What happens with the temperature as you move upwards through the atmosphere?
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.”
How does the temperature change with altitude in the troposphere?
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.
What happens to pressure as you move up in the troposphere?
Air Pressure and You Air pressure drops about 3.5 millibars per 30 meters (100 feet) as altitude increases. This drop is more pronounced if the air is cold because cold air is denser than warm air. A millibar is a unit of measure that’s equivalent to about 0.0145 pounds per square inch.
How does air change as you move up in altitude through the troposphere quizlet?
The temperature decreases with increasing altitude in the troposphere because these air molecules are heated by the radiation and conduction of energy from Earth’s surface and therefore air molecules closer to the surface have higher temperatures than molecules further from the surface.
What is the air pressure in the troposphere?
Troposphere thickness is about 8 km above the two poles and 18 km at the equator so, average troposphere thickness = (8+18 / 2) = 13 km. The atmospheric pressure in this layer decreases as we go up until it becomes 100 Mb nearly at its top 100 Mb = 0.1 bar (0.1 of the normal atmospheric pressure at sea level).
Why does the troposphere vary in thickness?
The thickness of the troposphere varies around the planet. Near the equator, the troposphere is thicker than at the poles, since the spinning of the Earth tends to shift air towards the equator. The thickness of the troposphere also varies with season.
What is the temperature range of the troposphere?
At middle latitudes, tropospheric temperatures decrease from an average of 15°C (59° F) at sea level to about −55°C (−67° F) at the tropopause. At the poles, the tropospheric temperature only decreases from an average of 0°C (32° F) at sea level to about −45°C (−49° F) at the tropopause.
