozone layer absorbs the greater part of the solar ultraviolet radiation. The ozone layer is an absorbing agent that protects life on Earth.
What always decreases with altitude?
Pressure, unlike temperature, always decreases with altitude. In the lower layers of the atmosphere pressure decreases much more rapidly than it does at higher altitudes because density decreases as altitude increases.
Why does wind speed increase with altitude?
Going up in altitude, the pressure gradient between the warm air and the cold air increases with height. ... slow the air as it collides into them. The influence of this friction is less with height above the ground, thus the wind speed increases with height.
What happens to the temperature as altitude increases in the exosphere?
Temperature increases with height and can rise to as high as 3,600°F (2000°C). Nonetheless, the air would feel cold because the hot molecules are so far apart. This layer is known as the upper atmosphere. Exosphere: Extending from the top of the thermosphere to 6200 miles (10,000 km) above the earth is the exosphere.
What happens to air pressure as you change altitude?
As altitude rises, air pressure drops. In other words, if the indicated altitude is high, the air pressure is low. ... As altitude increases, the amount of gas molecules in the air decreases—the air becomes less dense than air nearer to sea level.
Why is the pressure decreases rapidly with altitude?
At higher elevations, there are fewer air molecules above a given surface than a similar surface at lower levels. ... Since most of the atmosphere's molecules are held close to the earth's surface by the force of gravity, air pressure decreases rapidly at first, then more slowly at higher levels.
How does altitude affect precipitation?
Elevation affects precipitation significantly, especially in a mountain environment. On the windward side of a mountain, precipitation is increased. As air parcel rises due to increasing elevation on the windward side of the mountain, the air parcel cools, condenses, and it rains.
How do latitude and altitude affect the climate of India?
Latitude: As the earth is round, sunlight does not reach everywhere equally. The temperature decreases as we move from the equator to the poles. Altitude: As we move from the surface of the earth to the higher altitudes, the temperature decreases. ... Thus, it influences the temperature accordingly.
What happens to density when altitude increases?
Altitude and Density
The density of air decreases with height. There are two reasons: at higher altitudes, there is less air pushing down from above, and gravity is weaker farther from Earth's center. So at higher altitudes, air molecules can spread out more, and air density decreases (Figure below).
When we go to higher altitude then dash decreases?
Pressure with Height: pressure decreases with increasing altitude. The pressure at any level in the atmosphere may be interpreted as the total weight of the air above a unit area at any elevation. At higher elevations, there are fewer air molecules above a given surface than a similar surface at lower levels.
