Latitude:
* Think of it as horizontal lines. Latitude lines run parallel to the equator, which is at 0 degrees latitude.
* Measures distance north or south of the equator. Angles increase from 0° at the equator to 90° at the North Pole and 90° at the South Pole.
* Determines a location's position relative to the equator. For example, 40° North means a location is 40 degrees north of the equator.
Longitude:
* Think of it as vertical lines. Longitude lines run from the North Pole to the South Pole, passing through the Prime Meridian (0 degrees longitude).
* Measures distance east or west of the Prime Meridian. Angles increase from 0° at the Prime Meridian to 180° east and 180° west.
* Determines a location's position relative to the Prime Meridian. For example, 75° West means a location is 75 degrees west of the Prime Meridian.
Putting it together:
* Coordinates: A specific location is identified by its latitude and longitude coordinates. These are expressed as two numbers, separated by a comma, like this: 40.7128° N, 74.0060° W.
* Finding a location: When you have the coordinates of a place, you can find it on a map or a globe.
Example:
Imagine you are trying to find the Eiffel Tower. You know its coordinates are 48.8584° N, 2.2945° E. This means:
* The Eiffel Tower is 48.8584 degrees north of the equator.
* It is 2.2945 degrees east of the Prime Meridian.
Importance:
* Navigation: Latitude and longitude are essential for navigation, both for ships at sea and airplanes in the air.
* Mapping: They are used to create maps and to pinpoint locations on the Earth.
* GPS: Global Positioning Systems (GPS) rely on latitude and longitude to determine your location.
