The more mafic mineral, the more fluent the magma. In other words, basalt-rich magma is more flowing and felsic-rich magma is more viscous. So, the mafic composition increase the flow of magma. Example: balsalt-islands of Hawaii, very flowing, spreads readily. St. Elens Montain rich in andesite, which is a less mafic rock, is more viscous;thus, more explosive.
Yes. Viscosity is the resistance of a fluid to flowing. A high viscosity means low flowing (I specifically mention this because this is a huge pitfall) When silica content increases, and when temperature decreases, the viscosity of a magma increases along with it.
No. Magma flows to the surface and becomes lava.
Rheology is the term used to describe the characteristics of magma flow, which includes its viscosity, temperature, pressure, and composition. These factors influence how magma moves and behaves beneath the Earth's surface.

The term for the flow of magma through cracks in the Earth's surface is called volcanic eruption. During an eruption, magma is forced through fissures or vents onto the surface, leading to the formation of volcanic features like lava flows, ash clouds, and pyroclastic flows.

Viscously.
it is normally intermediate flow because of the silica content.
Magma always flows.

The silica can make the magma flow slower and also can make the magma's color lighter.
when magma is melted at a higher temp. it'll be more runny so cooler magma will be slower than hotter magma
Cooler magma flows slower than hotter magma.
lava rivers -Your welcome
lava ' magma
It affects the rate of flow of the lava. Hotter means faster flow
