Positive and Negative Numbers Above and Below Sea Level

This lesson explains how positive and negative numbers relate to elevation by examining distances above and below sea level. Elevation is defined as height, with sea level representing zero elevation. The video uses examples like mountains, fish, planes, and submarines to illustrate how elevation can be positive or negative. It also highlights that elevation is a comparison to sea level, which is the ocean's height. The lesson concludes with a volcano example, showing elevation from the ocean's bottom to its surface.
