Q1: Why do we have Standard Time?
Ans:
Q2: What is the Meridian that is taken as the standard time of India?
Ans: In India, 82° 30' E is regarded as a standard meridian because the time difference between 1° longitude and 82° 30' E is 4 minutes.
The whole longitudinal space of India is 30 degrees (97°E - 67°E = 30°E). As a result of the total time difference of 30 X 4 = 120 minutes or 2 hours, the time difference between Gujarat and Arunachal Pradesh is 2 hours.
We chose a standard meridian to avoid such confusion and to ensure that everyone in the country is on the same time.
Q3: Why is having a standard time is necessary? Define IST.
Ans: Indian Standard Time is abbreviated as IST. Every country must have a standard time zone. The following things will help to understand it:-
Q4: Kabeer lives in a small town near Bhopal. He tells his friend Alok that they will not be able to sleep tonight. A day and night cricket match between India and England had started, at 2 p.m. in London. This means that the match would finish well after 1 a.m. in the night. The match according to Indian Standard Time (1ST) has started at 7.30 p.m.
Do you know what is the time difference between India and England?
Ans:
Q5: What are the meridians of longitude and parallels of latitude?
Ans: The imaginary line that separates the planet into the Northern and Southern Hemispheres is known as the Equator. By 0 degrees latitude, the equator is represented. The North Pole is located at 90° north latitude, whereas the South Pole is located at 90° south latitude. The world is divided into equal halves by this circular line. From the equator to the poles, there are parallel circles. The measurement units for latitudes are degrees.
Q6: Torrid zones receive maximum amount of heat, why?
Ans: The Torrid Zone is located between the Tropics of Cancer and Capricorn. On all of the latitudes included in this area, the midday sun is directly overhead once a year. This occurs as a result of the fact that this area receives the most heat. Because the sun's rays fall vertically on this region, the torrid zone receives the most heat throughout the year. It is between the Tropics of Cancer and Capricorn, between 23 1/2N and 23 1/2S.
Q7: How do longitudes help us in calculating time?
Ans: Longitude and Time:
It takes 24 hours for the earth to complete one rotation:
Q8: What is Standard Time?
Ans: Standard Time:
Q9: Explain about the three heat zones of the earth.
Ans: The earth's three heat zones are:

Q11: Describe major heat zones of the Earth.
Ans: Heat Zones of the Earth.
1. Torrid Zone:
2. Temperate Zone:
3. Frigid Zone:
