Answer:
True
Step-by-step explanation:
Zero-reference point: As mentioned, the equator is indeed the zero-reference point for latitude. All other latitudes are measured in degrees north or south of the equator.
Determining location: Calculating latitude essentially determines the position of a point or phenomenon relative to the equator. It tells you whether it's north or south of the equator and at what angle or distance from it.
Degrees: Latitude is expressed in degrees, ranging from 0° at the equator to 90° north and 90° south. Positive values indicate north, while negative values indicate south.
Therefore, starting with the equator as the zero-reference point and assigning positive/negative values for north/south positions is essential for accurately calculating and interpreting latitude.
So, both points in the statement are true:
You must start with the equator as your zero-reference point.
You are determining whether your point location or phenomenon is north or south of the equator.
