Question

Weather is predicted by considering
A. The movement of air
B. Amount of water vapour
C. Temperature
D. All the above

Answer 1

Hint: Weather is the day-to-day atmospheric conditions of a particular region. It takes into consideration the temperature, humidity and precipitation levels in that particular region.

Complete Answer:
Let us look at each option one by one.
- The movement of air is called wind. The strength of the wind blowing in a region affects the temperature as well as precipitation index of that region. Therefore, movement of air is essential for the prediction of weather.
- Amount of water vapour present in the atmosphere determines the humidity in a region. Humidity is an important factor of day-to-day weather forecast. Therefore, the amount of water vapour is essential for the prediction of weather.
- Temperature is the most important aspect of weather prediction. The temperature of a region determines if the day will be hot or cold or moderate. Therefore, temperature is essential for the prediction of weather.
- Since the factors mentioned in the aforementioned points are essential to the prediction of weather, all the above is the correct option.

Thus, the correct answer to this question is (D) All the above.

Note: The weather of a particular place at particular time can be classified into four major types:
1. Sunny- Here, the sun shines brightly in the sky with no clouds hindering its rays.
2. Windy- Here, the movement of air is faster than its normal velocity.
3. Cloudy- Here, there is an excess of clouds in the sky such that the sun rays are blocked.
4. Rainy- Here, the water storage capacity of the clouds reaches its maximum and thus, falls on the earth in the form of rain.
