hypothesis for how oceans properties differ from freshwater

Answer 1

The hypothesis is that oceans have a higher salinity level, a greater density, a higher buoyancy force, a greater pH level, and a higher concentration of dissolved gases than freshwater. These differences are due to the presence of various chemical substances including salts, minerals, and pollutants, which are primarily carried by rivers and streams into the oceans. These properties have a significant impact on the types of organisms that can survive in each environment and the overall ecological dynamics of these ecosystems.
