Yes, people can have a significant impact on atolls through activities such as overfishing, pollution, and coastal development. These activities can disrupt the fragile ecosystem of atolls, leading to coral reef degradation and loss of biodiversity. Rising sea levels and climate change also pose threats to atolls and the communities that depend on them.
Atolls are created from coral reefs that grow on the rims of submerged volcanic islands. As the islands erode over time, the coral reefs continue to grow upward to maintain a balance between erosion and coral growth. This process prevents the atolls from sinking.
Most atolls are located in the Pacific Ocean, particularly in the South Pacific region. They are commonly found in areas with warm, clear waters and are often associated with coral reef systems. Additionally, atolls can also be found in the Indian Ocean and the Caribbean Sea.
Bryan (1953) lists about 400 atolls. The full article is available through http://www.botany.hawaii.edu/faculty/duffy/arb/019-23/v019-23.pdf. This is not a definitive list as the definition of an atoll is still the subject of discussion discussion. Bryan, E.H., 1953. Check list of atolls. Atoll Res. Bull., 19: 1-38.
Tuvalu consists of 9 coral atolls and 1 reef island.
These atolls are both in the Marshall Islands.
No, the word atolls is the plural form for the singular noun atoll. Example:There are a number of atolls on the coast near my home.
Atolls are formed first as a reef that fringes a volcanic island. The two largest atolls are Suvadiva in the Maldives Island and Kwajalein in the Marshall Islands.
