The equator and the prime meridian are used on maps primarily **to provide a reference system**. They serve as the fundamental lines of latitude and longitude that help in locating points on the Earth’s surface.

1. **Equator**: This is the zero-degree line of latitude, which divides the Earth into the Northern and Southern Hemispheres.

2. **Prime Meridian**: This is the zero-degree line of longitude, which divides the Earth into the Eastern and Western Hemispheres.

Together, they create a grid system that allows for precise mapping and navigation, helping to measure distances and identify locations, including continents. They also play a role in separating the Earth into its four hemispheres (Northern, Southern, Eastern, and Western).
