Why is basalt The type of lava that forms shield volcanoes?
Shield volcanoes are formed by lava flows of low viscosity – lava that flows easily. Consequently, a volcanic mountain having a broad profile is built up over time by flow after flow of relatively fluid basaltic lava issuing from vents or fissures on the surface of the volcano.
How Shield volcanoes are formed?
A shield volcano is a type of volcano named for its low profile, resembling a warrior’s shield lying on the ground. It is formed by the eruption of highly fluid (low viscosity) lava, which travels farther and forms thinner flows than the more viscous lava erupted from a stratovolcano.
Which lava types are likely to form shield volcanoes?
Shield volcanoes have the following characteristics: Basaltic magma, which is high in temperature, very low on silica and with low gas content. This type of magma produces fluid lava with very little explosive activity. Basic lava, which is non-acidic and very runny.
Does basic lava form a shield volcano?
Shield volcanoes are found on constructive plate margins , where two plates move away from one another. Shield volcanoes have the following characteristics: basic lava, which is non-acidic and very runny. gentle sides as the lava flows for long distances before it solidifies.
What is the largest shield volcano on Earth?
Do shield volcanoes explode?
Eruptions at shield volcanoes are only explosive if water somehow gets into the vent , otherwise they are characterized by low-explosivity fountaining that forms cinder cones and spatter cones at the vent, however, 90% of the volcano is lava rather than pyroclastic material. …
Is Fujiyama a shield volcano?
The 3,776-meter-high (12,388 feet) Mount Fuji Volcano, located on the island of Honshu in Japan, is one of the world’s classic examples of a stratovolcano. (Low-viscosity flows spread out over the landscape and build lower-profile shield volcanoes.) ..
What is the shortest lived type of volcano?
Are shield volcanoes dangerous?
The lava flow from a shield volcano eruption is largely composed from basaltic magma. The lava features a low viscosity and erupts in a relatively gentle stream. Therefore, shield volcano eruptions generally do not pose a threat to human lives, as the lava flow is easy to predict and avoid

Is Mt Everest still growing?
Growth of Everest The Himalayan mountain range and the Tibetan plateau were formed as the Indian tectonic plate collided into the Eurasian plate about 50 million years ago. The process continues even today, which causes the height of the mountain range to rise a tiny amount every year.

Was Everest underwater?
