Is basaltic or andesitic magma hotter?
Basaltic magma is hotter than andesitic magma.
Is basaltic magma or granitic magma hotter?
Baslatic magma is hotter.
When equal amounts of a basaltic and granitic magma mix what is the resulting magma?
basaltic
Does basaltic magma have a lot of silica or very little?
Basaltic magma is low in silica compared to andesitic or granitic magma.
If basalt is in lava is the volcano explosive?
No. The more basalt the quieter the eruption. Basalt is deep deep material, from down where there are few volatiles to make lava explosive.
What is the source of the magma in Hawaii's volcanoes?
Basaltic
Is basaltic or andesitic magma hotter?
Basaltic magma is hotter than andesitic magma.
Is basaltic magma or granitic magma hotter?
Baslatic magma is hotter.
When equal amounts of a basaltic and granitic magma mix what is the resulting magma?
basaltic
Does basaltic magma have a lot of silica or very little?
Basaltic magma is low in silica compared to andesitic or granitic magma.
What color rocks does basaltic magma form?
Basaltic magma usually forms a black rock.
Which would you expect to cause the greatest amount of contact metamorphism an intrusion of basaltic magma or an intrusion of rhyolitic magma?
Basaltic magma
If basalt is in lava is the volcano explosive?
No. The more basalt the quieter the eruption. Basalt is deep deep material, from down where there are few volatiles to make lava explosive.
What is the source of materials for volcanoes that erupt in both ways how do you know?
Crusts must have both granitic (continental) plate and basaltic (oceanic) plate to cause both explosive (granitic magma) and non-explosive (basaltic magma) eruptions
What magma is the most abundant type erupted at oceanic spreading centers?
Basaltic magma.
Are pyroclasts formed by basaltic magma or andesitic magma?
Pyroclasts can be formed of any type of magma. However, they are more likely to form with andesitic than basaltic magma. Rhyolitic magma will also readily form pyroclasts.
What are the characteristics of magma associated with shield volcanoes?
Basaltic, runny magma.
