The Mid Atlantic Ridge is a divergent plate border where the North American Plate and the Eurasian Plate are migrating apart from one other.
Iceland is located on this plate boundary. About 16 million years ago, volcanic activity built the island, and volcanoes continue to develop, erupt, and influence Iceland’s landscape now.
There are about 100 volcanoes on the island, some of which are extinct, but roughly 30 of which are actively active.
Iceland is located on the tectonic plate boundary that divides the Eurasian and North American plates, known as the Mid-Atlantic Ridge. The ridge, which is an underwater mountain range, stretches for around 16,000 kilometers over the Atlantic Ocean’s north-south axis.
Plate tectonics creates a rift valley along its spine, which is the site of fresh crust development. Molten lava wells up from under the Earth’s crust, cools, and is pushed away from the ridge’s sides, deepening the distance between the continents.
Iceland was produced by the collision of the North American and Eurasian plates’ spreading boundaries, as well as a hotspot or mantle plume — an exceptionally hot rock increase in the Earth’s mantle. Excessive lava outbursts formed volcanoes and filled rift valleys as the plates drifted apart.
Later lava fields were rifted by subsequent movement, resulting in long, linear valleys defined by parallel faults. The ridge began to divide 150 million years ago in the north and 90 million years ago in the south.
These motions are still occurring now, and they are accompanied by earthquakes, the reactivation of ancient volcanoes, and the formation of new ones. Because of its size, Iceland is the biggest island on the ridge.
Iceland (102,775 km2) is the world’s biggest continent lying on an oceanic ridge. It’s a seafloor plateau located at the intersection of the Mid-Atlantic Ridge and the Greenland-Iceland-Faeroe Ridge. The oceanic divergent plate boundary between the North American Plate and the Eurasian Plate runs across it.
The Iceland Plate Boundary Zone is made up of segmented rift zones connected to the worldwide mid-ocean ridge system via transform zones.
Thingvellir, in the south of Iceland, is a good illustration of this, since it is where the North American and Eurasian tectonic plates meet, or rather, move away from one other. This is plainly visible from the ground at Thingvellir, a national park.
Iceland is home to a large number of volcanoes due to its location at the intersection of two tectonic plates. Tectonic plates are huge portions of the Earth’s crust that are found in the lithosphere layer. Extremely hot substances may rise from inside these plates since they are not fused.
