Which type of rock forms when molten material cools and hardens inside Earth?

Igneous rocks are formed when magma (molten rock deep within the earth) cools and hardens. Sometimes the magma cools inside the earth, and other times it erupts onto the surface from volcanoes (in this case, it is called lava). When lava cools very quickly, no crystals form and the rock looks shiny and glasslike.

Accordingly, how is molten rock formed and what type of rock does it create when it hardens?

Magma is molten (melted) rock under the surface of the Earth. When magma reaches the surface it is then called lava and the eruptions of lava and ash produce volcanoes. The lava that reaches the Earth's surface will harden and become igneous rock.

what do we call rocks formed from molten earth material? Answer and Explanation: Igneous rocks are formed from molten material. Igneous rocks can be divided into two main subgroups: intrusive and extrusive. Intrusive igneous rocks

Also know, what is the classification of a rock that is formed by cooling lava?

Extrusive igneous rocks, also known as volcanic rocks, are formed at the crust's surface as a result of the partial melting of rocks within the mantle and crust. Extrusive igneous rocks cool and solidify more quickly than intrusive igneous rocks. They are formed by the cooling of molten magma on the earth's surface.

What rocks are formed from molten material?

There are three basic types of rock: igneous, sedimentary, and metamorphic. Extremely common in the Earth's crust, igneous rocks are volcanic and form from molten material. They include not only lava spewed from volcanoes, but also rocks like granite, which are formed by magma that solidifies far underground.
