Facts About Weather
Question 1:
Why Does the Weather Change Many Times During the Day?
Answer:
- Weather changes daily due to wind currents, humidity, temperature and water cycle.
- Whereas seasonal changes occur because of the revolution of Earth around the Sun.
Question 2:
The Thermometer That We Use for Measuring the Air Temperature Contains Mercury. Why Not Any Other Substance Used Instead of Mercury?
Answer:
- The thermometer is a device used to measure the degree of hotness or coldness of an object, body or place.
- A clinical thermometer is used for measuring the body's temperature, whereas a laboratory thermometer is used to measure the temperature of the surroundings.

- It can contract or expand with the slightest change in the temperature; hence used mostly.
Question 3:
Why Is the Weather in the Mountain Area Colder Than in the Area Near the Sea?
Answer:
- As we move to the heights, the air density decreases, leading to a fall in the concentration of gases in the air.
- A decrease in the amount of carbon dioxide leads to a fall in temperature as it plays a prominent role in absorbing the Sun’s heat and maintaining an optimum temperature.
Question 4:
What Causes Thunder in Rainy Clouds?
Answer:
- We see huge lightning due to the collision of big rainy clouds with each other.
- When this light travels towards Earth, it passes through the clouds, creating a path amidst the atmosphere or air.
