Answer to Question 1

Answer: A

Answer to Question 2

Answer: Sea level could be lowered if the climate turned colder, causing more water to be tied up in glacial ice. This could drastically affect shallow water creatures (habitat destruction) and cause many extinctions. The colder climate could also cause the demise of some species through habitat destruction and scarcity of food. Sea level could also be lowered if seafloor spreading were to slow down.
