An explosive eruption occurs if magma is?
An explosive eruption occurs if magma is high in gas content and viscosity. The high gas content creates pressure within the magma chamber, leading to a violent release of energy when the eruption occurs. The high viscosity of the magma makes it more difficult for gases to escape, further increasing the explosiveness of the eruption.
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.
How does magma composition and the resulting eruption affect the form of a volcano?
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.
What factors determine the force of a volcano eruption?
Factors that determine the force of an eruption are magma viscosity and gas content.
What factors determine how explosive the eruption of a volcano will be?
In a volcano, the higher the pressure rises before eruption takes place, the more explosive the eruption will be. Some volcanoes seem to be "gentle flow" as a matter of course (like Mauna Loa in Hawaii). Some seem to be explosive as a matter of course (like Vesuvius in Italy). Others manifest both types of eruptions.
What about magma affects how explosive an eruption will be?
The composition of the magma affects how explosive a volcanic eruption will be.
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.
Which is not a characteristic of magma from an explosive eruption?
flows easily

Is the flow easily a physical property of magma from an explosive eruption?
no

If the water content of magma is high?
an explosive eruption is more likely.
What kind of of volcanic eruption occurs when basaltic magma is present?
Basaltic magma usually produces a Hawaiian or Stombolian style of eruption.
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.
How does magma composition and the resulting eruption affect the form of a volcano?

Does water vapor affect how explosive a volcano is?
Yes. More gas trapped in magma leads to a more explosive eruption. Water vapor is the most abundant gas in magma.
