Answer 2

Ответ:

Longitude is a geographic coordinate that specifies the east-west position of a point on the Earth's surface. It is measured in degrees, minutes, and seconds east or west of the Prime Meridian, which is an imaginary line that passes through the Royal Observatory in Greenwich, London, England. The Prime Meridian is defined as 0° longitude, and it divides the Earth into the Eastern Hemisphere and the Western Hemisphere. Longitude lines run perpendicular to latitude lines, which measure north-south position, and they converge at the Earth's poles. Longitude is an important concept for navigation and timekeeping, as it enables us to determine our location on the globe and calculate the time difference between different points on the Earth's surface.
