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.
Which would you expect to cause the greatest amount of contact metamorphism an intrusion of basaltic magma or an intrusion of rhyolitic magma?
An intrusion of basaltic magma would likely cause greater contact metamorphism compared to an intrusion of rhyolitic magma. Basaltic magma has higher temperatures and higher fluidity, allowing it to heat surrounding rocks more effectively and induce more intense metamorphic changes.
