How full the magma chamber is and the amount of gas that is in the volcano.
What else can I help you with?
How is plate tectonics affecting the world?
When plates get pushed together it creates earthquakes and volcanic eruption's.
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 two principal factors determine the nature or explosive potential of a volcanic eruption?
The two principal factors that can determine the nature or explosiveness of a volcanic eruption is Temperature and Composition in terms of its water content, mineralogy and volatility.
What are the factors affecting eruption?
How full the magma chamber is and the amount of gas that is in the volcano.
What are the two important factors that affect the explosiveness of a volcanic eruption?
Pressure and magma
What direction did the ash cloud travel after the island's eruption?
The ash cloud from the island's eruption traveled eastward, affecting nearby areas with ashfall and volcanic gases.
What word that mean a volcanic explosion?
A volcanic explosion is an eruption.
What is volcanic throat?
it is the upperpart of the volcanic chimney during an eruption it is the upperpart of the volcanic chimney during an eruption
How can a volcanic eruption affect the sun?
A volcanic eruption here on Earth can not affect the Sun. However, a volcanic eruption here on Earth can put particles of ash and some volcanic gases into the atmosphere that affects the transparency of Earth's atmosphere to sunlight. With the ash content the skies near the volcano go dark during the day and with the gases (especially sulfur oxides) the amount of cloud cover increases causing sunlight to be reflected and the air to cool.
What factors determine the force of a volcano eruption?
Factors that determine the force of an eruption are magma viscosity and gas content.
What does the VEI stand for?
The VEI stands for Volcanic Explosivity Index, which is a scale used to measure the explosiveness of volcanic eruptions based on factors like volume of erupted material, height of eruption column, and duration of the eruption.
When magma escapes from the mantle to the sufrface of earth it causes a?
volcanic eruption
