The cooling and hardening of magma deep underground results in igneous rock. Rare gems and diamonds can be found in igneous rock.
The cooling and hardening of magma underground results in igneous rock. This rock occurs during extreme heat and is very hard.
That would be a coarse-grained, intrusive igneous rock.
Metamorphic rock .
They are called intrusive igneous rocks.

Igneous
Plutonic
When magma comes in contact with underground water, it creates hot springs, or geysers.
Lava will cool quickly compared to underground magma.
A coarse grained texture, referred to as a phaneritic texture, will be the resultant igneous rock texture. The slower the magma cools the more time minerals have to crystallize and thus grow bigger.
contact metamorphism
Several minerals form in slow cooling magma. Some of those minerals are quartz, plagioclase feldspar, and potassium feldspar. These are the same minerals that are found in granite.
Generally, the volcano is not the result of cooling and hardening deep underground. It is the molten magma in the core of the earth that, when it rises and breaks through the earth's crust, results in volcanic action.
Intrusive igneous rock.
Magma is molten rock. It becomes rock by cooling and hardening.
Diorite is formed by the cooling of intermediate magmas underground.
Plutons
Harding of rock formations through magma flow.
A pluton is a body of rock formed from the cooling of magma under the surface.
The cooling, solidification, crystallization and hardening of molten magma or lava.
Igneous rocks are formed by the cooling and hardening of molten material called magma.
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'
Quick cooling of magma results in small crystal formation. Slow cooling magma results in larger crystals.
It is false. Granite is a igneous rock that was formed from magma cooling and hardening.
