Consider the following assertion and reason carefully:Assertion: The ...
Assertion and Reason Analysis:
The assertion states that the moving air is called the wind, which is a correct statement. The reason provided is that air moves from the region where the air pressure is high to the region where the pressure is low. This statement is also correct as wind is essentially the movement of air from areas of high pressure to areas of low pressure.
Explanation:
- Wind Formation: Wind is caused by the uneven heating of the Earth's surface, which creates differences in air pressure. Warm air rises, creating a low-pressure area, while cooler air sinks, creating a high-pressure area. This pressure difference causes air to move, resulting in wind.
- Direction of Wind: Wind always moves from areas of high pressure to areas of low pressure. This movement is due to the attempt to equalize the pressure imbalances in the atmosphere. The speed and direction of the wind are influenced by various factors such as temperature, topography, and the Earth's rotation.
- Impact of Pressure: The movement of air from high to low pressure areas is essential for balancing the Earth's atmospheric conditions. Wind plays a crucial role in distributing heat, moisture, and energy around the planet, affecting weather patterns and climate.
- Conclusion: Therefore, the assertion that moving air is called wind is accurate, and the reason provided regarding the movement of air from high to low pressure regions explains the formation and behavior of wind. Hence, both the assertion and reason are correct, but the reason is not a direct explanation of the assertion.

- Wind is the movement of air caused by the uneven heating of the Earth by the sun. It does not have much substance—you cannot see it or hold it—but you can feel its force.
- Warm equatorial air rises higher into the atmosphere and migrates toward the poles. This is a low-pressure system.
- At the same time, cooler, denser air moves over Earth’s surface toward the Equator to replace the heated air. This is a high-pressure system. Winds generally blow from high-pressure areas to low-pressure areas. The boundary between these two areas is called a front.
- The complex relationships between fronts cause different types of wind and weather patterns. Prevailing winds are winds that blow from a single direction over a specific area of the Earth.
