Solution
1.
Correct
All longitudes converge at the north and the south poles.
2.
Incorrect
Correct Statement
The consecutive longitudes are not parallel to each other. All the longitudes meet at the north pole and the south pole.
3.
Incorrect
Correct Statement
The 180° longitude is not the base longitude. The 0° longitude is the base longitude.
4.
Incorrect
Correct Statement
The Equator divides the Earth into the northern and southern hemispheres.

QUESTION
(C)
The figure below represents one hemisphere. Answer the following questions by observing the figure.
QUESTION
D)
Explain the difference between the latitudes and the longitudes with the help of a figure.
Solution
| Latitudes | Longitudes |
|---|---|
| (1) Imaginary circles drawn at a distance of one degree difference from each other, parallel in the east-west direction, are known as latitudes. | (1) The semicircular imaginary lines drawn from the center of the Earth at an equal angular distance from each other in the north-south direction are called longitudes. |
| (2) Latitudes are parallel to each other and never meet. | (2) Longitudes meet at the North Pole and the South Pole. |
QUESTION
E)

Solution
QUESTION
F)
Answer the following questions based on the observation of Figure no. 3.13.
Solution
1.
From which oceans and continents do all the longitudes pass?
Ans. All the longitudes pass through all the oceans—the Atlantic Ocean, Pacific Ocean, Indian Ocean, Arctic Ocean and Antarctic Ocean. They also pass through all the continents—Asia, Africa, Europe, North America, South America, Australia and Antarctica.
2.
From which oceans and continents does the Equator pass?
Ans. The Equator passes through the Pacific Ocean, Atlantic Ocean and Indian Ocean, and through South America and Africa.
3.
From which continents and oceans does the Prime Meridian pass?
Ans. The Prime Meridian passes through Europe, Africa and Antarctica, and through the Arctic Ocean, Atlantic Ocean, Southern Ocean and Antarctic Ocean.
4.
From which continents do both the 0° circles pass?
Ans. Both the Equator (0° latitude) and the Prime Meridian (0° longitude) pass through Africa.
5.
How many latitudes on the globe are circular in shape?
Ans. 179 latitudes are circular in shape. The remaining two are in point form.
