The explosive force of a volcanic eruption depends on the type of magma in the magma chamber. The type of magma depends on its _
____.. a) viscosity, gas content, and silica content. b) viscosity, temperature, and water vapor content. c) gas, silica, and water vapor content. d) gas content, silica content, and pressure
The correct answer among the choices listed above is option A. The explosive force of a volcanic eruption depends on the type of magma in the magma chamber. The type of magma depends on its viscosity, gascontent, and silica content. It is by these three properties that magma is classified.
The correct answer is - a) viscosity, gas content, and silica content.
The classification of the magma depends on its viscosity, gas content, and silica content. This are the three components that define the properties of the magma, as well as its behavior, and the types of rocks that will form from it after it cools off when it comes out of the volcano. The eruption of the volcano is also heavily dependent on the composition of the magma, so the different types of eruptions that can be witnessed at the volcanoes, are all defined by the magma composition.
C- Mariana Trench. It’s the only different form the rest. The others are a consequence of plates subduing or getting under another plate and pushing up.
