Iceland is an example of __________.

Option 1 -> Seamounts are underwater volcanic mountains that don't reach the ocean surface, not applicable to Iceland.

Option 2 -> Iceland sits directly on the Mid-Atlantic Ridge where the North American and Eurasian plates diverge, making it a rare above-water example.

Option 3 -> Atolls are ring-shaped coral reef formations, typically found in tropical waters, not relevant to Iceland.

Option 4 -> Guyots are flat-topped underwater seamounts, submerged features unlike Iceland.

Hence, Mid-oceanic Ridge -> Iceland is located on the Mid-Atlantic Ridge, one of the few places on Earth where a mid-oceanic ridge rises above sea level due to intense volcanic activity from the divergent plate boundary -> correct
