no its the least silica rich of granitic and andesitic magma.
Acidic lava is very viscous, and thus will harden and block the vent. The magma will force its way out through the vent and create a violent explosion.
silica rich magma associated with explosive eruptions because it tends to trap water and gas bubbles :)
High silica magma is light in color, thick, sticky and less dense than basalt magma. The magma that forma volcanoes is rich in silica. High silica magma have low temperatures because magma that is high in silica have the lowest temperatures. Silica rich magma builds a tall cone shaped volcano, a Stratovolcano. Magma that is high in silica resists flowing, so expanding gases are trapped in it. Pressure builds up until the gases blast out in a violent, dangerous explosion.

An acid magma or a granitic magma.
Silica is sand dust.

red or scarlet
Yes
Low silica defines BASALTIC rocks. Iron rich is defined by FERROUS. Not sure about Mg though. Mineral rich is a good one...
The three types of magma, named for the rock they form are basaltic, rhyolitic and andesitic. Rhyolitic magma is rich in silica and water vapor.
yes
