Which moves fast felsic lava or mafic lava?
A mafic lava flow will move faster than a felsic lava flow due to its lower viscosity. However, felsic magma tends to erupt explosively, producing fast-moving pyroclastic flows instead of lava flows.
What type of lava does an explosive eruption produce?
An explosive eruption typically produces thick and sticky lava known as silica-rich or felsic lava. This type of lava has high viscosity and trapped gas bubbles, causing it to erupt violently. As the lava is very viscous, it can block and build pressure in the volcano, resulting in explosive eruptions.
Where does felsic lava form at?
== == Felsic lava has a higher silica content than mafic lava. Felsic lava is slower moving (high viscosity) than the less viscous mafic lava. Mafic lava is higher in dark minerals and higher in the elements iron and magnesium.
What is moving Lava?
Felsic magma.
Why would felsic lava not produce a natural tunnel within itself as it cools?
Lava tubes formed from mafic lava form when the lava forms a crust over itself, creating a tube through which it can flow and later leave empty. Felsic lava forms a crust, but is too viscous to entirely flow out of it.
Is felsic lava thick?
Felsic lava is a slower moving lava, with high silica content. Most felsic lava deposits as granite, granite, muscovite, and orthoclase.

Between mafic lava and felsic lava which flowsfaster?
Mafic lava is hotter than felsic lava and therefore flows faster.

Where did felsic lava get its name?
The term felsic des derived from feldspar and silica, which are the primary components of felsic rock.
Where is a thick and sticky lava found?
Thick and sticky lava, known as pahoehoe lava, is typically found in Hawaii and other hot spot volcanic regions. Pahoehoe lava has a smooth, rope-like texture due to its high viscosity and low gas content, which causes it to flow slowly and form characteristic swirls and folds as it cools.
What type of magma does Mt.Tambora have?
felsic lava
What kind of lava is in Mt Vesuvius?
the type of lava from mt vesuvius is felsic lava in a pyroclstic explosion.
Does mt etna have mafic or felsic lava?
Oh, dude, Mt. Etna has both mafic and felsic lava. It's like a lava buffet up there! Mafic lava is low in silica and more runny, while felsic lava is high in silica and thicker. So, yeah, Mt. Etna serves up a mix of both, keeping things interesting for all the volcano enthusiasts out there.
