- Gas is part of the magma and gets released during the eruption.
- Magma, once it is above ground, is called lava. Lava from one volcano might act very differently from lava from another volcano, based on the viscosity of the lava.
- And finally, tephra is the solid material that gets ejected, like ash and rock.
The composition of magma (silica content), the amount of dissolved gases in the magma, and the temperature of the magma are three key factors that can influence the explosivity and style of a volcanic eruption.

When magma escapes from the mantle to the sufrface of earth it causes a?
volcanic eruption
Identify and explain the 3 factors that effect the force of a volcanic eruption?
The three main factors that affect the force of a volcanic eruption are the viscosity of the magma (more viscous magma results in more explosive eruptions), the amount of gas dissolved in the magma (higher gas content leads to more explosive eruptions), and the presence of a plug in the volcanic vent which can build up pressure and lead to a more violent eruption.
Magma that is rejected during a volcanic eruption forms igneous rocks?
Magma that is ejected during a volcanic eruption forms extrusive igneous rocks. They are also referred to as volcanic rocks.
Is Magma pockets the violent volcanic eruption?
yes
What factors determine the force of a volcano eruption?
Factors that determine the force of an eruption are magma viscosity and gas content.
What are the two important factors that affect the explosiveness of a volcanic eruption?
Pressure and magma
What about magma affects how explosive an eruption will be?
The composition of the magma affects how explosive a volcanic eruption will be.
When magma escapes from the mantle to the sufrface of earth it causes a?
volcanic eruption
What are three factors that affect the violence of a volcanic eruption?
Three factors that affect the violence of a volcanic eruption are the composition of the magma (viscosity and gas content), the location of the eruption (proximity to populated areas), and the type of volcano (shield, cinder cone, stratovolcano).

What is the relationship between the amount of gases in magma and the explosiveness a volcanic eruption?
The more gases, water vapor and silica there is in magma the bigger the explosiveness of a volcanic eruption.
What happens to the magma that leads to volcanic eruption?
blast
Is Magma pockets the violent volcanic eruption?
yes
What may precede a volcanic eruption?
Earthtremors.
What determined how strong a volcanic eruption will be?
The viscosity of the magma
What are two type of volcanic vents?
magma or lava dried after a volcanic eruption.
