When you say longitude, your mouth makes a long vertical shape. When you say latitude, it forms a more horizontal smile. Therefore, longitude lines are from north to south and latitude lines are from east to west.

How do we use latitude and longitude?
One way to pinpoint a location is by using latitude and longitude coordinates. These coordinates are expressed as degrees that are divided into 60 minutes, with each minute divided into 60 seconds. Latitude tells the distance north or south of the Equator, which is the line that falls equally between the North and South Poles. Longitude lines tell the east-west position of a point and are perpendicular to the Equator and parallel to the Prime Meridian.
What is elevation?
Accurate locations take into account the third dimension, or height. The height above or below sea level is called elevation. Sea level is the average height of the ocean’s surface, and is the same all around Earth.
Elevation measures height
