An explosive eruption occurs if magma is?
Eruptions are explosive if the magma is viscous and has a high gas content.
How the composition of magma determines an eruption's characteristics?
Silica(te) rich magma is usually an explosive eruption. The explosiveness of an eruption depends on - a) Gases trapped within the magma at eruption b) The Silica content c) The fragility of the crater walls and/or the volcanic plug.
What are some physical properties of magma from an explosive eruption?
Magma is a liquid form of rock beneath the surface of the planet. It has two properties, physical and chemical, you can notice if it is not the physical property of magma if it has the chemical properties of whatever it contains.
Why is mauna loa nonexplosive?
The explosive force of a volcanic eruption comes from gas trapped in the magma. The magma that feeds Mauna Loa has a low gas content.
What type of gas causes a volcano to erupt?
Gasses do not necessarily cause a volcanic eruption, but they often countribute. Water vapor is generally the most significant gas, but others such as cabon dioxide and sulfur dioxide are also present.
An explosive eruption occurs if magma is?
Eruptions are explosive if the magma is viscous and has a high gas content.
If the water content of magma is high?
an explosive eruption is more likely.
What about magma affects how explosive an eruption will be?
The composition of the magma affects how explosive a volcanic eruption will be.
What is the relationship between the silica contents of magma and the explosiveness of a volcanic eruption?
The high the silica content, the explosive and the eruption.

What effect does silica content have on the magma?
Silica content makes the magma thicker which can cause a more explosive eruption, and also make it so more gases aer open to be trapped

How do differences in magma affect volcanic eruptions?
If the magma has a high water content, then the volcano will most likely have an explosive eruption. Also, vocanoes can have explosive eruptions if the magma contains a large percentage of silica. Hope this helps!
What happen if there is a lot of water present in the magma?
Magma with high water content is more likely to cause an explosive eruption because magma is underground, which means it's under intense pressure, and the water stays dissolved in the magma. When magma quickly rises to the surface, the pressure decreases and other compounds, such as Carbon Dioxide (CO), become gases. As gases expand rapidly an explosion can happen.
How can the composition of magma affect the way volcano erupts?
If the composition of the magma is high in silica, the eruption will be explosive. The Eruption of Mt. St. Helens was an explosive eruption. If the composition of the magma is low in silica, it will produce a quiet eruption. The eruption(s) of Mt. Kilauea are quiet eruptions.
