(iv) How are extrusive and intrusive rocks
Answers
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.
Explanation:
Intrusive rocks are formed from magma whereas extrusive rocks are formed from lava. Intrusive rocks are formed deep inside the surface of the earth whereas extrusive rocks are formed at the surface of the earth when magma finds a way to eject or pour out of the surface.
