Consider the following statements.1. The air pressure is highest at se...
Justification: Statement 1: Air pressure is defined as the pressure exerted
by the weight of air on the earth’s surface. As we go up the layers of
atmosphere, the pressure falls rapidly.
Statement 2: In areas where temperature is high the air gets heated and
rises. This creates a low-pressure area. Low pressure is associated with
cloudy skies and wet weather.
• In areas having lower temperature, the air is cold. It is therefore
heavy.
• Heavy air sinks and creates a high pressure area. High pressure is
associated with clear and sunny skies.
• The air always moves from high pressure areas to low pressure
areas.

Consider the following statements.1. The air pressure is highest at se...
Explanation:
Low air pressure is generally associated with cloudy skies and wet weather. This is because as air rises, it cools and condenses, forming clouds and precipitation. Therefore, areas of low pressure often experience cloudy and rainy conditions.
Reasoning:
- Statement 1: The air pressure is highest at sea level and decreases with height.
- This statement is correct. Air pressure is highest at sea level because the weight of the air above exerts the most pressure at this level. As you increase in altitude, there is less air above you, so the pressure decreases.
- Statement 2: Low air pressure is generally associated with cloudy skies and wet weather.
- This statement is also correct. Low pressure systems are often accompanied by rising air, which cools and condenses to form clouds and precipitation. This is why areas of low pressure are typically associated with cloudy and wet conditions.
Therefore, both statements are correct and provide accurate information about air pressure and its relationship to weather patterns.
