State the relationship between altitude and air pressure
Question
State the relationship between altitude and air pressure
Solution
The relationship between altitude and air pressure is inversely proportional. This means that as altitude increases, air pressure decreases.
Here are the steps to understand this relationship:
-
At sea level, the air pressure is highest. This is because the weight of the air above this point is at its maximum.
-
As we ascend or go higher in altitude, say up a mountain or in an airplane, the air pressure decreases. This is because the weight of the air above decreases as we go higher.
-
The air at higher altitudes is less dense, meaning there are fewer air molecules to exert pressure.
-
This is why it's harder to breathe at higher altitudes, because there is less oxygen available due to the lower air pressure.
-
In summary, the higher the altitude, the lower the air pressure.
