Here's a breakdown:
* Elevation: The vertical distance of a point on the Earth's surface above or below a reference level, typically sea level.
* Sea Level: The average level of the ocean's surface, used as a benchmark for measuring elevation.
There are different ways to express elevation:
* Absolute elevation: The height of a location directly above sea level.
* Relative elevation: The difference in height between two locations.
Example:
* Mount Everest's absolute elevation is 8,848.86 meters (29,031.7 feet) above sea level.
* The relative elevation between the top of Mount Everest and a nearby valley might be 5,000 meters (16,404 feet).
Important Note:
* While sea level is a commonly used reference point, there are other reference levels used for specific purposes, such as geodetic datums, which take into account the Earth's shape and gravity.
