Determining Location

Mapping Pre-Assessment 1. Which is a measure of how far East or West you are traveling? Latitude B. Longitude C. Attitude D. Altitude 2. At 180° longitude, this imaginary line separates one day from another. Prime Meridian B. International Date Line C. Arctic Circle D. Equator

A. 38° N B. 75° W C. 38° W D. 75° N

What are the coordinates for San Francisco? What city is found at approximately 39°N, 106°W?

A+ Why are we Learning about Latitude and Longitude? How could you describe the exact location of a dot on a basketball? It would be just as hard to describe a position on earth without some sort of grid system to give you an exact location. This grid system is called latitude and longitude.

Latitude and Longitude Latitude – imaginary lines which run east and west BUT measure degrees north or south of the equator 0° latitude is the Equator These lines never cross

Latitude and Longitude Longitude – imaginary lines that run from North to South Pole but measure degrees east or west of the Prime Meridian 0° longitude is the Prime Meridian These lines cross at the north and south pole

International Date Line - 180° longitude line It separates two consecutive calendar days Note: left of line is one day ahead of right side

Northern Hemisphere Western Hemisphere Eastern Hemisphere Southern Hemisphere

The coordinates for Miami, FL (see arrow) would be: How to Use It: When saying or writing your location on a map you always: 1. Latitude (number, degrees, N or S) 2. Longitude (number, degrees, E or W) The coordinates for Miami, FL (see arrow) would be: 25°N, 80°W

Example Charlotte, NC is located at 35° N, 80° W

What would be the latitude and longitude for the arrow pointing at the border between California and Nevada?

It should be: 40°N, 120°W

Write the approximate latitude and longitude for: OK, now lets do a couple more practice problems. Open your book to pg. 745 and write the answers in your notes: Location at 40°N, 105 °W Location at 47 °N, 87 °W Write the approximate latitude and longitude for: New York, NY Hawaii (Big Island)

0° Longitude is the Prime Meridian O° Latitude is the Equator

Latitude & Climate As you increase in Latitude the temperature decreases

Other Important Lines of Latitude What is important about these imaginary lines?
