Iceland is an example of ______.
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → Mid-oceanic Ridge
A mid-oceanic ridge is a long underwater mountain chain formed where two plates of the earth’s crust move apart and magma rises to fill the gap. Iceland lies on the Mid-Atlantic Ridge, between the North American and Eurasian plates, and is one of the few places where the ridge rises above sea level; its volcanoes and the rift valley that runs across the island come from this spreading.
Why the other options are incorrect
Option (1) Seamount — Incorrect. A seamount is an underwater volcanic mountain that does not reach the sea surface.
Option (3) Atoll — Incorrect. An atoll is a ring-shaped coral reef or island enclosing a lagoon, like many islands of Lakshadweep.
Option (4) Guyot — Incorrect. A guyot is a flat-topped seamount, its top worn down by waves before it sank below the sea.
