Elevation is height compared to sea level. If the height of a landmass is below sea level, the elevation is negative. The lowest point in the United States is in Death Valley at Badwater Basin. It has an elevation of -86 meters. Plot the elevation of Badwater Basin on a number line. Be sure to include zero on your number line.
DOUBLE JEOPARDY QUESTION: What does zero represent in this context? (extra 200 points if correct)
86 meters LEFT or LOWER than zero
