Question

Which condition would cause salinity of ocean water to decrease

A. High rates of evaporation
B. Freezing of glaciers
C. Extremely hot weather
D. A river flowing into the sea

Answer 1

Yupp cause water expands when frozen but extreme heat would cause a lot to evaporate so the water wouldn’t completely disappear but it would lower sea levels and the water would be extra salty

Answer 2

D. A river flowing into the sea

The freezing of glaciers would do nothing to the salinity. Hot weather on the other hand, and evaporation, would leave behind the salt and thus it Increases the amount of salt to water in the ocean.
