What about magma affects how explosive an eruption will be?
The composition of the magma affects how explosive a volcanic eruption will be.
An explosive eruption occurs if magma is?
Eruptions are explosive if the magma is viscous and has a high gas content.
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
Is flows easily a physical property of magma from a explosive eruption?
no
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.
Is magma a explosive eruption and why?
Magma is not an eruption. Magma is a mixture of molten minerals and dissolved gas that is underground. All volcanic eruptions, apart from phreatic eruptions, involve magma.
If the water content of magma is high?
an explosive eruption is more likely.
Is thick and sticky a physical property of magma from an explosive eruption?
Yes.
Does Mt Makushin have sticky magma?
yes it does have sticky lava it is a explosive eruption it has dark sticky magma
What kind of of volcanic eruption occurs when basaltic magma is present?
Basaltic magma usually produces a Hawaiian or Stombolian style of eruption.
