What is a hardened layer of magma called?
A hardened layer of magma is called a lava flow or volcanic rock.
This type of magma is thick moves slowly and does not flow well?
The type of magma you are referring to is called viscous magma. It is rich in silica and other minerals, making it thick and sticky. As a result, it does not flow easily and tends to form domes or plugs when it erupts.
What mineral determines magma viscosity?
A magma's viscosity is directly related to its degree of silica content.
What type of magma is dark in color?
Dark-colored magma is typically basaltic magma, which is rich in iron and magnesium. This type of magma is known for its low viscosity and ability to flow easily, commonly found in volcanic areas such as shield volcanoes.
What three things indicate the thickness of magma?
Silica content: Magma with high silica content tends to be more viscous and therefore thicker. Temperature: Hotter magma is usually less viscous and flows more easily. Gas content: The presence of dissolved gases, such as water vapor and carbon dioxide, can affect the viscosity of magma, making it thicker.
What natural phenomenom occurs when magma breaks through the earth crust?
A lava flow may flow over the surface from a fissure deep enough to reach the magma layer. Or, if under pressure, an eruption from a volcano.
How does magma flow?
out of the toilet
How do magma flow?
Viscously.
What is the Flow of magma through the earths surface called?
I believe the answer you may be looking for is either Lava or a Volcano
Does lava flow to the surface and become a magma?
No. Magma flows to the surface and becomes lava.
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 effect does silica content have on the charactersitics of magma?
The silica can make the magma flow slower and also can make the magma's color lighter.
What does more iron and magnesium make magma?
More iron and magnesium in magma can make it more dense and viscous. This can result in a thicker magma that is less likely to flow easily. It may also affect the melting temperature and can influence the type of volcanic eruptions that occur.
Does cooler magma flow more or less than hotter magma?
when magma is melted at a higher temp. it'll be more runny so cooler magma will be slower than hotter magma
What is the flow of magma called?
lava rivers -Your welcome
What other liquids flow slowly?
lava ' magma
Does cooler magama flow more or less quickly than hotter magma?
Cooler magma flows slower than hotter magma.
