Spot elevations are used to indicate what about a point?

• A. The point's distance from the equator
• B. The point's elevation relative to sea level
• C. The point's depth below the surface
• D. The point's slope angle

Answer: (B)

Spot elevations measure how high a point sits above mean sea level. They give a precise vertical position for that location, which helps describe the terrain’s height at a specific spot. This is different from latitude, which tells how far a point is from the equator; it’s not about depth below the surface, and it’s not about how steep the slope is between points. So a spot elevation tells you the point’s elevation relative to sea level—for example, a value of 500 feet means that point is 500 feet above mean sea level.
