The answe is: D. All of the above
Answer:
a. granite, andesite, basalt
Explanation:
There are three basic different types of magma: rhyolithic, andesitic, and basaltic. These three types of magma have different properties which differs them from one another, and which cause different types of eruptions. The rhyolithic (granite) magma has very high viscosity. This magma is the thickest, managing to trap gases in it, and because of it it causes highly explosive eruptions. The andesitic magma is moderate in viscosity, and it has explosive eruptions, but also has lava flows that are relatively slow, so it is very unpredictable what kind of an eruption will the volcano have. The basaltic magma is the least viscous. This means that the eruptions of these volcanoes are not explosive, but instead they produce thin lava flows that cover the surrounding area.
The lower mantle is composed of magnesium, iron-bearing silicates, olvine, and pyroxene.
I have no idea because i’m just tryna use this app and i have to answer a question lol
