Chapter 11: Coastal Systems & Landforms

Question 1

Seawater Chemistry

Answer 1

The density of seawater generally increases with depth due to the weight of the overlying water. As depth in-creases, the temperature drops and salinity increases.

Question 2

Ocean Acidification

as the ocean absorbs excess carbon dioxide from the atmosphere.
A more acid ocean will cause certain marine organisms such as corals and some plankton to have difficulty maintaining external calcium carbonate shell structures
