Air expands when it rises because of the pressure and temperature. While air rises, there is less compression and pressure on nearby air, so it expands, it's not as tight. Air also takes space. Think of it as units of stuff. People in mountains normally die because of the expanded air which is too thin to breathe, because all the molecules are apart and running away.

What happens to water vapor as it moves upward in the air?

When an object falls freely the kinetic energy of the object will?
It will decrease if the object moves upward; decrease if the object moves downward.
What is a stratospohere?
The stratosphere is a layer of Earth's atmosphere. The stratosphere is the second layer, as one moves upward from Earth's surface, of the atmosphere.

What does peristalisis do?
It breaks down food and moves it through your body. muscles contract and expand
Why does air cool as it moves upward?
Air doesn't necessarily cool as it moves up, generally hotter air is lighter and so moves upward. However in the atmosphere the pressure gradually decreases with altitude, pressure and temperature are state functions and change according to one another. Generally if the pressure decreases (as it does with altitude) the temperature too, decreases.
What is the main way that energy moves through the atmosphere hydrosphere and geosphere?
by force
What happens to warm air as it moves through the atmosphere?
the warm air raises
When a parcel of air moves upward it expands and cools?
When a parcel of air moves upward, it expands and cools due to the altitude.
What muscle moves the scapulae forward and rotate scapula upward?
The Serratus Anterior moves the scapula forward and rotates it upward.
What is the upward force on a wing as it moves through the air?
Perhaps coincidentally, most aeronautical engineers refer to that force as "lift".
What is a meteoric fireball?
bolide A meteor that is burning up as it moves through the earth's atmosphere.
