Answer:
to provide a reference system
Explanation:
The equator and prim meridian used on maps provides a reference system for determining location and navigating the earth.
- An equator is the only line of latitude that is a great circle.
- Prime meridian is a line of longitude that is 0°
- When both are used, they can form the basis of a reference system to determine places on earth.
- Using these lines, we can assign values of coordinates to the earth surface to facilitate location determination.
The equator and prime meridian are used on maps to provide a reference system.
The limestone caves at Carlsbad Cavern were formed by hydrogen-sulfide-rich (H2S) waters. This water moved through fractures and faults in the limestone and mixed with rainwater along the way. The mixture gave rise to a substance known as sulfuric acid (H2SO4). Sulfuric acid is able to dissolve limestone, eventually creating Carlsbad Cavern. The process of cave formation ended roughly four million years ago.
