Which factor contributes to cooler temperatures in Mizoram’s higher altitudes?

The correct answer is: d) All of the above

Decreasing atmospheric pressure, distance from the equator, and increased cloud cover all contribute to cooler temperatures in Mizoram’s higher altitudes.

• Decreasing atmospheric pressure: As altitude increases, the atmospheric pressure decreases. This is because the air molecules are spread out further apart at higher altitudes. The lower atmospheric pressure means that there is less air to trap heat, which results in cooler temperatures.
• Distance from the equator: The Earth’s axis is tilted at an angle of 23.5 degrees. This means that the sun’s rays are more direct at the equator than they are at the poles. The more direct the sun’s rays, the warmer the temperature. Mizoram is located at a higher latitude than the equator, which means that it receives less direct sunlight and has cooler temperatures.
• Increased cloud cover: Clouds reflect sunlight back into space, which helps to cool the Earth’s surface. Mizoram has a higher average cloud cover than many other parts of the world, which contributes to its cooler temperatures.

In addition to these factors, the higher altitudes in Mizoram also experience lower humidity and less wind. These factors can also contribute to cooler temperatures.
