* Meridians run north-south: Meridians are lines of longitude that circle the Earth from pole to pole. They are used to define east-west positions.
* You need both latitude and longitude: To pinpoint a location on Earth, you need both longitude (meridian) and latitude (a line of latitude that circles the Earth parallel to the equator).
Think of it like a grid:
* Longitude (Meridian): Like the vertical lines on a grid, it tells you how far east or west a place is from the prime meridian (0 degrees longitude).
* Latitude: Like the horizontal lines on a grid, it tells you how far north or south a place is from the equator.
Example:
* New York City is located at approximately 74 degrees west longitude (meridian) and 40 degrees north latitude.
* Tokyo is located at approximately 139 degrees east longitude (meridian) and 35 degrees north latitude.
Therefore, you need both longitude and latitude to accurately determine the location of a place.
