Answer:
A volcano with basaltic magma would probably not erupt, but remain in the magma chamber and cool .
Step-by-step explanation:
There are three main types of magma, according to the silica (SiO2) content - basaltic magma, andesitic magma and rhyolitic magma.
Basaltic magmas, originating from the melting of mantle rocks, contain about 50% silica and a low content of dissolved gases. This type of magma is essentially expelled along rifts and ocean-level hot spots. Their constitution varies, depending on the environmental constraints in which they are generated, such as pressure and temperature. These magmas are characterized by the viscosity - related to density, silica richness, temperature and the amount of fluid they contain - which determines their rate of ascent.
When basaltic magmas accumulate in magmatic chambers, at depths of 10 to 30 km, they solidify and give rise to plutonic rocks such as gabbro. When basaltic magmas rise faster than they cool, they solidify and form volcanic rocks, such as basalts.
