GEOLOGY

Detailed explanation-1: -The continental shelf is the extended margin of each continent occupied by relatively shallow seas and gulfs. It is the shallowest part of the ocean showing an average gradient of 1° or even less. The shelf typically ends at a very steep slope, called the shelf break.

Detailed explanation-2: -A continental shelf is the edge of a continent that lies under the ocean. Continents are the seven main divisions of land on Earth. A continental shelf extends from the coastline of a continent to a drop-off point called the shelf break.

Detailed explanation-3: -The sea floor below the break is the continental slope. Below the slope is the continental rise, which finally merges into the deep ocean floor, the abyssal plain.

Detailed explanation-4: -Extending out from a continent’s edge is a gently sloping, shallow area called the continental shelf (F). At the edge of the shelf, the ocean floor drops off in a steep incline called the continental slope (A).

Detailed explanation-5: -A continental shelf extends from the coastal area to the depths of around 100–200 meters (that is approximately 330–660 feet). They are gently inclined towards the sea at an average slope of approximately 0.1°.
