Q. Consider the following statements regarding coral reefs:- An atoll is a ring-shaped coral reef enclosing a lagoon.
- A barrier reef runs parallel to a coastline but is separated by a lagoon.
- A fringing reef always develops with a wide lagoon in between.
- An elongated atoll is an oval-shaped reef type.
Which of the above statements are correct?
Answer:
1, 2 and 4
Notes: Statements 1, 2, and 4 are correct. An atoll is a ring-shaped reef enclosing a lagoon; barrier reefs run parallel to coasts but are separated by a lagoon; and elongated atolls can be oval-shaped. However, fringing reefs are directly attached to the shore, often with minimal to no lagoon between the reef and land.
