A Rift Valley and Fissure in Iceland - What happens at divergent tectonic plate boundaries?

What happens at a divergent tectonic plate boundary? Iceland shows us a great example of a continent being pulled apart as the plates move away from each other. www.teacherspayteachers.com/P...
A divergent boundary occurs when two tectonic plates move away from each other. Along these boundaries, earthquakes are common and magma (molten rock) rises from the Earth's mantle to the surface, solidifying to create new oceanic crust. The Mid-Atlantic Ridge is an example of divergent plate boundaries.
As the plate stretches and thins, the underlying asthenosphere flows upward and expands like a hot-air balloon, lifting the region to higher elevations.
The continental crust breaks along faults, forming long mountain ranges separated by rift valleys.
The enormous Almannagjá gorge marks the edge of the North American plate and the beginning of the Þingvellir rift valley. The Rift Valley is partly filled with groundwater and carries Iceland's largest natural lake.
Þingvallavatn.
Þingvellir National Park is located in an active volcanic area just 49 km east of Reykjavík, the capital of Iceland, and covers 24,000 ha, of which 9,270 ha constitute the World Heritage property. Its best-defined feature is a major rift, which has produced dramatic fissures and cliffs demonstrating inter-continental drifting spectacularly and understandably. The National Park is enclosed by a varied belt of mountains on three sides, featuring grass-covered lava fields, and Lake Þingvallavatn lies at its southern end. #earthscience #tectonicplates #riftvalley #platetectonic

This is so pretty!
