Latitude:
* Imagine Earth sliced horizontally like an orange. Latitude lines run east to west, parallel to the equator.
* The equator is 0 degrees latitude. Latitude values increase as you move north or south of the equator, up to 90 degrees at the North and South poles.
* Latitude tells you how far north or south a location is from the equator.
Longitude:
* Now imagine those slices of orange being further divided vertically. Longitude lines run from north to south, passing through both poles.
* The prime meridian is 0 degrees longitude. It runs through Greenwich, England. Longitude values increase as you move east or west of the prime meridian, up to 180 degrees.
* Longitude tells you how far east or west a location is from the prime meridian.
Together, latitude and longitude create a unique coordinate for every point on Earth:
* For example: The coordinates 40° N, 74° W represent a location in New York City.
* 40° N means it's 40 degrees north of the equator.
* 74° W means it's 74 degrees west of the prime meridian.
In summary, latitude and longitude allow us to:
* Identify the precise location of any point on Earth.
* Navigate and travel across the globe.
* Understand the geographic relationships between different places.
* Create maps and other geographic representations.
