The Equator is the zero reference for latitude.
The Prime Meridian is the zero reference for longitude.
The equator, and the prime meridian.
Latitude lines are lines that run East/West on the earth that separate the earth into 15 degree sections.
The Equator (zero latitude) that separates the Northern and the Southern Hemispheres, and the Prime Meridian (zero longitude) that separates the Western and the Eastern Hemispheres.
Lines of longitude, or meridians.
Longitude lines are the North/South lines that separate the earth in 15 degree sections. They are used for navigation.
The two imaginary baselines used to create a grid for locating points on Earth are the Equator and the Prime Meridian. The Equator is a line of latitude that divides the Earth into Northern and Southern Hemispheres, while the Prime Meridian is a line of longitude that divides the Earth into Eastern and Western Hemispheres. Together, these two lines help establish a system of coordinates for pinpointing locations on the Earth's surface.
The lines are marks for the sidelines, baselines, free throw lines, 3 point lines, mid-court circle, foul lanes, keys, and mid-court (10 second) line.
Longitude
The invisible lines around the earth are called lines of latitude and longitude. Lines of latitude run east-west and measure the distance north and south of the equator, while lines of longitude run north-south and measure the distance east and west of the Prime Meridian. These lines help in locating specific points on Earth's surface.
The lines are marks for the sidelines, baselines, free throw lines, 3 point lines, mid-court circle, foul lanes, keys, and mid-court (10 second) line.
Longitude
Longitude lines stay right where they are at ... on the surface of the Earth, joining the north and south poles.
