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

Are metamorphic rocks formed above or below ground?

Metamorphic rocks are formed below ground through the process of metamorphism, where existing rocks are subjected to high temperatures and pressures causing their mineral structure to change. This process typically occurs deep within the Earth's crust.


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 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


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.


What type of rocks can melt into lava or magma?

Igneous rocks, specifically those that are formed from the cooling and solidification of magma, can melt back into lava or magma when subjected to high temperatures and pressure. Additionally, sedimentary rocks can also melt into magma if they are buried deep within the Earth's crust and exposed to extreme heat. Metamorphic rocks, formed under heat and pressure from existing rocks, can similarly melt into magma under sufficient conditions.

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 type of rock is formed when magma undergoes crystallization above ground?

Igneous rocks like rhyolite or andesite are formed when magma undergoes crystallization above ground. These rocks cool relatively quickly, resulting in smaller mineral crystals compared to rocks formed from magma crystallizing deep underground.


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 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.


Which rock is found deep underground?

Igneous rocks such as granite and basalt are commonly found deep underground as they form from the cooling and solidification of magma beneath the Earth's surface. Metamorphic rocks like gneiss and slate can also be found deep underground as they are formed from the alteration of existing rocks under high temperature and pressure conditions.
