How does atmospheric pressure change with altitude? 1. increase 2. decrease 3. does not change 4. increase or decrease depending on the weather
Understand the Problem
The question is asking how atmospheric pressure varies as one moves to higher altitudes. It is seeking an explanation regarding the behavior of pressure in relation to elevation, which is a concept often discussed in physics and meteorology.
Answer
Decrease.
The final answer is decrease.
Answer for screen readers
The final answer is decrease.
More Information
Atmospheric pressure decreases with altitude because there is less air mass above the point of measurement and the air molecules are more spread out at higher elevations. This results in a lower density of air and thus lower pressure.
Tips
A common mistake is to think that atmospheric pressure either increases or remains constant with altitude, but it actually decreases as altitude increases.
