Answer to Question 1

ANS: C
These are common gases in our environment, but we are adding them into our atmosphere at an
alarming rate. There are also CFCs in the category of greenhouse gases. They all act as a glass roof
over Earth that traps heat inside the atmosphere. Information can be found in the section Human
Activity is Causing Global Oceanic Change.

Answer to Question 2

ANS: B
The tar remains behind when the volatile components evaporate. The wave action that is present then
causes the tar to clump together into small balls. Some of this tar falls to the bottom while other tar
gets taken up by organisms. Information can be found in the section Marine Pollutants May Be
Natural or Human Generated.
