What is Surtsey made of?

Answer 1

• The island of Surtsey did not exist until the 14th of November 1963*
• Surtsey is Icelandic and means "Surtur's Island"
• The source of the lava that formed Surtsey was the Mid-Atlantic-Ridge (MAR). The MAR is part of a system of Mid-Ocean-Ridges that together form the longest mountain chain on Earth.
• The islands mode of formation (eruption of lava into water) means that the rock (known as Scoria) is very easily weathered and eroded meaning that the island has decreased in size ever since the volcanic eruption stopped.

*This was the day when the solidified lava from an undersea eruption just south of Iceland first broke the surface of the Atlantic.

Surtsey is a volcanic island off the southern coast of Iceland. It was formed in a volcanic eruption which began 426 ft below sea level, and reached the surface on 14 November 1963. The eruption lasted until 5 June 1967, when the island reached its maximum size.

Answer 4

Surtsey is made primarily of volcanic rock, including basalt and tuff. The island emerged from the Atlantic Ocean in 1963 due to an underwater volcanic eruption. Over time, weathering and erosion have shaped the island's landscape.

Answer 5

It was an explosion from the island Surtur
