Longitudes

3. The three dimensional model of the Earth.

globe

4. India is located in this hemisphere based on lines of longitude.

5. The network of lines of latitude and longitude.

VIII. Answer Briefly :

1. What is a geoid?

  • The Earth cannot be compared with any other geometrical shape as it has a very unique shape.
  • Hence, its shape is called a geoid (earth shaped).

2. What is local time?

  • The time in a particular region or area expressed, with reference to the meridian passing through it. (or)
  • When the sun is overhead on a particular line of longitude, it is 12 noon at all the
    places located on that line of longitude. This is called local time.

3. How many times would the sun pass overhead a line of longitude?

The sun is overhead on a line of longitude only once a day.

4. What are lines of latitude and longitude?

  • The imaginary lines that run east and west direction on the Earth are called lines or parallels of latitude
  • The imaginary lines drawn vertically connecting the North pole and the south pole are called lines or meridians of longitude.

5. Name the four hemispheres of the Earth.

  1. Northern Hemisphere,
  2. Southern Hemisphere,
  3. Eastern Hemisphere and
  4. Western Hemisphere.

IX. Give Reasons :

1. The 0° line of longitude is called the Greenwich Meridian.

  • All nations of the world agreed to have the Greenwich Meridian as the international Standard Meridian (0°).
  • This line of longitude is called the Prime Meridian and it is also known as the Greenwich Meridian because it passes through Greenwich.

2. The regions on Earth between North & South lines of latitude (66 V20) and poles (90°) is called Frigid Zone

This region receives very slanting rays of the sun. The temperature is very low. Hence, this
region is known as Frigid Zone.

3. The International Date Line runs zigzag.

  • The International Date line is not straight.
  • If the line is drawn straight, two places in the same country world have different dates.
  • So the International Date line is found zigzag in certain places to avoid confusion.

X. Answer in detail :

1. What are the uses of globe?

  • Since the Earth is huge and we live on a very area, we are not able to see the Earth as a whole.
  • But when we travel to space, we can see the Earth as a whole.
  • So, in order to see the shape of the Earth as a whole and to know its unique features, a three dimensional model of the Earth was created with a specific scale in the name of globe.

2. Explain; Indian Standard Time.

  • The longitudinal extend of India is from 68° 7’E to 97° 25’E
  • As many as twenty nine lines of longitude pass through India.
  • Having 29 standard time is not logical.
  • Hence 821/2° E line of longitude is observed as the prime meridian to calculate the Indian standard Time.
