A researcher collected a surface water sample from the locations marked A and B on the map above. Which statement below is the most reasonable hypothesis for why Sample B was higher in salinity than Sample A?
A:If the location is closer to the equator, then the salinity will be higher because the rate of evaporation is higher.
B:If the water is from the Pacific Ocean, the salinity will be lower.
C:If the location is closer to the equator, then the salinity will be lower because the rate of evaporation is higher.
D:If the water is more shallow, then the salinity will be higher.
I choose C
