What else can I help you with?
Do minerals crystalize out of magma when it melts?
No. Magma is already at least partially molten. Mineral crystallize when magma solidifies.
What has to happen to magma for glass to form?
The magma has to crystalize...
Is basaltic magma or granitic magma hotter?
Baslatic magma is hotter.
Is basaltic or andesitic magma hotter?
Basaltic magma is hotter than andesitic magma. Basaltic magma typically has temperatures ranging from 1000°C to 1200°C, while andesitic magma has temperatures around 800°C to 1000°C.
When equal amounts of a basaltic and granitic magma mix what is the resulting magma?
basaltic
Can minerals crystallize out of magma when it melts?
Yes, minerals can crystalize when magma melts.
What list places the magma What list places the magma types in order of decreasing?
basaltic,andesitic,rhyolitic
What color rocks does basaltic magma form?
Basaltic magma usually forms a black rock.
Does basaltic magma have a lot of silica or very little?
Basaltic magma is low in silica compared to andesitic or granitic magma.
What are the three main types of magma and what factor determines these classifications?
The three main types of magma are basaltic magma, andesitic magma, and rhyolitic magma. They are classified according to their mineral composition. Basaltic magma is composed of SiO2 45-55 wt%, high in Fe, Mg, Ca, low in K, Na. Andesitic magma is composed of SiO2 55-65 wt%, intermediate. in Fe, Mg, Ca, Na, K. Rhyolitic magma is composed of SiO2 65-75%, low in Fe, Mg, Ca, high in K, Na.

What is the process in which previously formed minerals in a basaltic magma are separated from the magma by density is called?
The process in which previously formed minerals in basaltic magma are separated from the magma due to differences in density is called fractional crystallization. As the magma cools, minerals crystallize at different temperatures and densities, causing denser minerals to sink to the bottom of the magma chamber. This separation can lead to the formation of different rock types and mineral compositions in the resulting igneous rocks.
