What type of lines divide the Earth into latitudinal sections?

The correct choice refers to latitude, which consists of imaginary lines running parallel to the Equator. These lines are used to define the position of locations north and south of the Equator, which is a specific line of latitude itself located at 0 degrees. Latitude lines are measured in degrees, ranging from 0° at the Equator to 90° at the poles, thereby creating distinct latitudinal sections across the Earth. This division is crucial for navigation, meteorology, and geography, as it enables the identification of climate zones and influences weather patterns.

Longitude, meridian, and the Equator, while relevant to Earth's geography, do not divide the Earth into latitudinal sections. Longitude lines run from pole to pole and are used to define positions east and west, rather than influencing latitudinal sections. The term 'meridian' is synonymous with longitude lines. The Equator, while it represents a key line of latitude, does not encompass the entire system of dividing the Earth into latitudinal sections; it is merely one specific line among many. Thus, latitude comprises the full set of these parallel lines, making it the correct answer.
