Volcanoes can have runny or sticky molten rock which one is fairly safer?

Sticky magma is more dangerous. The more viscous magma tend not to come out as lava flows, but often come out explosively, producing fast-moving avalanches of hot ash and gas called pyroclastic flows.

Runny molten rock (low viscosity) is generally safer because it flows more easily and allows people to move out of the way faster. Sticky molten rock (high viscosity) tends to trap gases and pressure, leading to explosive eruptions.

What are runny and sticky lava?
Runny lava contains low amounts of silicon, whereas sticky lava contains high amounts of silicon.
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 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.
How do you know that many of the volcanoes in the western district of Victoria had runny lava?
Many of the volcanoes in the western district of Victoria had runny lava because they were created from basaltic magma, which has a lower viscosity compared to other types of magma. This lower viscosity allowed the lava to flow easily and spread over large areas, resulting in the formation of broad shield volcanoes with gently sloping sides.
What are runny and sticky lava?
Runny lava contains low amounts of silicon, whereas sticky lava contains high amounts of silicon.
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.

Is basaltic lava sticky or fast running?
well, since basaltic lava is the same material that composes the ocean floor, it is common sense that it would be sticky, not runny.
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.

What is the texture of honey?
Honey has a thick and sticky texture, similar to syrup. It can range from smooth and runny to creamy or crystallized, depending on factors such as temperature and processing.
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.
