Final answer:
Atmospheric pressure at sea level is 101.3 kPa, at approximately 560 meters above sea level it is about 85.0 kPa, and at an altitude of 3000 meters, it decreases to 70.0 kPa. The atmospheric pressure decreases as altitude increases, and this relationship is useful for understanding weather patterns and altitude impacts.
Step-by-step explanation:
The relationship between altitude and atmospheric pressure is such that pressure decreases with an increase in altitude. Atmospheric pressure at sea level averages 101.3 kPa, which is equivalent to 1 atmosphere (atm). As you ascend, the atmospheric pressure decreases. At an altitude of approximately 560 meters above sea level, the atmospheric pressure is about 85.0 kPa. At an altitude of 3000 meters, the atmospheric pressure drops to roughly 70.0 kPa.
The complete statements would be:
- 101.3 kPa is about sea level
- 85.0 kPa is about 560 m
- 70.0 kPa is about 3000 m
It's important to note that standard atmospheric pressure can be expressed in various units, including pascals (Pa), kilopascals (kPa), millimeters of mercury (mm Hg), and inches of mercury (in. Hg). Changes in atmospheric pressure can be crucial for weather predictions, such as the approach of a storm, which typically accompanies lower atmospheric pressures.
