Question

Which one of the following statement is incorrect regarding the longitudes?
a. Longitudes are equal in length.
b. Longitudes are also known as meridians. c. Equator is the longest meridian running in the East-West direction.
d. Longitudes are semi-circles.​

Answer 1

Explanation:

a. Only the lines of longitude are of equal length. Each line of longitude equals half of the circumference of the Earth because each extends from the North Pole to the South Pole. The lines of latitude are not all equal in length.

b. Longitudes are known as meridians because in Geographical sense, meridians are great circles which are not parallel to each other but intersect each other at the North and the South Poles. ... All longitudes are great circles which meet at the Poles

c. Lines of latitude (parallels) run east-west around the globe and are used to measure distances NORTH and SOUTH of the equator. Since the equator is 0, the latitude of the north pole, 1/4 of the way around the globe going in a northerly direction, would be 90N

d. Each great circle is divided by the poles into two semi-circles called meridians of longitude. As the meridians run north and south, places having the same longitude will be due or due south of each other.

Answer 2

c) Equator is the longest meridian running in the East-West direction

Hence option C is the answer

It is incorrect
