Urban development increases demand for _________, especially after large storms or floods. Many islands are formed from underwat
er ________ activity. If a cliff is observed to have retreated from its previous location, this is due to _______. An abyssal hill is found in the _______. Deposition and ________ are two processes that cause sediment accumulation and give a shoreline its particular shape. Respond to the following based on your reading. Briefly describe how different types of reefs can form around an island.
As scientist has classified the reefs based on the following characters such as the fringe, barrier and atoll and patch reefs that can for the islands and thus create many physical features around the island.
The barrier reef is a reef that is roughly parallel to the shore and is separated by a lagoon and is pierced by the several channels and that provides access to this through the islands and the continent and the places are connected by it.
<u>While a fringe reef is one that is shallow ocean water and is based on the back reef zone and grows directly from the shoreline and is common to the Caribbean and the red sea. While the atoll is a ring shape or a horseshoe that encircles a lagoon partially or completely and is slowly formed by the corals.</u>
6. Reefs form from volcanic activity on an island in the ocean. This initially forms a fringing reef, but sea level rise can cause the reef to lie farther out from the island, forming a barrier reef. If the island ever subsides below sea level, the reef is called an atoll.
He based his calculations on the (then) widely held view that the early atmosphere was reducing, and concluded that the main constituents were methane (CH4), ammonia (NH3), hydrogen (H2), and water (H2O).
