What type of magma does Eyjafjallajokull have?

What type of magma does Eyjafjallajokull have?

Eyjafjallajokull volcano is considered a stratovolcano. What this means is that it’s a conical volcano built over time by layers of various volcanic materials. Black hardened lava, volcanic ash, pumice rock, and tephra fragments all combine to form different stratified colors and textures.

What type of magma is in Iceland?

basaltic lava
characteristics. The Icelandic type is characterized by effusions of molten basaltic lava that flow from long, parallel fissures. Such outpourings often build lava plateaus.

What type of volcano has liquid magma?

Shield volcanoes
Shield volcanoes Where a volcano produces low viscosity, runny lava, it spreads far from the source and forms a volcano with gentle slopes: a shield volcano. Most shield volcanoes are formed from fluid, basaltic lava flows. Mauna Kea and Mauna Loa are shield volcanoes.

Why was eyjafjallajokull so explosive?

As the ice started to melt, glacial water began flooding into the volcano where it met the bubbling magma at the centre of the eruptions. This rapid cooling caused the magma to shear into fine, jagged ash particles.

Is Eyjafjallajökull a shield or composite volcano?

IS EYJAFJALLAJOKULL A COMPOSITE VOLCANO? Yes. A composite volcano is just another word for stratovolcano. This means that the volcano is made up of layers of ash, lava, and solid stone.

What type of volcano is Krakatoa?

stratovolcano
Mount Krakatoa is an example of a stratovolcano, a tall, conical volcano with multiple strata of solidified lava, tephra, as well as volcanic ash. These type of volcanoes typically have steep sides and usually erupt frequently & violently. Most of the popular eruptions have been made by stratovolcanoes.

Does Greenland have a volcano?

There are no active volcanoes in Greenland, nor are there any known mapped, dormant volcanoes under the Greenland ice sheet that were active during the Pliocene period of geological history that began more than 5.3 million years ago (volcanoes are considered active if they’ve erupted within the past 50,000 years).

Is there a super volcano in Iceland?

Iceland’s Katla is one of the world’s most powerful volcanoes. The home of the Katla volcano is Mýrdalsjökull (Myrdalsjokull) glacier, the southernmost glacier in Iceland, almost 600 km2 large, and the 4th biggest glacier in Iceland.

What is lava magma?

Scientists use the term magma for molten rock that is underground and lava for molten rock that breaks through the Earth’s surface.

What are types of magma?

The high temperatures and pressure under Earth’s crust keep magma in its fluid state. There are three basic types of magma: basaltic, andesitic, and rhyolitic, each of which has a different mineral composition.

Is Eyjafjallajökull a hotspot?

Eyjafjallajokull was formed in two ways: by the divergent plate boundary intersecting Iceland and a hotspot that scientists believe resides under the boundary. Therefore, its height is due to the bubbling up magma from the boundary and its explosiveness is due to the hotspot.

What type of plate boundary is Eyjafjallajokull?

Eyjafjallajokull Formation Eyjafjallajokull was formed in two ways: by the divergent plate boundary intersecting Iceland and a hotspot that scientists believe resides under the boundary. Therefore, its height is due to the bubbling up magma from the boundary and its explosiveness is due to the hotspot.
