VIII. Answer briefly

Question 1.
What is a geoid?
Answer:

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

Question 2.
What is the local time?
Answer:

1. When the sun is overhead on a particular line of longitude, it is 12 moon at all the places located on that line of longitude.
2. This is called local time.

Question 3.
How many times would the sun pass overhead a line of longitude?
Answer:
The sun is overhead on a line of longitude only once a day.

Question 4.
What are lines of latitude and longitude?
Answer:

1. There are imaginary lines which are drawn on the globe horizontally and vertically to find a location and calculate distance and time.
2. These imaginary lines are called lines of latitudes and longitudes.

Question 5.
Name the four hemispheres of the Earth.
Answer:

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

IX. Give reason

Question 1.
The 0° line or longitude is called the Greenwich Meridian.
Answer:
The 0° line of longitude is called the Greenwich Meridian because it passes through Greenwich.

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

1. From the Arctic circle (66 ‘A° N) to the North Pole (90° N) and from the Antarctic circle (66 Vi0 S) to the South Pole (90° S) the sun’s rays full further inclined, through out the year.
2. The temperature is very low.
3. Hence this region is known as Frigid Zone.

Question 3.
The International Date Line runs zigzag.
Answer:
If the International Date line is drawn straight, two places in the same country would have different dates. So the International date line is found Zig Zag to avoid confusion.

X. Answer in detail

Question 1.
What are the uses of globe?
Answer:

1. Since the Earth is huge and we live on a very area, we are not able to see the Earth as a whole.
2. But when we travel to space, we can see the Earth as a whole.
3. 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 the globe.

Question 2.
How are the hemispheres divided on the basis of lines of latitude and longitude? Explain with diagrams.
Answer:
Northern Hemisphere:
Northern Hemisphere. The area of the Earth found between the Equator (Oo) and the North pole (90oN) is called the Northern Hemisphere.

Southern Hemisphere:
Southern Hemisphere. The area of the Earth from the Equator (0°) and the South pole (90°S) is called the Southern Hemisphere.

Eastern Hemisphere:
Eastern Hemisphere. The part of the Earth between the 0° line of longitude and 180° East line of longitude is known as the Eastern Hemisphere.

Western Hemisphere
Western Hemisphere. The part of the Earth from Oo line of longitude and 180° West line of longitude is called as Western Hemisphere.

Question 3.
What are the significant lines of latitude? Explain the zones found between them.
Answer:

1. The significant lines of latitude are
2. Equator 0°
3. Tropic of cancer 23 1/2° N
4. Tropic of Capricorn 23 1/2° S
5. Arctic Circle 66 1/22°N
6. Antarctic Circle 66 1/2° S
7. North Pole 90° N
8. South Pole 90° S
9. Based on the amount of heat received from the sun, our world is broadly divided into three heat zones.

1. The Torrid Zone : On both sides of the equator, the region lying between the Tropic of cancer and Tropic of Capricorn is called the Torrid zone. This zone gets the direct rays of the sun all the year round. Hence the climate is hot and humid.

2. The Temperature Zone : This zone is neither hot nor very cold. It lies between the Torrid zone and Frigid zone in both the hemispheres.

3. The Frigid Zone : The region lying between the Arctic circle and North pole and between Antarctic circle and south pole is called the frigid zone. It receives very slanting rays of the sun and is therefore very cold.

Question 4.
Explain : Indian Stanard Time.
Answer:

1. The longitudinal extent of India is from 68° 7’E to 97° 25’E
2. Twenty nine lines of longitude pass through India.
3. Having 29 standard time is not logical
4. Hence 821/2° E line of longitude is observed as the prime meridian to calculate the Indian standard Time (IST)

XI. Activity

There are five Posistion marked on the grid given below. Look at them carefully and fill the blanks with reference to the lines of latitude and longitude. The first one is done for you.

1. The latitudinal and longitudinal reference of point A 40° N 30°W
