There are almost no extrusive rocks on the earths surface because they are all under the earths surface. They are mainly lower than the earths surface.
Yes and the 20 minerals are called rock forming minerals.
because they are afraid of the light
The Extrusive igneous rock is formed on the earths surface while the Intrusive igneous rock is formed within or inside the earths crust.
The earths crust is a part of the outermost layer.
Silicon is a mixture of the minerals of the earths crust. so.... silicon isn't something from the earths crust. -thanks for your question.
thinner and denser
how wide is the earths crust

Intrusive Rocks are found underneath Earths crust, while Extrusive rocks are found above Earths crust.
Well that will be intrusive igneous rocks, extrusive forms inside the earths crust
The Extrusive igneous rock is formed on the earths surface while the Intrusive igneous rock is formed within or inside the earths crust.
Volcanic (Extrusive) igneous rock, which are formed by lava that comes out of the earths crust, then cools and solidifies rapidly on the earths surface due to exposure to the environmental atmosphere.
sedimentary rock are extrusive when the were formed outside land than in the dirt extrusive rocks take less time to form than intusive (formed under ground) becase wind and help it form faster. i hope this is very helpful =)
If it finds its way dowm into the earths crust through rock cycle and then is melted and mixes together to form molten magma, it could re-erupt to the earths surface and form an extrusive igneous rock or cool and solidify within the earths crust as an intrusive igneous rock.

It would have to be melted into the earths magma and cool down as either intrusive (inside the earth) or extrusive (on the Earth's crust) igneous rock.
