The force behind the eruption of lava primarily comes from the pressure generated by gases dissolved in magma. As magma rises toward the Earth's surface, the decrease in pressure allows these gases to expand and form bubbles, increasing the pressure within the magma chamber. When the pressure becomes too great, it forces the magma to erupt through fissures or volcanic vents. Additionally, the viscosity of the magma can influence the eruption style, with more viscous magma often leading to more explosive eruptions.
What else can I help you with?
When volcano throws lava onto the air called?
When a volcano throws lava into the air, it is called a lava fountain or a lava fountain eruption. This happens when gas bubbles within the lava force it out of the volcano's vent, causing it to shoot upward in a fiery display.
A characteristic of lava that determines the force of a volcanic eruption is?
The silica content of the lava plays a key role in determining the force of a volcanic eruption. High silica content makes lava more viscous, leading to more explosive eruptions, while low silica content results in less viscous lava and less explosive eruptions.
What provides the force that propels magma from a volcanic vent?
Lava moves from its viscosity.
What is a river of lava called?
A river of lava is called a lava flow. It is a mass of flowing molten rock that moves downhill from a volcano during an eruption.
Lava is magma that has reached the what in an eruption?
Lava is magma that has reached the surface of the earth in an eruption. When this cools down, it will form igneous rocks.
How is lava bombs made?
Not a bomb in the usual sense- lava bombs are globs of lava formed inside of a volcano- blown out by the force of an eruption.
When volcano throws lava onto the air called?

How many people are killed during a volcano eruption?
Usually everyone in the way of the lava or the force of the eruption, unless everyone is evacuated.

What are the differences between pahoehoe and AA What kind of eruption produces these type of lava?
The differences are that Pahoehoe produces fast moving lava; Aa produces slower moving lava. The kind of eruption that produces these types of lava is a quiet eruption.
How can you use the word eruption and lava in a sentence?
The eruption of the boiling hot lava sent the small town into panic.
Is aa lava explosive lava?
No. A lava flow usually indicates an eruption that is not explosive.
What is a river of lava called?
A river of lava is called a lava flow. It is a mass of flowing molten rock that moves downhill from a volcano during an eruption.
Is lava considered weather?
Lava is not weather, it is the result of a volcano eruption. The eruption itself can cause weather issues such as falling ash and clouds, but lava is not considered "weather".
What makes a quiet eruption different from an explosive eruption?
quiet eruption flows easeir cause it has a low viscosity and lava flows easier but explosive eruption has a high viscosity and lava flows slower
Lava is magma that has reached the what in an eruption?
Lava is magma that has reached the surface of the earth in an eruption. When this cools down, it will form igneous rocks.
