Longitudes and latitudes
What are longitudes?
These are imaginary lines that run from North Pole to South pole.
Longitudes are also called Meridians.
Which is the the main longitude?
Find the prime meridian from the picture.
The greenwich meridian which is 0°. There are 360 prime meridians. 180 of them are to the west of the greenwich meridian while the other 180 are to the east.
What are latitudes?
They are imaginary lines that run from West to East.
The main latitude is the equator [marked 0°]
Look for the equator in the picture below.
The equator divides the earth into Northern hemisphere and Southern hemisphere.
There are 180° latitudes in total. 90° of them are to the north of the equator and the other 90° to the south of the equator. Do you know of any other latitudes? The other longitudes include:
How do longitudes and latitudes help us?
They help us to give the position of a place when used together with the latitudes.
How do we locate position of a place in a map using longitudes and latitudes?
Here is a clue from the picture.
We start with the latitudes followed by the longitudes.
Can you tell the position of the circle?
It is between 10°N and 15°N and 15°E and 20°E.
Look at the map of East Africa.
Can you give the position of East Africa using longitudes and latitudes?
East Africa lies between 23°E and 52°E, 22°N and 12°S.
