What are meridians and parrells?

Answer 1

lines of latitude are parallels and lines of longitude are meridians.

latitude lines are circles around the earth running east west (like equator)

longitude lines run north - south and they meet at two spots, the north pole and the south pole.

Meridians also determine the time at a location on the earth.

Answer 2

Meridians are imaginary lines that run from the North Pole to the South Pole on a map or globe, helping to indicate longitude. Parallels, on the other hand, are imaginary lines that run parallel to the equator, indicating latitude. Both meridians and parallels are used for navigation and mapping purposes.
