Igneous rocks are formed by the cooling and hardening of molten material called magma.


What structures form from the cooling and hardening of magma beneath earth's surface?

When magma cools slowly deep underground it produces a rock with larger crystals than when the magma (or lava) cools quickly near (or on) the surface.Rocks with the largest crystal structure are described as 'pegmatitic'.Rocks with crystals visible to the naked eye are described as 'phaneritic'.Rocks with no apparent crystal structure are called 'aphanitic'


How does surface hardening different from true hardening?

in my opinion surface hardening is applied only on the surface while the true hardening is applied in the whole part of the metal....


What exactly is case hardening?

Case hardening, also referred to as surface hardening is the process of hardening a surface of a metal. It is done by surfacing the metal surface with a layer of metal on top of it, in order to harden it.


What is case hardening?

How you can increase melting point of aluminium?

To increase the melting point of aluminium, (and treating this as a philosophical question), then hardening the 'crystal matrix' may be one approach. Surface hardening by work hardening, or perhaps by inserting nitrogen ions into the surface as is used in metal(ferrous) hardening.

What is the surface cooling that results when a substance evaporates?

surface cooling occours when a substance evaporates after taking sufficient heat from the body itself intended to be cooled, creates a sensation of cooling on the body. But in air conditioning the surface cooling, is one of the method of cooling, having different explanation.


Explain how igneous rocks form?

Igneous rocks are one of the 3 main type of rocks, the others being sedimentary and metamorphic rocks. Igneous rocks are formed from the cooling of lava and magma. There are over 700 kinds of igneous rocks, and most are found beneath the surface of the Earth's crust.
