Globe Latitudes and Longitudes

Question 1: Answer the following questions briefly.

  1. What is the true shape of the Earth?
  2. What is a globe?
  3. What is the latitudinal value of the Tropic of Cancer?
  4. What are the three heat zones of the Earth?
  5. What are the parallels of latitude and meridians of longitudes?
  6. Why does the Torrid Zone receive the maximum amount of heat?
  7. Why is it 5.30 P.M. in India and 12.00 noon in London?

Answer:

  1. The Earth looks spherical in shape, but it is slightly flattened at the North and South Poles and bulges at the equator due to the outward force caused by the rotation of the Earth. This shape of the Earth is described as a ‘geoid’ meaning ‘an Earth-like shape’.
  2. Globe is a true model or miniature form of the Earth. It is used to study the earth as a whole. It shows continents, countries and oceans.
  3. The Tropic of Cancer lies 23.5 o North of the Equator.
  4. Following are the three heat zones of the Earth:
    1. the Torrid Zone,
    2. the Temperate Zone
    3. the Frigid Zone.
  5. All parallel circles from the Equator to the Poles are called parallels of latitudes. Latitudes are measured in degrees. The lines of references running from the North Pole to the South Pole are called meridians of longitudes. Longitudes are also measured in degrees.
    1. The area between the Tropic of Cancer and the Tropic of Capricorn is known as the Torrid Zone.
    2. The mid-day Sun is exactly overhead at least once a year on all these latitudes. Hence, this area receives the maximum amount of heat.
  7. In London, the Greenwich Mean Time (GMT) is followed. The Indian Standard Meridian is located 82 .5o East of the Prime Meridian(I.e. 0 degrees). Thus the Indian Standard Time(IST) is 5 hours and 30 minutes ahead of GMT. So, when it is 12 noon in London, it is 5.30 in India.

2: Tick the correct answers.

  1. The value of the Prime Meridian is
    1. 90o
    2. 0o
    3. 60o
  2. The frigid Zone lies near
    1. the Poles
    2. The equator
    3. The tropic of Cancer
  3. The total number of longitudes are
    1. 360
    2. 180
    3. 90
  4. The Antarctic Circle is located in
    1. The Northern Hemisphere
    2. the Southern Hemisphere
    3. The Eastern Hemisphere
  5. The grid is a network of
    1. Parallels of latitudes and meridians of longitudes
    2. The tropic of cancer and the tropic of Capricorn
    3. The North Pole and the South Pole.

Answer:

  1. (ii) 0 o
  2. (i) The Poles
  3. (i) 360
  4. (ii) The Southern Hemisphere
  5. (i) Parallels of latitudes and meridians of longitudes

Answer:

  1. The Tropic of Capricorn is located at 23 .5 o south of the Equator.
  2. The Standard Meridian of India is 82 .5o E.
  3. The 0 o Meridian is also known as the Prime Meridian.
  4. The distance between the longitudes decreases towards the Poles.
  5. The Arctic Circle is located in the Northern Hemisphere.
