What Kind of Plate Boundary Runs Across Iceland?

General

Did you know that in addition to an oceanic trench and a continental rift, there is also a mid-ocean ridge (i.e., the Atlantic Ridge) made up of different volcanoes in Iceland? The island itself is formed by this mid-ocean ridge. Suppose you are interested in the collision of plates, plate boundaries, or plate tectonics. In that case, today’s blog post may be of interest to you!

Iceland is a volcanic island that rises out of the North Atlantic Ocean and lies between Europe and Greenland. It is 1,000 kilometers long and 200 kilometers wide and is 1,200 meters high. Because Iceland sits on the North American plate, it is not entirely isolated from the rest of the North American plate, which lies beneath it. Iceland sits on top of the North American plate and is not part of the Eurasian plate.

Iceland is pushed upward by the North American plate at the northern coast, which pushes on the Eurasian plate beneath the island. The Eurasian plate pushes back against the North American plate.

The mid-Atlantic ridge is located along the floor of the Atlantic Ocean, and it’s also the most extended mountain range in the world.

Plate boundaries are the meeting points of moving plates in Earth’s lithosphere. There are three kinds of plate boundaries: convergent, divergent, & transform. Divergent boundaries are found at the center of the Earth’s tectonic plates, where they are pulling away from each other. 

This creates high stress in the lithosphere, which can cause earthquakes. Convergent boundaries are found on the edges of the plates where they are colliding with each other. Again, the stress in the lithosphere causes earthquakes in this region. Transform boundaries occur when two plates slide by each other laterally in opposite directions.

The MAR or the Mid-Atlantic Ridge is a mid-ocean ridge, a divergent tectonic plate border located along the floor of the Atlantic Ocean and the longest mountain range in the world. In addition to a length of 30,000 miles, the Mid-Atlantic Ridge is more than twice as long as the Appalachian and the Rockies combined and more than three times as long again as the Himalayas.

The ridge is a triple-junction (an intersection of three tectonic plates), which allows ocean water to circulate, producing volcanic activity 120 million years ago.

Today, the Mid-Atlantic Ridge is primarily a research area, with most of the significant oceanographic institutes in the world having stations there.

However, the ridge is still an active volcano, with eruptions occurring at intervals of about 20 years. The most recent eruption occurred in 1988 and 1989.

The Mid-Atlantic Ridge is an active volcano where it crosses the Mid-Atlantic Ridge belt. The volcanoes formed on and near this zone are called the Volcanic Arc.

Conclusion

The Mid-Atlantic Ridge is a complicated structure. Along the west coast of Iceland, it extends out as a narrow ridge. On the east coast, it extends as a fan. The ridge is about 4 km wide, and the fan is about 30 km wide.

The Mid-Atlantic Ridge extends north into the North Atlantic, forming a deep channel called the Iceland Basin. At 3 km deep, the Iceland Basin is the deepest part of the ocean. The Iceland Basin is about 2,500 km long.
