Magma is liquified rock under the Earth's crust. When it emerges from a volcano it is renamed lava.

What type of areas are most likely to form metamorphic rocks such as gneiss and schist?
Metamorphic rocks are most likely found at a site that is deep under ground. Metamorphic rocks are formed by other materials under great amounts of pressure. This pressure is caused by plate collisions in the lithosphere.
Why are igneous rock formed?
They can be formed underground or above ground. Underground, they are formed when melted rock, called magma, deep under the earth's surface is trapped in small pockets. As these pockets of magma cool slowly underground, the magma develops into igneous rocks. Igneous rocks are also formed when volcanoes erupt, causing the magma to rise above the earth's crust. When magma appears above the earth, it is called lava. Igneous rocks are formed as the lava cools above ground.
How does metamorphic rock form example?
Phyllite is an example of a metamorphic rock which may have formed from slate, another metamorphic rock.
How do rocks that are formed deep below Earth's crust get to the surface?

How do you classify rocks were they form?
those formed deep into the earth are called Intrusive or Plutonic rocks,those formed ator near thesurface are called Extrusive or volcanic rocks

Why do metamorphic rocks often formed deep under the surface of the earth?
Metamorphic rocks are often found deep under the earth's surface because metamorphic rocks form from heat and pressure. Therefore, they form while they are under the earth's surface.
What are the three formation of minerals?
There are three different kinds of rocks, depending on how they were formed. Igneous rocks formed when melted rock cooled and hardened. Sedimentary rocks formed in layers from bits of older rocks and parts of animals or plants. These collect in low areas or under water and harden into rocks. Metamorphic rocks formed when either sedimentary, igneous, or earlier formed metamorphic rocks were put under pressure and heat deep in the earth's crust.
Does exposure to air help metamorphic rocks form?
No metamorphic rocks are formed deep in the crust under great temperature and pressure. No air is down there.
What is formed when rocks deep underground?
Magma

When is igneous rock formed?
Igneous rocks are called fire rocks and are formed either underground or above ground. Underground, they are formed when the melted rock, called magma, deep within the earth becomes trapped in small pockets. As these pockets of magma cool slowly underground, the magma becomes igneous rocks.Igneous rocks are also formed when volcanoes erupt, causing the magma to rise above the earth's surface. When magma appears above the earth, it is called lava. Igneous rocks are formed as the lava cools above ground.
What rock is formed when rocks melt deep underground?
Magma
What type of rock is formed by magma that cools deep below earths crust?
Igneous rocks are formed from cooled magma of lava, sedimentary rocks by sediment under pressure, and mettamorphic from any rock that undergoes much heat and/or pressure.
Where is the igneous rock form?
Igneous rocks are called fire rocks and are formed either underground or above ground. Underground, they are formed when the melted rock, called magma, deep within the earth becomes trapped in small pockets. As these pockets of magma cool slowly underground, the magma becomes igneous rocks. Igneous rocks are also formed when volcanoes erupt, causing the magma to rise above the earth's surface. When magma appears above the earth, it is called lava. Igneous rocks are formed as the lava cools above ground
What do igneous rock form?
Igneous rocks [fire rocks] are formed either underground or above ground. Underground they are formed when the melted rock [called magma] deep within the earth becomes trapped in small pockets, and as these pockets of magma cool slowly underground the magma becomes igneous rocks. Igneous rocks are also formed when volcanoes erupt causing the magma to rise above the earth's surface. When magma appears above the earth, it is called lava. Igneous rocks are formed as the lava cools above ground. Examples of igneous rocks are granite, scoria, pumice, obsidian and basalt.
