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.
What else can I help you with?
Where do fine grained igneous rock form?
Well that will be intrusive igneous rocks, extrusive forms inside the earths crust
Is sandstone extrusive?
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 =)
Igneous rocks are formed when magma does what?
The Igneous rock formed when magma cools are; 1. Extrusive (Volcanic) Igneous Rock; which are igneous rocks formed when magma cools outside the earths crust. The texture of of extrusive igneous rock is fine grained. 2. Intrusive (Plutonic) Igneous Rock; these are igneous rocks formed by gradual cooling of magma within the earths crust. The texture is coarse grained.
Why are there almost no extrusive ultabaic rocks in Earth's crust?
Extrusive ultramafic rocks are rare in Earth's crust primarily due to their high melting temperatures and the specific conditions required for their formation. These rocks, which are rich in magnesium and iron, typically form deep within the mantle where pressure and temperature are extreme. When they do erupt, they often mix with other materials or undergo crystallization processes that can alter their composition before they reach the surface. Consequently, most ultramafic material remains in the mantle rather than forming extrusive rocks on the crust.
What causes the earths crust to rise and fall?
The sudden vibration in the plates inside the crust causes the earths crust to rise & fall.
Why are there almost no extrusive ultra-basic rocks in earths crust?
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.
How are intrusive and extrusive rock different?
Intrusive Rocks are found underneath Earths crust, while Extrusive rocks are found above Earths crust.
Where do fine grained igneous rock form?
Well that will be intrusive igneous rocks, extrusive forms inside the earths crust
Basic material of the Earth's crust?
The basic materials of the earths crust are; silicate rocks, primary granite, igneous, metamorphic, and sedimentary rocks.
What igneous rock formed from lava have a fine?
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.
How does a metamorphic rock turn into a igneous rock?
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.

What are the parts of earths interior?
There three basic part of earth are The crust The mantle The core
Where is each type of igneous rock formed?
The Extrusive igneous rock is formed on the earths surface while the Intrusive igneous rock is formed within or inside the earths crust.

How might gneiss change into an 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.
