1) What is one key property of plastic that makes it a threat to the ocean environment? a) It is not biodegradable and does not fully break down. b) It dissolves quickly in water, releasing toxins. c) It is heavier than water and sinks immediately. d) It attracts marine animals and causes them to congregate. 2) How do plastic bags commonly end up in the ocean? a) They are directly dumped into the ocean by individuals. b) They decompose on land and their residue flows into the sea. c) They are carried by sea birds from land to water. d) They get loose and travel through waterways like storm drains and rivers to the ocean. 3) Why is it difficult to remove microplastics from the ocean once they have formed? a) Because microplastics dissolve into the water instantly. b) Because microplastics disperse widely and are too small to be easily collected. c) Because microplastics float on the surface and are hidden under debris. d) Because marine animals protect microplastics from removal. 4) What is a "garbage patch" in the ocean? a) A land area contaminated by plastic waste from the ocean. b) A type of plastic designed to float on the sea surface. c) A large collection of floating plastic debris in circular ocean currents called gyres. d) A coral reef heavily damaged by plastic pollution. 5) What role do organizations like Ocean Cleanup and Clear Blue Sea play? a) They manufacture biodegradable plastic alternatives. b) They work to remove plastic waste from the ocean. c) They promote dumping of plastic in designated ocean zones. d) They fund plastic production companies to reduce costs. 6) Why doesn't the distance someone lives from the ocean prevent plastic from reaching it? a) Because plastic breaks down completely before reaching the ocean. b) Because plastic is only produced near oceans. c) Because most plastic in the ocean originates from ships only. d) Because plastic can travel long distances through waterways like rivers and storm drains. 7) What happens to plastic after it takes hundreds of years to decompose? a) It breaks down into smaller pieces called microplastics but does not fully disappear. b) It converts into harmless natural substances like water and carbon dioxide. c) It turns into new plastic products through natural recycling. d) It sinks to the ocean floor and becomes harmless sediment. 8) What is one of the main reasons it’s easier to prevent plastic pollution than to clean it up? a) Because ocean currents naturally remove plastic on their own. b) Because plastic pollution breaks down quickly on the ocean surface. c) Because plastic dissolves in saltwater and disappears. d) Because collecting large plastic pieces is easier than removing dispersed microplastics. 9) According to the video, what causes plastic debris to accumulate into large islands in the ocean? a) Circular ocean currents called gyres concentrate floating plastic debris. b) Large storms push plastic debris to specific ocean locations. c) Marine animals collect plastic debris together on the surface. d) Plastic naturally sinks and collects on the ocean floor.
