Last lesson recap on
‘Contour lines’
• Answer the following
5 questions in your
exercise book.
• Write your answers
below your work on
contour lines from last
lesson.
1. What height is ‘Point A’ located at?
2. Which built up area is at the highest point above sea level?
3. What is the difference in height above sea level between Point B and the
highest point on Mt Erin?
4. What height is ‘Point B’ located at?
5. Which built up area is at the lowest point above sea level?
• Do you know what the lines on this world map are called?
• Do you know what these lines represent?
These lines are called lines of latitude and longitude
Latitude and longitude
Copy into your exercise book - Lines of latitude and longitude are used to locate places
accurately on the Earth's surface. These lines work like a giant grid reference map that
covers the entire globe.
Lines of latitude and longitude on a flat map projection of the world
Latitude
Copy into your exercise book - Lines of latitude circle the Earth in an east-west
direction. They are parallel to each other and are measured in degrees north or
south of the equator (0° latitude).
The equator also divides the globe into two hemispheres the northern hemisphere and the southern hemisphere.
Draw a simple circle with horizontal,
parallel lines in your book to help you
remember!
Latitude
Copy into your exercise book – Important lines of latitude include:
•
•
•
•
•
•
The Tropic of Cancer (23.5° north)
The Tropic of Capricorn (23.5° south)
The Arctic circle (66.5° north)
The Antarctic circle (66.5° south)
The North Pole (90° north)
The South Pole (90° south)
Longitude
Copy into your exercise book - Lines of longitude run from the top of the
Earth (North Pole) to the bottom (South Pole) in a north-south direction.

They are not parallel as lines of latitude are
They meet at a point at the north and south poles
They are called meridians.
They are measured in degrees.
• Important lines of longitude include:
• The Prime Meridian (0º longitude) which passes
through Greenwich in London, England.
• The International Date Line (180º east/west)
Draw a simple circle with vertical lines
that meet at the north/south poles in
your book to help you remember!
