The graticule

This is a very accurate way of pinpointing an exact location of a place. 

But how does it work? 

Paralells

We have the equator at 0 degrees latitude. The equator divides the earth in the Northern and Southern hemisphere. 

Paralells

At the North and South pole we've reached the maximum amount of degrees, that is 90. 

Keep in mind that the degrees aren't the temperature, but the distance from the equator.

Meridians

Meridians of longitude run from the North pole to the South pole and run in a 360 degree circle. 
These meridians of longitude tell us wether we are on the western part of the world or the eastern part. 

Prime meridian

This prime meridian runs through Greenwich and splits the Earth in the Western and Eastern hemispheres. 

The longitude lines go from 1 degrees west longitude until 180 degrees (half of the earth)

The graticule

While using the latitude and longitude lines we can pinpoint the precise location of a certain place on the Earth. 

Weather & Climate

Go to page 237 in the Atlas
Find the city Quito in Ecuador (South-America)

1. It's on a parallel
2. It's on a meridian

Find now the city of Adelaide
(in the south of Australia)

1. This city is close to the 140° parallel
2. This city is close to the 140° meridian.

Locating a city - coordinates

Write in your notebook:

Step 1: find the city in the atlas.

Step 2: is the city in the Northern (N.) or Southern (S.) hemisphere?

Step 3: find out on which distance (in degrees / °) from the Equator
                (left/right of the map) - For example 45° N.

Step 4: decide if the city is in the Western (W.) or Eastern (E.) hemisphere,                         

                that means: is the city to the West from London or to the East.

Step 5: find out how far from the prime meridian (top/bottom of the map)                   

                For example 140° E.

Now find the city of
Kaapstad (South-Afrika).
What is the correct notation?

1. 35° N., 18° W.
2. 35° W., 18° N.
3. 35° S., 18° E.
4. 35° E., 18° S.
