Answer:
The intermediate magma has a heterogeneous structure, since it has a part of Silice, approximately 50-60% to be more exact.
When it turns into lava, it produces rocks like the Andesite and, in the opposite case of its crystallization, it forms rocks like the Diorite.
A comparison of felsic magma is much more viscous.
It is important to clarify that this magma is a type of primary magma, that is to say that they are magmas formed from the fusion of the rocks of the mantle or the crust.
Explanation:
The fusion of these rocks are what would give rise to the intermediate magma, this intermediate magma is a primary magma, like the mafic and felsic.
The primary magmas unlike the derived magmas is the origin or the reason for how they are formed, which is what we write above, derived magmas usually form differently since they are the product of the evolution or changes that magmas undergo primary
Answer:
Use of groups of stars called plough to find northern direction by locating the pole star and use of southern cross by using the brightest star which is over south pole to find northern direction
Answer:
Number 2- Misreading the data is a very serious issue
Explanation:
Answer:
Option (C)
Explanation:
San Andreas is a prominent example of a transform fault, in which the plates namely the Pacific Plate and the North American plate slide past each other. The movement of the associated plates in this fault is in the right lateral, strike-slip. With the continuous and rapid movement of both the plates in its respective direction, the west side of the fault would get detached from the fault zone and lead to the formation of an island. The movement of the plates along this fault is responsible for the occurrence of shallow focus tremendous earthquakes.
Thus, the correct answer is option (C).
