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:
the smallest star right now is the red dwar star which is also called OGLE-TR-122b with a radius of 0.12 solar radii
the largest star is UY Scuti it is roughly 1700 times larger than the sun
Explanation:
Money from tourism and Fertile soil
Our agricultural activities exert an important influence on the soil biota, their activities and diversity Clearing forested or grassland for cultivation drastically affects the soil environment and hence reduces the number and species of soil organisms. The reduction of quantity and quality of plant residues and the number of higher plants species leads to a reduction in the range of habitats and foods for soil organisms.
Answer: 133.1 units ²
Explanation:
First find the area of the Parallelogram;
= Base * height
= 18 * 6
= 108 units²
Area of a semi circle;
= πr²/ 2
r = diameter/2 = 8/2 = 4
= (π * 4²)/2
= 25.1 units²
Area of both = 108 + 25.1
= 133.1 units ²
