D. Answer these questions.
1. Why are latitudes also called parallels of latitudes?
= The lines of latitude are circles running parallel to each other and lie between the Equator and the two poles. As they run parallel to each other, these lines are called parallels of latitudes.
2. Which is the longest latitude and what is it also known as?
= The Equator is the longest latitude. It is also known as the Great Circle.
3. How do latitudes and longitudes help us locate the places on Earth?
= The latitudes and longitudes intersect each other to form a network of lines over the globe which is known as grid. This grid helps us to locate places on the Earth. So, if we know the latitude and longitude of a particular place, then the point where these two lines intersect each other is the exact location of that place on Earth.
4. Write a short note on the Prime Meridian.
= The Prime Meridian is the 0° longitude that passes through the Royal Observatory at Greenwich, near London. It is considered to be the starting point of longitudes. The time of any place is calculated with reference to the Prime Meridian. The time at the Prime Meridian is known as Greenwich Mean Time (GMT).
5. Distinguish between lines of latitude and meridians of longitude.

Lines of Latitude |
Meridians of Longitude |
|---|---|
|
1.They extend east-west direction. |
1.They extend north-south direction. |
|
2. They are full circles. |
2. They are semi-circles. |
|
3. They decrease towards the poles. |
3. They are of same radius. |
|
4. They are parallel to each other. |
4. They are not parallel to each other. |
|
5. Apart from the Equator, there are 180 parallels of latitude. |
5. There are 360 longitudes. |
Picture Study
Look at the picture and answer the questions.
1. What is depicted in the picture?
= The latitudes and the longitudes are depicted in the picture.
2. How does it help us?
= They help us to location a place on Earth. The longitudes help us to calculate the time of a particular place.
