Key Terms Create a flash card for the following key terms (p. 53 in textbook): • Parallel • Latitude • Meridian • longitude If you finish early, study your flash cards!
Latitude • Circles or lines north and south of the equator are called lines of latitude or PARALLELS. • Latitude is the angular distance north or south of the equator.
Measuring Latitude • Latitude is measured in degrees, it is the angular distance North or South of the Equator • Equator is starting point: 0 Degrees • Each line of latitude increases by 15 degrees. • North of the equator = N • South of the equator = S
Measuring Latitude • Each degree of latitude consists of 60 equal parts called MINUTES (‘) • Each Minute is divided into 60 SECONDS (“). • Precise Latitude for Washington D.C. = 38˚53’23” North
Quick Check! • Circles of Latitude are _______ and _______ of the equator. • Latitude is measure in ________, ______, and ________. • Each line of latitude is _____ degrees north or south of the previous line.
Longitude • Longitude shows a location East or West of the PRIME MERIDIAN, 0 degrees. • It is angular distance east or west of the Prime Meridian. • Lines of Longitude are in 15 degree increments and are composed of minutes and seconds.
Longitude • At the equator the distance between each line of longitude is 111 km. • All meridians meet at the poles, so the distance between each line of longitude (meridian) decreases as you move toward the poles.
Quick Check!! • Lines of longitude are also called ____________. • The ________ __________ is zero degrees longitude. • Distance between meridians _______ as you travel to the poles.
Great Circles • A GREAT CIRCLE is any circle that divides the globe in half. • A GREAT CIRCLE can run in any direction. • A GREAT CIRCLE is the shortest distance between 2 points on a sphere.
