What do horizontal lines on a grid system represent?

Horizontal lines on a grid system represent latitude. Latitude refers to the measurement of distance north or south of the Equator, which is designated as 0 degrees. As you move away from the Equator toward the poles, the latitude increases, reaching 90 degrees at the North Pole and -90 degrees at the South Pole.

Each of these horizontal lines on a grid is measured in degrees and helps to create a reference system that allows for precise location identification. This is essential for navigation, cartography, and geographical studies, as it defines how far a location is in relation to the Equator.

In contrast, longitude lines are vertical and indicate the distance east or west of the Prime Meridian. Elevation refers to height above a certain reference point, such as sea level, which is not represented by the grid lines themselves. Distance is a broader term that encompasses many geographical considerations and is not specifically related to the grid system's horizontal lines.
