Question

utilizing the graph provided, does river discharge or salinity have a higher variability? penobscot river and bay neither river discharge and salinity exhibit the any variability both river discharge and salinity exhibit the same variability salinity river discharge

Explanation:

Step1: Observe the graph

The blue - line (river discharge) ranges from about 275 m³/s to 675 m³/s. The orange - line (salinity) ranges from about 17 to 25.

Step2: Calculate the range for each

For river discharge, the range is \(675 - 275=400\) m³/s. For salinity, the range is \(25 - 17 = 8\).

Step3: Compare the ranges

Since \(400>8\), river discharge has a higher variability.

Answer:

River discharge
