Question

How are igneous rocks formed?​

Answer 1

Answer:

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 quicker than intrusive igneous rocks. They are formed by the cooling of molten magma on the earth's surface.

Answer 2

Answer:

Hey mate here's your answer.

Igneous rocks are formed by the solidification of lava. Lava cools rapidly and solidifies on the surface of the earth. Crystals are formed due to the cooling of lava. These rocks can be intrusive as well as extrusive.
