What else can I help you with?
Is thick and sticky a physical property of magma from an explosive eruption?
Yes, magma viscosity (thickness) and stickiness can be physical properties of magma from explosive eruptions. Higher viscosity and stickiness can lead to explosive eruptions because gas bubbles are trapped in the magma, building up pressure until a violent release occurs.
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.
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 is the eruption of magma that comes from ice rather than rocks?
A eruption of magma that comes from ice rather than rocks is called a glaciovolcanic eruption. It occurs when magma interacts with ice or snow, causing explosive eruptions due to the rapid vaporization of water. These eruptions can lead to the formation of volcanic landforms like tuyas and subglacial volcanoes.
What about magma affects how explosive an eruption will be?
The composition of the magma affects how explosive a volcanic eruption will be.
What kind of of volcanic eruption occurs when basaltic magma is present?
Basaltic magma usually produces a Hawaiian or Stombolian style of eruption.
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?

If the water content of magma is high?
an explosive eruption is more likely.
