Which type of magma causes quiet volcanoes?
Mafic magma (low in silica content) typically causes quiet eruptions because it is less viscous and flows more easily, leading to gentle lava flows. These eruptions are characterized by low explosivity and can result in shield volcanoes or lava plateaus.
Which magma contains small amounts of silica and has a low what?
Basaltic magma contains small amounts of silica and has a low viscosity, meaning it is relatively fluid and flows easily.
What type of magma causes quiet eruption?
Magma with low viscosity, such as basaltic magma, typically causes quiet eruptions. This type of magma flows easily and allows gases to escape, resulting in relatively gentle eruptions with less explosive activity.
Is it true how easily magma flows depends on its visocisty?
Yes, the ease of magma flow is influenced by its viscosity. Magma with low viscosity (more fluid-like) flows more easily, while magma with high viscosity (more sticky) tends to flow less easily and may lead to explosive volcanic eruptions. Viscosity is mainly determined by the magma's temperature, composition, and gas content.
What type of magma is produced in the Kilauea?
Kilauea volcano typically produces tholeiitic basalt magma, which is low in silica content and flows easily. This type of magma is associated with shield volcanoes like Kilauea, known for their gentle eruptions and copious lava flows.
Which is characteristic of the magma that formed the Hawaiian islands?
magma that is low in silica and flows easily
What type of magma causes quiet volcanoes?
magma that is low on silica & thin and runny & it flows easily

Which is not a characteristic of magma from an explosive eruption?
flows easily

Magma that is low in silica and produces nonexplosive eruptions is called?
Magma that is low in silica and produces nonexplosive eruptions is called basaltic magma. As basaltic magma has a low viscosity due to its low silica content, it tends to flow more easily, resulting in nonexplosive eruptions with lava flows.
What type of magma does surtsey have?
Surtsey has basaltic magma, which is associated with the eruption of shield volcanoes. This type of magma is characterized by its low silica content and fluidity, allowing it to flow easily to the surface and form lava flows.
Is flows easily a physical property of magma from a explosive eruption?
no
What mineral that affects magma thickness?
The mineral that affects magma thickness is silica. Magma with high silica content tends to be more viscous, resulting in thicker magma. Conversely, magma with low silica content is less viscous and flows more easily.
