Correct option is C
Introduction
The
Continental Shelf is the gently sloping, submerged extension of the continent. It is characterized by an extremely gentle gradient, with an average slope of approximately
0° 17' (about
0.28 degrees). Therefore, the most accurate description among the options is
one degree or less.
Information Booster
·
Definition: The underwater landmass that extends from a continent, resulting in an area of relatively shallow water.
·
Slope: The Continental Shelf is characterized by a very
gentle slope.
·
Average Gradient: The average slope is approximately
0° 17', which is significantly less than one degree.
·
Extent: It typically extends from the coast to the continental shelf break, where the slope dramatically increases to form the continental slope.
·
Economic Significance: It is home to most marine life, fishing grounds, and offshore oil and gas deposits.
Additional Points
·
Three degrees to five degrees,
five degrees to seven degrees, and
One degree to three degrees: These slope values are too steep. A slope of 3° to 7° is more characteristic of the much steeper
Continental Slope, not the shelf.
