Ocean Water

Check all of the ways salinity can decrease.

• Ocean water freezing near the poles.

• Fresh water entering the ocean via runoff.

• Precipitation occurring over the ocean mixing the rain and ocean water together.

• High amounts of ocean water evaporating near the equator.

• Rain entering a freshwater lake.
