What are the three main types of magma 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.
How are continental rift magma and continental arc magmas different?
Continental rift magmas typically form in regions where tectonic plates are pulling apart, leading to decompression melting of the mantle, which often results in basaltic to andesitic compositions. In contrast, continental arc magmas are generated at convergent plate boundaries where an oceanic plate subducts beneath a continental plate, leading to the melting of both the subducted slab and the overlying mantle wedge, producing more silicic and diverse magma compositions, including andesite and rhyolite. Thus, the primary difference lies in their tectonic settings and resulting mineral compositions.
How many types of magma are there?
their are many types of magma because when a volcano has soft magma that means it either exploded small or the magma was going really slow and fast magma and big exploding volcano's are hard magma.:)

Why are granite igneos rocks lighter in color than basaltic rocks?
Granite igneous rocks are lighter in color than basaltic rocks primarily due to their mineral composition. Granite is rich in light-colored minerals such as quartz and feldspar, which contribute to its lighter hues. In contrast, basaltic rocks contain a higher proportion of dark-colored minerals like pyroxene and olivine, resulting in their darker appearance. This difference in mineralogy reflects the varying magma compositions from which these rocks are formed.
What is igneous that have mineral composistions between those grantic and basaltic rocks?
andesitic rock
What igneous rocks have a mineral composition between that of granitic and basaltic rocks?
Andesite and diorite are two common igneous rocks that have a mineral composition intermediate between granitic and basaltic rocks. Andesite is fine-grained and contains plagioclase feldspar and pyroxene minerals, while diorite is coarse-grained and composed of plagioclase feldspar, amphibole, and other minerals.
What are the three kinds of the earth igeans?
The three kinds of Earth Igneous Rocks are: basaltic (mafic), granitic (felsic), and intermediate (andesitic). These rock types vary in their mineral composition, color, density, and overall characteristics based on the amount of silica and other elements present. Each type forms from different magma compositions and processes within the Earth's crust.

What is the first mineral to crystalize out of a hot basaltic magma?
Olivine
What are the three families of igneous rocks?
The three families of igneous rocks are basaltic (mafic), andesitic (intermediate), and granitic (felsic). These families are classified based on their silica content and mineral composition, which in turn influence their color, density, and overall characteristics.
What is the mineral composition of an intermediate igneous rock?
felsic and something else i do not remember the second one.

What are the mineral compositions of granite?
Granite has feldspar, quartz, biotite.
