Detailed explanation-1: -Longitude is the measurement east or west of the prime meridian. Longitude is measured by imaginary lines that run around Earth vertically (up and down) and meet at the North and South Poles. These lines are known as meridians. Each meridian measures one arc degree of longitude.

Detailed explanation-2: -The prime meridian separates the eastern hemisphere from the western hemisphere. Halfway around the world, at 180 degrees longitude, is the International Date Line. The prime meridian is the line of 0° longitude, the starting point for measuring distance both east and west around Earth.

Detailed explanation-3: -There are 360 degrees of longitude (+180° eastward and −180° westward.). The longitude line of 0 degrees is known as the Prime Meridian and it divides the world into the Eastern Hemisphere and the Western Hemisphere.
