D Correct answer
Explanation

The Indian Ocean is the only ocean named after a country, that is, India. The shape of the ocean is almost triangular. In the north, it is bound by Asia, in the west by Africa and the east by Australia. The Indian landmass has a central location between the East and West Asia. India is a southward extension of the Asian continent. The trans-Indian Ocean routes, which connect the countries of Europe in the West and the countries of East Asia, provide a strategic central location to India. No other country has a long coastline on the Indian Ocean as India has and indeed, it is India’s eminent position in the Indian Ocean, which justifies the naming of an Ocean after it.

C Correct answer
Explanation

The process of subduction produces a trench in sea.
The process by which ocean floor sinks beneath a deep-ocean trench and back into the mantle is called subduction (sub duk shun). As subduction occurs, crust closer to a mid-ocean ridge moves away from the ridge and toward a deep-ocean trench. Sea-floor spreading and subduction work together.

Salinity of Black sea is _____.

  1. 17%

  2. 18%

  3. 19%

  4. None of these

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The upper flow leaves the Black Sea and carries surface water out of it. Meanwhile a bottom flow carries salt water, about 35‰ from the Mediterranean to the Black Sea. The salty water mixes with the waters of the basin proper and that results in a comparatively low salinity at the surface, about 17%.
