What volcanic rock solidifies from low viscosity lava?
Basalt.
What provides the force that propels magma from a volcanic vent?
Lava moves from its viscosity.
Is pyroclastic material likely to form from low-viscosity lava?
No, pyroclastic material is not likely to form from low-viscosity lava. Low-viscosity lava typically flows easily and tends to produce effusive eruptions characterized by lava flows rather than explosive eruptions. Pyroclastic materials, such as ash and volcanic rocks, are more commonly associated with high-viscosity lava, which traps gas and leads to explosive volcanic activity.
Is the lava from Mount Rainier high or low vicosity?
The lava from Mount Rainier tends to have higher viscosity due to its composition, which includes more silica and other dissolved gases. This higher viscosity can lead to the lava flowing more slowly and forming steeper volcanic features.
How does water affect the viscosity of lava?
Water can decrease the viscosity of lava by disrupting the molecular structure of the magma, causing it to flow more easily. This can lead to more explosive and potentially dangerous volcanic eruptions. Conversely, in some cases water can increase the viscosity of lava, resulting in a slower flow.
What volcanic rock solidifies from low viscosity lava?
Basalt.
What is the relationship between the viscosity of andesitic lava and its flow behavior during volcanic eruptions?
The viscosity of andesitic lava affects its flow behavior during volcanic eruptions. Higher viscosity lava flows more slowly and tends to form thicker, blockier lava flows, while lower viscosity lava flows more easily and can travel further before solidifying. This relationship influences the type and intensity of volcanic eruptions.
What volcanic features does a volcano have?

What are formed when the lava and ash escapes at the surface?
Volcanic landforms and features.

How would you describe lava with a high viscosity?
Lava with high viscosity is thick and slow-moving, resembling thick honey or toothpaste. It tends to flow more sluggishly and can build up pressure, leading to explosive eruptions with volcanic ash and debris.
What eruption products are from mt kilauea?
Eruption products from Mount Kilauea include lava flows, volcanic gases (such as sulfur dioxide), ash, and volcanic tephra (fragments of volcanic rock). Lava flows are the most common product and can vary in composition from low-viscosity basaltic lava to more viscous and explosive lava compositions.
