Knowra Iceland Iceland Iceland is a large North Atlantic island formed by volcanic activity along the Mid-Atlantic Ridge. It makes up most of the territory of the Republic of Iceland.
Mid-Atlantic Ridge : An underwater mountain system marking the boundary between the North American and Eurasian tectonic plates. The ridge crosses Iceland, where its spreading boundary rises above sea level.
Vatnajökull : Iceland’s largest ice cap, located in the southeast of the island. Its ice-covered volcanoes and glacial rivers dominate a vast part of Iceland.
Geology of Iceland : The study of Iceland’s rocks, landforms, and geological history. It traces how volcanic activity and plate spreading assembled the island.
Geothermal energy in Iceland : The use of underground heat to provide electricity and heating in Iceland. Volcanic heat makes geothermal resources widely available across the island.
Greenland : The world’s largest island, located between the Arctic and North Atlantic oceans. It is a much larger neighboring island, but lies across the Denmark Strait.
Iceland hotspot : A persistent region of unusually hot mantle that supplies magma beneath Iceland. Its interaction with the ridge helps explain Iceland’s unusually high volcanic output.
Þingvellir : A rift valley in southwestern Iceland where the North American and Eurasian plates pull apart. Its visible fractures make Iceland’s tectonic setting especially clear.
Iceland plume : A mantle plume proposed to underlie Iceland and contribute to its exceptional volcanism. The plume is one explanation for the island’s elevated crust and abundant magma.
Hydropower in Iceland : Electricity generation from Iceland’s rivers and glacial meltwater. Abundant precipitation, steep terrain, and glaciers support large hydropower resources.
Faroe Islands : A North Atlantic archipelago between Iceland, Norway, and Scotland. The Faroes share a remote North Atlantic setting but are separate from Iceland.
