Direction: Read the following passages carefully and answer the question that follows.
Why doesn't the air remain still ? The reason is that air, when it becomes heated, becomes lighter, and it rises. When it rises, other air moves in to take its place. The temperature of air becomes like the surface of the earth over which it travels. Over dry land, the air can become very hot. Then, when the sun goes down, it cools off quickly. Over the water air heats up more slowly and cools off more slowly. These changes cause the movement of air,which we call wind.
Q.  Over dry land, the air?
  • a)
    heats up and cools off quickly
  • b)
    only heats up quickly
  • c)
    only cools off quickly
  • d)
    is still
Correct answer is option 'A'. Can you explain this answer?

Understanding Air Movement Over Dry Land
Air does not remain still due to the variations in temperature caused by differing surfaces, such as dry land and water. Over dry land, the behavior of air is influenced by rapid heating and cooling processes.
Heating of Air Over Dry Land
- Air tends to heat up quickly during the day when exposed to sunlight.
- The ground absorbs heat and transfers it to the air above, causing the air to become lighter and rise.
Cooling of Air After Sunset
- As the sun goes down, dry land loses heat rapidly.
- The air that has been heated during the day cools off quickly once the heat source (the sun) is no longer present.
Impact on Wind Formation
- When the warm air rises, it creates a vacuum that allows cooler air to move in and take its place.
- This continuous cycle of heating and cooling leads to air movement, which we perceive as wind.
Conclusion
Therefore, the correct answer is option 'A': Over dry land, the air heats up and cools off quickly. This dynamic interplay between temperature and air movement is crucial for understanding weather patterns and the formation of winds.
