#### 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.

#### For example

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.

#### Assigment

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.

• The earth is divided into the northern and southern hemispheres by the equator.
• There are 180° lines of longitudes on the west and east of the prime meridian.
