Why or why not? d) Assuming I did find atolls in the Bering Sea, would they be active or inactive and how could they have gotten there?

Explanation / Answer

1. Seamount is an underwater mountain formed by volcanic activity.Seamounts form by submarine volcanism. After repeated eruptions, the volcano builds upwards into shallower water.

2. A tools can be defined as a ring-shaped coral reef or a string of closely spaced small coral islands, enclosing or nearly enclosing a shallow lagoon. An atoll is an island formed by a ring-shaped coral reef encircling a lagoon. The word comes from the language of the Maldives, an island chain in the Indian Ocean famous for gorgeous beaches and coral reefs.

3.The Bering Sea is a marginal sea of the Pacific Ocean. It comprises a deep water basin, which then rises through a narrow slope into the shallower water above the continental shelves. There is no atoll can be found in the bering sea because Water temperatures on the surface average from 34° F (1° C) in the north to 41° F (5° C) in the south. The period without frosts lasts for about 80 days in the northern part of the sea, where snow is common even in the summer and maximum temperatures are only 68° F (20° C). And the temperature needed for the formation of the atoll is 25°c in average.

4. If there any one can found atoll in the bering sea that would be inactive and they found there by the internal forces of currents by which they move from one place to another (tropical to subtropical and polar) because atolls are formed in tropical areas where average temperatures ranges from 25°C and above.
