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
Identify and explain the 3 factors that effect the force of a volcanic eruption?
The silica content effects the force of a volcanic eruption because magma with a lot of silica is thicker and magma with less silica is thinner. The amount of dissolved gases in magma effects the force of a volcanic eruption because the less gas in the magma, the less pressure will be inside the volcano. The temperature of the magma effects the force of a volcanic eruption because the hotter the magma, the more runny it is.
What is an opening that leads from the crater of a volcano down to pools of magma?
A volcanic vent or conduit is an opening that leads from the crater of a volcano down to pools of magma below the surface. This conduit allows magma to travel from the magma chamber to the surface during an 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.
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.
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.
Is magma a explosive eruption and why?
Magma is not an eruption. Magma is a mixture of molten minerals and dissolved gas that is underground. All volcanic eruptions, apart from phreatic eruptions, involve magma.
What type of volcanic eruption depends on the amount of gases and the composition?
The type of volcanic eruption depends on the amount of gases and the composition of magma. In addition to the composition of the magma, the volcanic eruption depends on the ration of sulfur, carbon dioxide, and water the magma contains.
