Question

Which one of the following seas is without a coastline?
A) White Sea
B) Sargasso Sea
C) Sea of Okhotsk
D) Tasmania Sea

Answer 1

Hint: The coastline, which is a small strip of land that runs along the edge of a continent or an island and borders the sea, is an excellent site to view a continually changing landscape. Nothing ever stays the same because of the continual wave motion. Breakers nibble at cliffs, move sand, breach obstacles, construct walls, and shape bays. Even the tiniest ripples modify coastlines in a minute, minute ways—a few grains of sand at a time.

Complete answer:
The Sargasso Sea is the only sea without a land border, as it is wholly within the Atlantic Ocean. The Sargasso Sea is a large stretch of ocean named after the Sargassum genus of free-floating seaweed. While many varieties of algae may be found floating in the water all over the world, the Sargasso Sea is unusual in that it contains 'holopelagic' sargassum species, which means they not only float freely but also reproduce vegetatively on the high seas. Other seaweeds reproduce and start their lives on the ocean floor.

Sargassum is home to an incredible number of marine creatures. Sargassum mats serve as nurseries for turtle hatchlings, providing food and protection. Sargassum is also an important habitat for shrimp, crab, fish, and other marine creatures that have evolved to live in this type of floating algae. Threatened and endangered eels, as well as the white marlin, porbeagle sharks, and dolphinfish reproduce in the Sargasso Sea. Every year, humpback whales travel across the Sargasso Sea. Birds and commercial fish such as tuna migrate through the Sargasso Sea and rely on it for food.

Therefore the correct answer is option ‘B’.

Note: The Sargasso Sea is defined solely by ocean currents, unlike other seas in the world, which are delimited at least in part by land limits. The Northern Atlantic Subtropical Gyre encompasses it. The bounds of this area are dynamic, coinciding roughly with the Azores High-Pressure Center for any given season since it is defined by boundary currents.
