What height is ‘Point A’ located at?

1. 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. • What height is ‘Point A’ located at? • Which built up area is at the highest point above sea level? • What is the difference in height above sea level between Point B and the highest point on Mt Erin? • What height is ‘Point B’ located at? • Which built up area is at the lowest point above sea level?

2. Do you know what the lines on this world map are called? • Do you know what these lines represent?

3. These lines are called lines of latitude and longitude

4. 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.

5. Lines of latitude and longitude on a flat map projection of the world

6. 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!

7. 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)

8. Longitude • Copy into your exercise book - Lines of longituderun 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!

9. Prime Meridian 0º longitude International Date Line 180º longitude east/west

10. Latitude and longitude map of the world

11. Latitude and longitude • Task – • Colour the northern hemisphere in with one colour and the southern hemisphere in with another colour. • Draw and label the following latitude and longitude lines on your world map accurately. • 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) • Prime Meridian (0º longitude) • The International Date Line (180º east/west) Bonus – If you finish early, you can play the ‘Traveller IQ game.
