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.
Answer:
249.6 sq. in.
Explanation:
In this question, we need to find the surface area of the triangular pyramid in order to calculate how many square inches are needed to cover it. The formula for the surface area of a triangular pyramid is the following
(a × b) + 
(b × s)
We can say that the values provided represent the following variables.
a = 12in
b = 10.4in
s = 12in
(12 × 10.4) + (10.4 × 12)
(124.8) + (124.8)
62.4 + 187.2
249.6 sq. in.
Finally, we can say that it would take 249.6 sq. in. in order to cover the triangular pyramid.
The answer is either B or D. Letter A doesn't make sense and letter C isn't right either because you need rainfall to have fertile plains.
