Answer:
The correct answer is Earth’s interior.
Explanation:
The process of formation of igneous rocks begins inside the Earth. Where is the <u>hot liquid magma</u>. When this magma cools it is when igneous rocks are generated.
Two situations can occur: that the <u>magma is slowly cooling inside the Earth</u>, where it will solidify and create <u>intrusive rocks.</u> Or it may happen that hot magma comes out through a volcanic eruption, where it is directed towards the surface through the ducts that are part of a volcano, and <u>once it meets the cold air on the Earth's surface , solidifies and creates volcanic or extrusive rocks,</u> which have very valuable minerals and crystals.
This type of rock is what makes up 95% of the earth's surface.
