Question 5

True or false: The Sargasso Sea is the deepest sea in the world, reaching over 11,000 meters.

Accepted Answer

False. The Sargasso Sea has an average depth of about 5,000 meters. The deepest point on Earth is the Mariana Trench in the Pacific, over 11,000 meters.

Question 6

True or false: The Sargasso Sea is located entirely within the Bermuda Triangle.

Accepted Answer

False. The Sargasso Sea covers roughly 2 million square miles, while the Bermuda Triangle is a smaller triangular zone within its western portion.

Question 9

True or false: The Sargasso Sea is bounded by four major ocean currents that form the North Atlantic Gyre.

Accepted Answer

True. The Gulf Stream, North Atlantic Current, Canary Current, and North Atlantic Equatorial Current encircle the Sargasso Sea, creating a calm, stable region.

Question 10

True or false: Sargassum seaweed in the Sargasso Sea is toxic to marine life and forms dead zones.

Accepted Answer

False. Sargassum actually provides vital habitat and nursery grounds for eels, turtles, fish, and crabs. It's not toxic.

Question 11

True or false: The Sargasso Sea was first named by Christopher Columbus in 1492.

Question 14

True or false: The Sargasso Sea serves as a spawning ground for both American and European eels.

Accepted Answer

True. Both the American eel (Anguilla rostrata) and European eel (Anguilla anguilla) migrate to the Sargasso Sea to spawn. Their larvae drift back to freshwater.

Question 15

True or false: The Sargasso Sea is a freshwater sea because of the high concentration of Sargassum.

Accepted Answer

False. The Sargasso Sea has typical oceanic salinity (about 35 ppt). Sargassum is a marine seaweed that lives in saltwater, not freshwater.

Question 16

True or false: American eels migrate thousands of miles to spawn and die in the Sargasso Sea.

Accepted Answer

True. Both American and European eels travel from freshwater rivers to the Sargasso Sea to reproduce, then die. Their larvae drift back to continents.
