Thick, highly viscous lava.
2. Thick or runny lava. Thick flows slowly, runny flows faster.
No
A shield volcano. Generally they have runny lava that forms lots of thick layers. The Hawaiian island volcanos are good examples.
Lava is orange and runny
No. Lava hardens into rock.
Lava is a liquid. It is molten rock that flows like a thick fluid when erupted from a volcano.
runny lava
A composite volcano, also known as a stratovolcano, typically has a thick and viscous lava flow due to its high silica content. This type of volcano tends to erupt explosively, producing a mixture of lava, ash, and volcanic rocks.
silica content
Acid lava comes from composite cones,is slowly moving and viscous while basic lava comes from shield volcanoes,is non viscous, runny and flows faster
pumice
Silica and oxygen content in lava affects its viscosity, which in turn impacts flow speed. Lava with higher silica content tends to be more viscous and flows slower, while lava with lower silica content flows faster. The presence of oxygen also influences lava's ability to flow by affecting its gas content and pressure.
