Silfra fissure is part of the _____________________
Group of answer choices
A. East Pacific Rise
B. Mid-Atlantic Ridge
C. Juan de a Ridge
D. American-Antarctic Ridge
My thought is that it could be B
To determine the correct answer, we need to explore the location of Silfra fissure. Silfra fissure is a submerged crack or crevice located in Þingvellir National Park in Iceland. It is a popular diving and snorkeling spot that attracts visitors due to its crystal-clear waters.
Now, let's narrow down the answer choices:
A. East Pacific Rise: The East Pacific Rise is a mid-ocean ridge located in the eastern Pacific Ocean. It extends from the Gulf of California and merges with the Pacific-Antarctic Ridge. However, Silfra fissure is not located in this area.
B. Mid-Atlantic Ridge: The Mid-Atlantic Ridge is a mid-ocean ridge that separates the Eurasian and North American tectonic plates. It runs through Iceland and the Arctic Ocean. Silfra fissure is indeed part of the Mid-Atlantic Ridge, making option B a plausible answer.
C. Juan de a Ridge: The Juan de a Ridge is a spreading ridge located off the coast of British Columbia, Canada, and the Pacific Northwest of the United States. It is not related to Silfra fissure, so option C is unlikely to be the correct answer.
D. American-Antarctic Ridge: The American-Antarctic Ridge is a ridge located in the South Atlantic Ocean between South America and Antarctica. It is unrelated to the location of Silfra fissure, so option D is not the correct choice.
Considering the explanations above, the most accurate answer is B. Mid-Atlantic Ridge, as Silfra fissure is indeed part of this ridge system.
