Silfra is a rift valley that runs along part of the Mid-Atlantic Ridge in Iceland. This picture of Silfra shows an area where large cracks formed as the North American Plate and the Eurasian Plate moved away from each other. In this area, the rift cuts through an underwater spring, causing the cracks to fill with crystal-clear water. Because the water is so clear, it is a popular spot for scuba divers.

Okay. But what is the question then.

Answer 2

Answer:

Silfra is a fissure between the North American and Eurasian tectonic plates in Thingvellir National Park. The rift was formed in 1789 by the earthquakes accompanying the divergent movement of the two tectonic plates. The diving and snorkeling site at Silfra is right where the two continents meet and drift apart about 2 cm per year. Silfra is the only place in the world where you can dive or snorkel directly in a crack between two tectonic plates.
