Earth has several ideal features which enable it to support life. Most important is the.
Julli [10]

The elements that make up the earth are the main reason for life on earth. The elements include water as a component of life support; an atmosphere with a composition suitable for life; and the distance between the sun and the earth is neither too close nor too far away and also on earth has oxygen and gravity.

Describe the four processes of magma differentiation.
andrezito [222]

Answer:

the four processes of magma differentiation are starting with Fractional crystallization , Assimilation , Replenishment and Magma mixing.

Explanation:

Magma differentiation -

It is also called igneous differentiation , is a kind of combination term for the various processes involved in the chemical change by which magmas undergoes bulk changes during cooling , emplacement , partial melting process or eruption .

The process involved has been called the FARM process , i.e , starting with Fractional crystallization , Assimilation , Replenishment and Magma mixing.

Fractional crystallization of igneous rocks

This is the most important geochemical process that is working inside the Earth's crust and the mantle . This process of segregation and removal from the melt of the mineral precipitates , that can change the composition of the melt .

The process is complex in context as it varies by a wide variety of phenomena , that are , temperature , composition and the pressure .

Assimilation -

This process explains the mafic magmas as it get rise from the crust and the felsification of the ultramafic . The assumption involved in this process is that the hot primitive melt intrudes into a cooler and the felsic crust will melt crust and get mixed with the resulting melt , which in turns alters the composition of primitive magma .

Replenishment  -

During the process of the cooling of the melt , the results are limited so as to produce a solid body of intrusive rock , which is homogeneous in nature and which has uniform composition and mineralogy . This is due to -

The fresh magma can change the melt's composition ,and the fresh magma can destabilizes the minerals , even change in temperature can lead to rapid crystallization .

Magma mixing  -

The composition in between of two end - member magma is achived by combining two magma's and forming a single composition.

This is a common process in the volcanic magma chambers , that are a open - system chambers , and magma under goes various processs of assimilation , fractional crystallization , and partial melt extraction and are replenished . Even this process is operated deep in the crust and is one of the primary mechanism for the formation of the rocks like monzonite and andesite .

Rate of cooling impact crystal size -

Crystals are formed by the cooling of the magma ,

There are two types of cooling possible , rapid cooling and slow cooling , both can lead to different types of crystal .

If the magma is cooled quickly , i.e. , rapid cooling , the crystals will not have time to form , hence are small in size ,

And in case the magma is cooled slowly , the crystals will have ample amount to time to grow in size , and , hence will form larger crystals .

If the igneous rock has large crystals , then it indicates that the rock was formed deep inside the earth , because deep inside the earth , it is warmer .

These are called intrusive rocks, and have a phaneritic texture .

If the igneous rock has small crystals , then it is formed by rapid cooling , near the Earth's surface .  These are called extrusive rocks and have an aphanitic texture .
