There is much volcanic activity in iceland, and the country straddles the mid-atlantic ridge. therefore, iceland is situated a. over a hot spot b. over a subduction zone c. along a divergent plate boundary d. along a convergent plate boundary

Option (C)

Explanation:

In a divergent plate boundary, two plates move in the opposite direction. Due to this motion, the magma comes out to the surface of the ocean floor forming a mid-oceanic ridge. It leads to the formation of volcanoes and also generates deep-focus earthquakes.

Iceland is a country that is on the higher latitude, near the Arctic circle. This was formed some 20-25 million years back, due to the rapid and intensive volcanic eruptions that have taken place along the Mid-Atlantic Ridge. This country formed due to the separation of the North American Plate and the Eurasian plate.

Thus, the correct answer is option (C).

this age may represent the age of the earth's accretion, of core formation, or of the material from which the earth formed. this dating is based on evidence from radiometric age-dating of meteorite material and is consistent with the radiometric ages of the oldest-known terrestrial and lunar samples.
