# NCERT Solution Class 6 Social Science Geography Chapter 2: Latitudes and Longitudes

## Answer the following questions briefly.

### a. What is the true shape of the earth?

Answer: The true shape of the Earth is not sphere. It is a bit flattened at the two poles, North and South and bulge in the middle.

### b. What is a globe?

Answer: A globe is a small/miniature form of the Earth.

### c. What is the latitudinal value of the Tropic of Cancer?

Answer: Tropic of Cancer is present in the Northern Hemisphere. The latitudinal value of the Tropic of Cancer is 23½° N.

### d. What are the three heat zones of the Earth?

Answer: The three heat zones of the Earth are:

1. Torrid Zone
2. Temperate Zone
3. Frigid Zone

### e. What are parallels of latitude and meridians of longitude?

Parallel of latitudes: The parallel circles starting from the equator up to the poles are called parallels of latitudes.

Meridians of longitudes: The line of references running from the North Pole to the South Pole are called meridians of longitudes.

### f. Why does the torrid zone receive maximum amount of heat?

Answer: The area between the Tropic of Cancer and Tropic of Capricon is the torrid zone. The mid-day sun is exactly overhead on the latitudes lying in the Torrid zone. Thus, it receives maximum amount of heat.

### g. Why is it 5.30 p.m. in India and 12.00 noon in London?

Answer: India is located at east of Greenwich at 82°30'E, which is 5 hours and 30 minutes ahead of GMT (Greenwich Mean Time). Thus, when it is 12:0 noon in London, it is 5:30 in India.

## 2. Tick the correct answers.

a. The value of the prime meridian is

1. 90°
2. 60°

Explanation: The count begins from the Prime Meridian.

b. The frigid zone lies near

1. the Poles
2. the Equator
3. the Tropic of Cancer

Explanation: The poles receives less sun rays.

c. The total number of longitudes are

1. 360
2. 180
3. 90

Explanation: The count begins from Prime Meridian. 180 is counted eastward and 180 is counted westward. Thus total is 180 + 180 = 360.

d. The Antarctic cirlce is located in

1. the Northern hemisphere
2. the Southern hemisphere
3. the Eastern hemisphere

Explanation: Antarctic circle is located in the Southern hemisphere.

e. Grid is a network of

1. parallels of latitudes and meridians of longitudes
2. the Tropic of Cancer and the Tropic of Capricon
3. the North Pole and the South Pole

Answer: i. parallels of latitudes and meridians of longitudes

Explanation: Grid helps us to easily locate any point on the Globe.

## 3. Fill in the blanks.

1. The Tropic of Capricon is located at the 23½° S.
2. The Standard Meridian of India is 82½° E (82° 30'E).
3. The 0° Meridian is 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.
