Latitude and Longitude Patterns

Name: _________________________________________________ Block: _______ Date: _______________HOW LONGITUDE AND LATITUDE HELP US SEE PATTERNS ON EARTHDirections: Go to the following website:http://www.classzone.com/books/earth_science/terc/navigation/home.cfm. Type in the following code: ES0303and select Go! Complete the questions listed below. You MUST read all of the information on each screen tocorrectly complete the assignment.1. How does sea surface temperature appear to change with latitude?2. How does sea surface temperature appear to change with longitude?3. Which lines (longitude or latitude) run from north to south?4. Which lines (longitude or latitude) run from east to west?5. Which line is the reference line for longitudes? Draw this reference line on the above map.6. Which line is the reference line for latitudes? Draw this reference line on the above map.

7. Use colored pencils to trace these patterns onto your printed map. Describe the distribution of seasurface temperatures around the world.8. How does sea surface temperature change along latitude lines?9. How does sea surface temperature change along longitude lines?10. What conclusion might you have drawn had you looked at global sea surface temperature along only onelatitude line?11. How does the time of the year affect the distribution of global sea surface temperature?The technology for determining location is called the _______________ __________________________________(GPS). The GPS consists of _________satellites orbiting Earth. A GPS receiver gathers andanalyzes signals from the satellites to determine and report its location. Using a hand-held receiver or one that isbuilt into a ship, airplane, truck, or car, it is possible to find the latitude and longitude of almost any place onEarth to within a few meters.Make sure you view the video of how GPS works.
