Understanding Latitude and Longitude on a Map

To read and understand latitude and longitude on a map, it's important to know what these terms mean.

Latitude tells us how far north or south something is from the Equator.

• The Equator is at $0^\circ$.
• The poles are at $90^\circ$.

Longitude tells us how far east or west something is from the Prime Meridian.

• The Prime Meridian is also at $0^\circ$.
• It goes up to $180^\circ$.

Here’s how to find a point on a map using these coordinates:

1. Look at the Lines:

   • Latitude lines go across (horizontally), and longitude lines go up and down (vertically).
   • Together, they create a grid that helps us find exact locations.

2. Find Latitude First:

   • Check the latitude line.
   • If it says $45^\circ$ N, it means the place is halfway between the Equator and the North Pole.

3. Then Look for Longitude:

   • Next, find the longitude.
   • If the map shows $90^\circ$ W, the location is directly west of the Prime Meridian.

4. Put it Together:

   • A full coordinate will look like $45^\circ$ N and $90^\circ$ W.
   • This tells you exactly where a place is on Earth.

Knowing how to use these coordinates is very important!

They help guide us to specific spots around the world.

For example, using GPS technology helps people find their way every day.

This shows just how important it is to understand geography.

By learning how to read latitude and longitude, students can better understand our planet.

This knowledge is key for exploring and studying geography in the future!
