Ocean Water and Climate Change

1. Which is more dense: ocean water or fresh water, and why?

 - Ocean water is more dense than fresh water because the salt in the seawater makes it denser than the fresh water.

2. How would global warming change water at the poles and the equator?

 - Global warming could affect storm formation by decreasing the temperature difference between the poles and the equator. Warmer temperatures could increase the amount of water vapor that enters the atmosphere. The equator where conditions are already hot and humid, at the poles the air is cold and dry.
