Answer (1):-

Parallels are another name for lines of latitude.

A line or surface that lies at or moves in the same direction as another but is always the same distance from it.

Four features of the parallels of latitudes are:

●Latitude is the angular distance of a place north or south of the Equator.

●There are 180 parallels of latitudes apart from the Equator.

●Each parallel of latitude is a circle.

●Only the Equator is a Great Circle, all the rest of the latitudes are Small Circles.

Answer(2) :-

We number the parallels on a globe starting with the equator,which is at 0 degrees. Lines of latitude to the north of equator are given 1 degree N to 90 degree N. Similarly to the south of equator.

Answer (3):-

Answer (3):- Meridian refers to a line of longitude on the Earth, making up one half of an imagined circle.

The meridians or lines of longitude have the following characteristics:

✅ All meridians are of the same length and each one is a semi-circle.

✅ If any two opposite meridians are taken together, they form a complete circle, which is a great circle.

✅The distance between any two meridians is maximum at the Equator, which is about 11 km for one degree of longitude.

✅ This distance decreases as we go away from the Equator towards the poles.

✅All the meridians meet at the poles.

Answer (4):-

Answer (4):-Latitude and longitude provide absolute location for a place on the globe. We can locate places on the globe by determining where lines on latitude and longitude cross. For instance, New Orleans, Louisiana is approximately 30N (latitude) and 90W (longitude).

Answer(5):-

Answer(5):-The length of the parallel increases as we move away from the poles towards the Equator because the Earth is spherical in shape and the circumference of the earth increases as we move towards the Equator.
