Does a shield volcano have runny lava?
In volcanoes that have lower amounts of volcanic gases in the magma. A good example is the volcanoes in the Hawaiian islands. Volcanoes with more gases in the magma tend to erupt explosively (Mt. St. Helens, Vesuvius) and have a thicker, slower moving lava.
What are runny and sticky lava?
Runny lava contains low amounts of silicon, whereas sticky lava contains high amounts of silicon.
What causes lava to be runny and fluid?
Silica content of lava, as well as the temperature of the lava.
What are 3 types of volcanic mountains and explain?
Shield volcanoes are made from runny lava and steep sides. Cinder cone volcanoes are made from lava layers that alternate with layers of cinder. composite volcanoes shoot lav into the air.
Do shield volcanoes have high silica or low silica?
Shield volcanoes have low silica magma, which is more fluid and runny compared to magma with higher silica content. This low silica content contributes to the gentle, flowing eruptions characteristic of shield volcanoes.
What are Produced by volcanoes?
Shield volcanoes are produced by runny lava. That's why they have sloping sides and are like giant shields on the ground. The runny lava can't build up easily.
What are the characteristics of magma associated with shield volcanoes?
Basaltic, runny magma.

What are runny and sticky lava?
Runny lava contains low amounts of silicon, whereas sticky lava contains high amounts of silicon.
What type of magma causes quiet volcanoes?
magma that is low on silica & thin and runny & it flows easily

Silica content of lava, as well as the temperature of the lava.

Why shield volcanoes do not have steep sides but are still very tall?
shield volcanoes have gentle sides and aren't very tall
Do shield volcanoes have high silica or low silica?
Shield volcanoes have low silica magma, which is more fluid and runny compared to magma with higher silica content. This low silica content contributes to the gentle, flowing eruptions characteristic of shield volcanoes.
How are mars and earth volcano alike?
Like Earth, Venus has volcanic mountains and other features that are probably made of thin, runny lava, on Venus the volcanos sometimes spew out sulfur into the atmosphere, although there is no proof Venus is volcanically active, scientists believe it most likely is. On Mars there are large shields of volcanoes similar to those on Venus and Earth,as well as cone-shaped volcanoes and lava flows, some of these volcaoes are significantly bigger than Earth's volcanoes, such as Olympus Mons, which is 3 times the size of Mount Everest, but none of these are volcanically active.
What kind of lava forms shield volcanoes?
Shield volcanoes are fed by basaltic magma.
How is hawaiian lava different from composite cone lava?
Compared with the lava in composite volcanoes, hawaiian lava has a slow silica content, is runny, and erupts at a higher temperature.
