Ocean surface salinity is the amount of salt found in the surface water of the world’s oceans. the image below shows four points marked on a world map, along with a color key representing the different ocean surface salinity levels (in grams of salt per kilogram of water). the color key ranges from purple, which shows areas having the lowest ocean surface salinity levels, to red, which shows areas having the highest ocean surface salinity levels.

which of the following is the best description of one of the regions shown on the map?
a.
region y is in an area where evaporation occurs at a relatively rapid rate.
b.
region z is in an area where condensation occurs at a relatively rapid rate.
c.
region x is in an area where condensation occurs at a relatively rapid rate.
d.
region w is in an area where evaporation occurs at a relatively rapid rate.
