LONGITUDE AND LATITUDE
Hemispheres • Remember, hemispheres divided the earth into 4 halves. • These halves will help you in being successful at Longitude and Latitude!
Latitude and Longitude • These are two sets of lines used for pinpointing locations everywhere on Earth • Where these two lines cross is your exact location. • These lines are assigned a number or degrees to tell us how far away they are from the equator or prime meridian.
What is Latitude? • They measure how far something is from the equator. • also called parallels because they stay the same distance apart all around the world. • The equator is very important because it is the starting point for measuring latitude distance. It is the 0° latitude line. • The lines farthest from the equator are 90 °. This is the north pole and the south pole. Latitude lines above the equator are North. 90° N 0° 90° S Latitude lines below the equator are South.
latitude • Latitude lines are parallel like steps on a ladder. • They stack on the earth, like this baby toy. • Each line has its own number.
What is longitude? • They measure how far something is from the prime meridian. • Also called meridians, they are NOT parallel because these lines meet together at the poles. • The prime meridian is very important because it is the starting point for measuring distance. It is the 0° longitude line. • The line farthest from the prime meridian is 180 °. It is actually the rest of the prime meridian circle…It is named the International Date Line. These lines all meet here at the North pole… 0° Prime Meridian …and at the South pole.
longitude • Looks like a peeled orange. • What degrees is the Prime Meridian on the other side of the Earth? The lines to right are in the Western Hemisphere and are labeled West. A half of a circle is 180°. That is why the other half of the prime meridian is 180°. The lines to right are in the Eastern Hemisphere and are labeled East.
longitude • The 0° prime meridian and 180° international line are a part of the same circle. They are just on opposite sides of the Earth. PRIME MERIDIAN INTERNATIONAL DATE LINE
How to use Latitude and Longitude • Coordinates are a pair of numbers – It is really a latitude number and a longitude number PRIME – (60° N, N 90° W) W MERIDIAN • Latitude is always first. Longitude is always second. EQUATO R
How to use Latitude and Longitude • Where these two lines cross, is the exact location of the coordinates. (60° N, N 90° W) W
