1 Latitude and Longitude
Mini Lesson - Grade 8

2 Essential Question: How is absolute location found? Objective: SWBAT: Locate places on earth, using latitude and longitude.

3 Why use latitude and longitude?
lines on a globe form a grid system help locate places on the earth easily Latitude - or parallels circle the earth parallel to the equator Longitude - or meridians circle the earth from pole to pole

4 Latitude Latitude lines measure distance north and south of the equator. The equator is 0 degrees. At what degrees is the North Pole? South Pole? How did you determine this?

5 Longitude Lines of longitude measure distance east and west of the Prime Meridian. The Prime Meridian is 0 degrees longitude. The Prime Meridian runs through Greenwich, England.

6 Absolute Location Together the lines form a grid system which enables us to find the absolute location of a place on earth

7 Absolute Location Only one place on earth can be found at the specific point where a specific line of latitude crosses a specific point of longitude. By using degrees and minutes, people can locate a precise spot on earth. Mystery - How do we differentiate between the Equator and Prime Meridian is they are both at 0 degrees????

8 Latitude is always first!
When giving a coordinate or trying to find a place on earth, latitude must always be given first. So….. If trying to find 0, 30W, you know 0 degrees is referring to the equator, why?

9 Finding locations Since latitude measures distance north or south of equator, it must always have a N or S after it. For example: 10 N, 60 E Longitude measures distance east and west of the Prime Meridian so it must alway be given second and have a E or W after it.

10 Where in the world is it? Continent at 40 N, 100 E? Ocean at
20 S, 80 E 80 S, 0 Give the coordinates of Africa and Europe

11 What did you learn? Why are latitude and longitude important?
What does latitude measure? Longitude? If you are giving the coordinates 45 N, 0 , how do you know what line zero refers to? Explain… Any questions?
