D. An atoll is created when tiny sea animals called corals slowly build a reef around an island that had been created by a volcano. Over millions of years, the volcanic island erodes and sinks to the sea floor, leaving a ring of coral reef that evolves into a single island or group of islets surrounding a lagoon.
B. The hermatypic corals that create the coral reefs cannot live in cold water around some volcanic islands. The area where where ocean temperatures are just warm enough for the corals to live is called the “Darwin point,” named after Charles Darwin. The famous naturalist was the first to outline how atolls form.
A. Between 1946 and 1958, the United States detonated 23 nuclear devices at the still radioactive Bikini Atoll. Four days after the first nuclear test, a French engineer introduced his new swimsuit design which he called the "bikini" because he hoped its revealing style would create an explosive reaction similar to the public response to the Bikini Atoll blast.
C. Since 1986, the Marshall Islands has been a independent republic in free association with the United States, with the U.S. providing defense, funding grants, and access to social services. U.S. forces seized the islands from Japan in World War II and ruled it as trust territory before it gained independence.
