Understanding Elevation and Sea Level

The video tutorial explains how to measure the height of a mountain using elevation, which is the height above or below sea level. It introduces the concept of positive and negative numbers on a number line, where numbers above zero are positive and those below are negative. The tutorial clarifies that sea level is zero elevation and provides examples of places above and below sea level, such as mountains, fish underwater, planes, and submarines. It also discusses how volcanoes can start below sea level and extend above it. The lesson concludes by reinforcing the relationship between positive and negative numbers and elevation.
