What kind of boundary runs across iceland

Great volumes of meltwater, generated by subglacial eruptions, can burst out from beneath glaciers to produce enormous glacial floods called jokulhlaup. The discharge can be as much as 20 times greater than the flow rate of the Amazon River. The eruption at Laki was the largest single historic eruption of basaltic lava We have improved our tour selection from last year.

The Iceland hotspot and mighty geological phenomena Iceland sits spanning the Mid-Atlantic Ridge tectonic plate boundary which separates the Eurasian and the North American plates.

Volcanism in Iceland Because Iceland lies on the Mid-Atlantic Ridge, it is being split by the movements of the shifting tectonic plates. Landforms Iceland can be divided into three zones based on the age of the basaltic rocks. Volcanic eruptions Iceland is one of the most active volcanic regions on Earth.

What's more, Iceland is probably the only place in the world where the effects of two major tectonic plates drifting apart can easily be observed above sea level. The lithosphere consists of continental crust and oceanic crust that surfaces in the ocean basins. Simply termed, a tectonic plate, often also referred to as lithospheric plate, is a massive slab of solid rock that floats separately from the other tectonic plates, interacting with them along the boundaries.

The continents are embedded in the tectonic plates and drift inertly along. The reason that tectonic plates are able to move, despite their colossal weight, is that the two types of crust, continental and oceanic, differ significantly in composition. The continental crust is predominantly made up of granitic rocks, whilst the oceanic crust consists of higher density basaltic rocks therefore heavier , enabling the tectonic plates to float, not unlike icebergs.

The scientific theory of plate tectonics formulated in the s , which incorporates the concepts of continental drift and seafloor spreading, describes these large scale tectonic movements. The tectonic plates whose turbulent interactions formed Iceland, are the Eurasian tectonic plate and the North American tectonic plate. As the plates moved apart, excessive eruptions of lava constructed volcanoes and filled rift valleys. Subsequent movement rifted these later lava fields, causing long, linear valleys bounded by parallel faults.
