Answer: c. represent the mafic materials present in the magma

Explanation:

Fractional crystallization is a rock formation process whereby early forming crystals settle at the bottom of the magma chamber and the magma at the top loses its mineral components thereby becoming more felsic in the process.

 

The components of the magma determine how much reaction can occur as silica is important to catalyzing these reactions. The crystals formed at the beginning of these series of reactions represent the mafic materials in the magma but are more mafic that the magma .

Conclusion. The plight of refugees. How you feel the refugees should be treated
Zielflug [23.3K]
The plight of refugees is that they suffer deep emotional stresses from displacement. Fleeing their lives in search of a safer place for them to have a future brings with it poverty, fear and health issues. Upon arrival in a new country, I think that they should be treated with equality, dignity and be given the resources and tools from our society to enable them to build a new life for themselves. After their suffering and journey to seek a better place and better life, societies should embrace these people, their skills and abilities and allow them to be a part of other cultures.

How do volcanoes form?
harina [27]
Volcanoes are formed when magma from within the Earth's upper mantle works its way to the surface. At the surface, it erupts to form lava flows and ash deposits. Over time as the volcano continues to erupt, it will get bigger and bigger.
