Which term best describes height above sea level?

Which term best describes height above sea level?

• A. Elevation
• B. Height
• C. Altitude
• D. Depth

Answer: (A)

Elevation is the term that specifically describes how high a point on the Earth’s surface sits above mean sea level. This standard reference lets maps, GPS, and geographic data consistently convey terrain height. Height is a more general word that doesn’t fix the reference level. Altitude is also used for height above a surface but is common in aviation and can refer to different reference frames (above sea level or above ground) depending on context, which can cause ambiguity. Depth refers to how far below the surface something lies, so it’s not about height above sea level. So, for height above sea level, elevation is the most precise and consistently used term.
