Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

the sunlit top layer of the ocean beyond the continental shelves; the vast bulk of the sea, it covers over 360, 000, 000 square kilometers of the Earth’s surface and is referred to as the ‘marine desert’ because nutrients are lower here than in the shallow seas; life can be scarce

A	open ocean
B	aphotic zone
C	benthic zone
D	phytoplankton

Explanation:

Detailed explanation-1: -The epipelagic zone (1) is the sunlit upper layer of the ocean. It reaches from the surface to about 200 meters (660 feet) deep. The epipelagic zone is also known as the photic or euphotic zone, and can exist in lakes as well as the ocean. The sunlight in the epipelagic zone allows photosynthesis to occur.

Detailed explanation-2: -About 71 percent of the Earth’s surface is water-covered, and the oceans hold about 96.5 percent of all Earth’s water.

Detailed explanation-3: -The ocean has three primary layers. 2. The layers are the surface layer (sometimes referred to as the mixed layer), the thermocline and the deep ocean.

Detailed explanation-4: -Sunlight Zone. This zone extends from the surface down to about 700 feet. Twilight Zone. This zone extends from 700 feet down to about 3, 280 feet. The Midnight Zone. This zone extends from 3, 280 feet to 13, 125 feet. The Abyssal Zone. The Trenches. 26-Feb-2016
