Flotsam Jetsam

What is the primary difference between flotsam and jetsam in marine environments?

• Flotsam is floating debris from a shipwreck, while jetsam is deliberately discarded cargo.

• Flotsam is found in freshwater, while jetsam is found in saltwater.

• Flotsam is natural debris, while jetsam is man-made.

• Flotsam is found on the ocean floor, while jetsam floats on the surface.

Which of the following best describes the ecological impact of flotsam and jetsam?

• They provide essential nutrients for marine life.

• They can be harmful pollutants affecting marine ecosystems.

• They are beneficial for coral reef formation.

• They have no significant impact on marine environments.

How can scientists track the movement of flotsam in the ocean?

• By using satellite imagery and ocean current models.

• By deploying underwater drones to follow the debris.

• By tagging the debris with GPS devices.

• By analyzing the chemical composition of the debris.

What scientific principle explains why flotsam floats on water?

• Archimedes' principle of buoyancy.

• Newton's third law of motion.

• The principle of conservation of mass.

• Bernoulli's principle of fluid dynamics.

Which experiment could help determine the origin of jetsam found on a beach?

• Chemical analysis of the material composition.

• Measuring the temperature of the water.

• Observing the color of the debris.

• Counting the number of items found.

What role do ocean currents play in the distribution of flotsam and jetsam?

• They help concentrate debris in specific areas like the Great Pacific Garbage Patch.

• They prevent debris from reaching coastal areas.

• They dissolve the debris over time.

• They have no effect on the movement of debris.
