normal pressure at sea level is 1 atmosphere of pressure (1 ATM). As you dive below sea level, the pressure changes. The mapping diagram represents the pressures at different depths.

Based on the graph, what would the output pressure be for 50 m?

• 6 ATM

• 5 ATM

• 7 ATM

• Need more information to determine the answer.
