For a rock to be classified as an igneous rock it must have been formed by a volcano. So, it could be made out of cooled magma or lava. The different types of igneous rocks are due to different cooling processes. It could have been spewed into the air and cooled on the way down, it could have been underwater and cooled immediately, or it could have oozed out of some crack and cooled slowly. Another way it may have solidified is by a decrease in pressure. For example, being spewed into the air and falling a couple hundred feet.

For metamorphic rock to become igneous rock what steps are necessary?

Metamorphic rock can not become igneous rock, however igneous rock can become metamorphic. This process happens over time as the rocks are shifted, compressed and heated by the Earth.


Which process changes igneous rock into igneous rock?

Melting and crystallization.


What happens to magma when it produces igneous rocks?

The transition form magma to rock is a process of cooling.


What part of the rock cycle happens after the igneous rock?

sedimentary rock


What happens to igneous rock in intense heat and pressure?

In intense heat and pressure, igneous rock can undergo metamorphism, transforming into metamorphic rock. This process involves recrystallization of minerals, and the rock may develop foliation or banding patterns. The original texture and mineral composition of the rock can change as a result of this process.


Which process changes sedimentary rock into igneous?

The process that changes sedimentary rock into igneous rock is called "melting." When sedimentary rock is subjected to high temperatures and pressures deep within the Earth's crust, it can melt and re-crystallize into igneous rock. This process occurs in the presence of magma and can lead to the formation of new igneous rock.


What happens when metamorphic rock becomes igneous rock?

Metamorphic rock continues to heat and eventually melts and becomes igneous rocks.


What is it called When melted rock becomes solid?

When melted rock solidifies, it forms an igneous rock. This process is known as crystallization.


What is the process sedimentary to igneous?

In order to get an igneous rock from a sedimentary rock, the sedimentary rock must be melted and then that melt must crystallize.


What processes must occur to change any rock to igneous rock?

The process that must occur to change any rock to igneous rock is melting.


What happens to magma as it cools?

It forms igneous rock.
