Question

Can you find the exact location of a place on the globe by using only the latitude? What about the north and south poles?

Answer 1

Nope ! 
You cant find exact location with only latitude 
You always need one longitude to intersect 
North and south poles are opposite to each other 

Answer 2

Hey there !!

You cannot find the exact position using only a latitude as you also need a longitude to find the exact position.

So, you need both latitude and longitude to locate the exact position.
