Explain How Glaciers And Volcanoes Can Exist On Iceland?
There have been many volcanic eruptions both before and after the time when Iceland was settled. Many of Iceland´s active volcanoes are situated beneath glaciers. … The interaction between boiling magma and glacial ice can cause a jökulhlaup whether or not the red-hot lava has broken through the surface of the ice.
Why does Iceland exist?
Is Iceland made of volcanoes?
Iceland’s entire surface is made of volcanic rock most of it basalt — the rock that forms when lava cools. Iceland’s towering cliffs and jagged islands and reefs are all made of basalt.
How Iceland was formed?
Iceland formed by the coincidence of the spreading boundary of the North American and Eurasian plates and a hotspot or mantle plume – an upsurge of abnormally hot rock in the Earth´s mantle. As the plates moved apart excessive eruptions of lava constructed volcanoes and filled rift valleys.
What type of plate boundary created the volcanoes of Iceland?
Spanning the Mid-Atlantic Ridge Iceland emerged as a result of the divergent spreading boundary between these two plates and the activity of Iceland´s own hotspot or mantle plume. As the plates moved apart excessive eruptions of lava constructed volcanoes and filled rift valleys.
What causes volcanoes in Iceland?
The reason that there are so many volcanoes in Iceland is that the country lies where two tectonic plates meet. … Since these tectonic plates are divergent meaning they are pushing away from one another there is a natural pull that forces the flow of magma from the mantle to the Earth’s surface.

What is under Iceland driving the volcanoes?
Many of Iceland´s active volcanoes are situated beneath glaciers. These eruptions are called subglacial eruptions which often create massive and very destructive glacial floods known as jökulhlaups.
Why is Iceland so geologically active?
Iceland is one of the most active volcanic regions on Earth where almost all types of volcanic and geothermal activity can be found. The volcanism on Iceland is attributed to the combination of the Iceland plume hotspot activity and the Mid-Atlantic Ridge activity. The Mid-Atlantic Ridge is visible on land.

How hot is lava?
The temperature of lava flow is usually about 700° to 1 250° Celsius which is 2 000° Fahrenheit. Deep inside the earth usually at about 150 kilometers the temperature is hot enough that some small part of the rocks begins to melt. Once that happens the magma (molten rock) will rise toward the surface (it floats).
