Short Answers to Review Questions

• Coastal water in hotter, drier climate typically has higher salinity because less freshwater runs into the ocean in drier areas. Heat increases the evaporation rate.

• Technology used to study the ocean floor includes sonar and research vessels such as Alvin and Deep Flight.

• Sonar, research vessels and satellites are used to study the ocean floor.

• The two major regions of the ocean floor are the continental margin and the deep-ocean basin.

• They are all sections of the continental margin.

• Living resources- fish and seaweed

• Nonliving resources- oil and minerals

Short Answers to Study Guide
