What effects do nearness to the sea and height above mean sea level have on the climate?

उत्तर
- Effects of nearness to the sea on the climate:
- Sea water gets evaporated due to the heat of the sun and thus water vapour gets mixed in the air.
- Thus, the air near the sea with higher temperature holds more amount of moisture.
- As a result, the climate near the sea is humid.
- As we move away from the sea, the moisture content in the air gradually decreases and the climate becomes dry.
- Effect of height above mean sea level on climate:
- Earth’s surface gets heated due to the heat of the sun.
- Thus, the air close to the surface of the earth becomes hot and the heat gets transferred vertically to the adjacent upper layers of the air.
- Thus, as we move upward from the sea level, the temperature of air decreases.
- Hence the temperature of the places at a higher altitude from sea-level is lower than the temperature of the places at a lower height.

This could be a classroom activity. If your school laboratory has an anemometer, use it to record your city’s wind speed for a week. Use the Beaufort Scale to find out the character of wind during these days. Record your observations carefully in your notebook. You could even draw small neat sketches to show the effect of the wind.
