Answered by GPT-5 mini AI
Iceland sits on a divergent (constructive) plate boundary — the Mid‑Atlantic Ridge — where the North American and Eurasian plates are moving apart. Magma rises in the rift, forming new crust and frequent volcanic activity. Iceland’s situation is amplified by a mantle plume (hotspot), which makes the ridge volcanically active and keeps much of the island above sea level (e.g., Þingvellir rift, Reykjanes Peninsula, Eastern Volcanic Zone).
