1 Guided Notes on Latitude and Longitude

2 Define Cartography: ► Cartography is the science of mapmaking

3 What is the equator? Where is it located? ► The equator separates the Earth into 2 hemispheres. It circles the Earth halfway between the North and South Poles

4 Define and describe Latitude and Lines of Latitude ► Latitude is the distance in degrees north or south of the equator ► Lines running parallel to the equator are lines of latitude

5 ► Each degree of latitude is equal to 111km. To locate positions on Earth more precisely, cartographers break down degrees of latitude into sixty smaller units called minutes.

6 ► One minute of latitude is equal to 1.85 km. Minutes of latitude can be divided into 60 seconds.

7 Define and describe Longitude and Lines of Longitude ► Longitude is the distance in degrees east or west of the prime meridian. ► Lines of longitude locate positions in east or west directions.

8 What is the Prime Meridian? Where is it located? ► The prime meridian is a line of longitude that represents 0° longitude. It runs from the north pole to the south pole through Greenwich, England.

9 ► Unlike lines of latitude, lines of longitude are not parallel. Instead, they are large semicircles that extend vertically from pole to pole.

10 ► 180° longitude is also known as the International Date Line.

11 ► The distances covered by degrees of longitude vary with location. One degree of longitude varies from about 111km. at the equator to a point at the poles.

12 ► In reference to the coordinates of a particular location, latitude always comes first.

13 Why is the earth divided into 24 time zones? ► Each time zone represents one hour in the 24 hours it takes for the earth to rotate on its axis.

14 ► Each time zone is 15° wide, but some boundaries are adjusted because they would run through cities in which it would be confusing to have 2 different times.
