Question

Which latitude is the longest?
a. 23 degrees North
b. 66 degrees North
c. 0-degree
d. 80 degrees North

Answer 1

Hint:
The Length of Longitudes is similar all around the globe.
The Distance between latitudes gets shorter at poles.
The Latitudes are the horizontal lines circling the spheroid earth, hence tend to be short towards either side of the sphere.

Complete step by step solution:
Latitude:
Latitude is the distance measurement to the north or south of the Equator. It is determined by 180 imaginary lines forming circles east-west around the Earth, parallel to the Equator. Such lines are referred to as parallels. An imaginary ring connecting all points sharing a parallel is a circle of latitude.
Equator:
The Equator is a line around the centre of a planet or other celestial body that is imaginary. At a latitude of 0 degrees, it is halfway between the North Pole and the South Pole. The world is divided into the Northern Hemisphere and the Southern Hemisphere by the equator.
Longest latitude:
Latitude lines (parallels) run east-west across the globe and are used for calculating the equator's NORTH and SOUTH distances. Since the equator is 0 degrees, 90 degrees N will be the latitude of the north pole, 1/4 of the way around the globe going in a northerly direction. It's the longest possible latitude.
The equator is centred at a latitude of 0 degrees, meaning it is centred at the earth's circumference. As u know the sphere is the shape of the earth, that's why the equator is the longest latitude line.
Hence, the correct answer is option C.

Note:
There are not so many special lines and points in latitude compared to longitude, just note all latitude lines are of the same length. The only latitudes that are unique are 0 degrees and 180 degrees.
The largest circle on the globe is the equator at 0 degrees, i.e. as an equatorial area, the region surrounding it is known to obtain similar amounts of sun rays during the year. It is the hottest of the Earth's other two regions.
