I believe the answer is B
The correct answer is - B. Rhyolitic.
The rhyolitic magma has a trademark signature to be the magma type that causes the most catastrophic, powerful, explosive volcanic eruptions. This is due to the composition of the magma. This type of magma is very high in silica content, which in turn makes it very viscous, and because it is very viscous, the high amount of gasses that it contains remain trapped in it, the pressure is building up inside of it, so when it reaches the surface it is highly explosive.
Answer:
d) The lithosphere is broken into sections called plates.
Explanation:
Plate tectonics is the movement of the lithosphere and is responsible for such phenomena as volcanoes and earthquakes. The lithosphere is the exterior layer of the earth about a hundred kilometers thick. This layer is broken into large sized plates, about seven medium plates and numerous smaller plates.
These plates move a couple of inches every year from each other and are the cause of volcanoes and earthquakes.
Remains of Mesosaurus, a freshwater crocodile-like reptile that lived during the early are found solely in Southern Africa and Eastern South America. It would have been physiologically impossible for Mesosaurus to swim between the continents.
Answer:
Migration boosts the working-age population. Migrants arrive with skills and contribute to human capital development of receiving countries. Migrants also contribute to technological progress. Understanding these impacts is important if our societies are to usefully debate the role of migration
