4. When the time is 12 noon at 0° longitude, the time at 75 E longitude will be-

Answer: 5 p.m.

5. Which one of the following is a correct statement about longitudes?

Answer: All of them have equal lengths.

B.Fill in the blanks

1. The earth rotates from ___________ to ___________.

2. All the places on the same meridian will have the ___________ local time.

3. The distance between the two lines of latitudes is always ___________.

4. The ___________ are the imaginary lines that connect the north and south pales.

5. Each degree of longitude corresponds to a time difference of ___________ minutes.

1. Two division of earthHemispheres
2.Latitude are measured inDegree
3. Tropic of cancer23 Degree 30’N
4.British Royal ObservatoryGreenwich
5.The place through which standard meridian of india passesMirzapur

D. Answer the following questions in brief.

1. Which two basic points on the earth serve as the reference points?

Ans: (i) North Pole (ii) the South Pole

2. Mention the latitudinal location of the heat zones of the earth.

Ans: The latitudinal location of the heat zones of the earth are:

Torrid ZoneTropic of Cancer- Tropic of Capricorn 23 1/2oN to 23 1/2oSHottest
North Temperate ZoneTropic of Cancer- Arctic Circle 23 1.2oN to 66 1/2oNModerate
South Temperate ZoneTropic of Capricorn-Antarctic Circle 23 1/2oS to 66 1/2oSModerate
North Frigid ZoneArctic circle 66 1/2o to 90oN (North Pole)Coldest
South Frigid ZoneAntarctic Circle 66 1/2oS to 90oS(South Pole)Coldest

3. Why does the Torrid zone have the maximum temperature?

Ans: The torrid zone receives the maximum amount of heat throughout the year because the rays of the sun fall vertcally on this regon. This is located between the tropic of Cancer and Tropic of Capricorn in 23 1/2N to 23 1/2 S.

4. What is the significance of Greenwich Mean Time?

Ans: Greenwich Mean Time helps to know the international time and local time of a country.

5. Why is the Standard Meridian selected by a country a multiple of 7.5°?

Ans: The Standard Meridian selected by a country is a multiple of 7.5° because 15 degrees of longitude is equivalent to 1 hour in time (that is 360 / 24) it is convenient to adopt time zones at 7.5 degrees or 15 degrees multiples.In other words time zones are separated by multiples of 1 hour or 1/2 hour.

E. Answer the following questions.

1. State three main characteristics of parallels of latitudes.

Ans: Three main characteristics of parallels of latitude are:

  • Each degree of latitude is divided into 60 minutes and a minute is further sub-divided into 60 seconds.
  • These lines are parallel to each other and are of equal distance to each other and hence are called parallels of latitude.
  • Only the Equator is a Great Circle, all the rest of the latitudes are Small Circles.

2. Why do we use standard time? Explain with an example from India.

Answer: We know that places located on different meridians have different local times. It would create a lot of difficulties if a country adopts different local times.

For example, India lies between 68° 7’E and 97° 25’E longitudes. Thus, the people of India have to face problems of different local times. So, to avoid this problem and maintain its uniformity all over. a country, the standard time is used.

3. Which heat zone is most suitable for us to live and why?

Ans: Temperate zone is most suitable for us to live because the sun rays in this zone are never directly overhead. The angle of the sunrays decreases as we go towards the poles. That is why this zone is neither very hot nor very cold. They have moderate temperature.

4. Why is the time difference between each meridian of longitude 4 minutes? Explain.


The Earth rotates once a day, so that’s 360 degrees (the number of degrees in a circle) in 24 hours. If you do the math, that’s 360/24 = 15 degrees per hour. That is why, the time difference between each meridian of longitude is 4 minutes.

5. Distinguish between Equator and Prime Meridian.


EquatorPrime Meridian
Equator is the parallel of 0° latitude.Prime Meridian is 0º longitude runs through Greenwich England.
Equator divides the earth into Northern & Southern hemisphere.Prime Meridian divides the earth into Eastern & Western hemisphere.
