It would be D. Water molecules are split apart and the byproduct of that would be the O2. As energy enters the chloroplasts, the energy excited the H2O molecules and causes them to split
Iceberg: The formation of icebergs increases salinity because it is taking liquid water out of the ocean without taking the salt.
Sea Ice: Same as icebergs, this increases salinity because it removes liquid water.
Runoff: This decreases salinity because it is introducing fresh water into the ocean, reducing the salt to water ratio.
Evaporation: This would increase salinity because it is removing liquid water from the ocean, increasing the salt to water ratio.
Hope this helps!
