What are the two factors that affect the explosiveness of a a volcanic eruption?

The explosiveness of a volcanic eruption is largely influenced by the magma's composition and the amount of trapped gases within it. Magma with high viscosity and gas content tends to lead to more explosive eruptions, as the gases can build up pressure within the magma chamber until they are forcefully released.


What two factors control the explosiveness of an eruption?

The explosiveness of an eruption is primarily controlled by the viscosity of the magma and the amount of gas trapped in it. Low viscosity magma with high gas content tends to lead to more explosive eruptions, while high viscosity magma with lower gas content leads to less explosive eruptions.


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 two factors the control whether a volcano eruption will be explosive or quiet?

The two main factors that control whether a volcano eruption will be explosive or quiet are the viscosity of the magma and the presence of dissolved gases. High viscosity magma (thick and sticky) and high gas content tend to result in explosive eruptions, whereas low viscosity magma (thin and runny) and low gas content lead to quiet eruptions.


What are two factors scientists monitor that could indicate a volcano night erupt?

What are two factors that can affect the distance that volcanic ash can travel?

Wind direction and speed: Strong winds can carry volcanic ash over long distances, while variable wind patterns can influence the direction in which the ash travels. Eruption intensity: The height and explosiveness of the volcanic eruption can determine how high into the atmosphere the ash plume reaches, affecting how far it can be dispersed.

What is the rules of factoring?

Each organism has two factors that control each of its traits. We now know that these factors are genes and that they are located on chromosomes


What determines the strength of a volcanic eruption?

The explosiveness of a volcano is determined by two factors. The obstacles in the magma's path and the type of volcano. When there is chunks of rock and hardened magma in the vent the liquid magma builds up until it sprays out at hufe ferocity. If there is little or no debris then the magma simply spews out. As for the type of volcano when the tectonic plates move apart it forms a row of GENTLE volcanoes but when they crash together the volcanoes are much more explosive.
