Consider the following statements: 1. The air pressure is highest at ...
Explanation:
Statement 1: The air pressure is highest at sea level and decreases with height.
This statement is correct. The air pressure at sea level is the weight of the air above a unit area at sea level. As we move up in the atmosphere, the weight of the air decreases, and hence, the air pressure also decreases. Thus, air pressure is highest at sea level and decreases with height.
Statement 2: Low air pressure is generally associated with cloudy skies and wet weather.
This statement is also correct. Low air pressure is associated with unstable weather conditions and the formation of clouds. When the air pressure is low, the air rises, cools, and condenses to form clouds. The condensation of water vapor in the air leads to the formation of precipitation, which can result in wet weather.
Conclusion:
Both statements 1 and 2 are correct. The air pressure is highest at sea level and decreases with height. Low air pressure is associated with unstable weather conditions and the formation of clouds, which can lead to wet weather.
Consider the following statements: 1. The air pressure is highest at ...
- When the temperature is high in the area, the air gets heated and rises, which creates a low-pressure area. Cloudy skies and wet weather are due to low pressure.
- In lower temperature areas, the air is cold. It is therefore heavy.
- Heavy air sinks, creating a high-pressure area. High pressure is related to clear and sunny skies.
- The air always moves towards low- pressure areas from high-pressure areas.
