If lava cools too fast, whether it is mafic, felsic, or intermediate crystals fail to develop and volcanic glass forms.
they depend on how fast it cools down
When magma cools fast, crystals are small.Less time to form crsytalsWhen magma cools slow, crystals are large.More time to form crystalsWhen magma cools very fast, crystals do not form; nothing.Very less time to formWhen magma cools very slow, large crystals form; a LOT.A lot more time to form

Yes they will
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.

Fast moving-melted lava.
mafic
Its surface area to volume ratio.
Dacite lava flows at speeds orders of magnitude slower than mafic lava.
It will be an igneous rock

The volcano is very wide it means that it has mafic magma. The composite volcanoes have mafic magma in them. When the volcano erupts the lava flows down really fast, but hardens really slowly causing the volcano to widen its width size.
when something is heated the particles are moving very fast and then has it cools down (and heat releases into the air) particles begin to slow down, which means theyre cooling down.
The center of the earth is the hottest, and the crust is the furthest away from that heat.
