What are extrusive and intrusive igneous rock?
Extrusive rocks are formed outside of earths surface. Intrusive rocks are formed inside earths surface.
If magma crystallizes before it reaches Earths surface will it form an igneous rock?
Yes, if magma crystallizes below Earth's surface it will form igneous rocks like granite or diorite. These rocks are known as intrusive igneous rocks, as they formed from magma that cooled and solidified within the Earth's crust.
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.
How and where are igneous rocks formed?
Igneous rocks are formed when molten magma cools and solidifies either beneath the Earth's surface (intrusive) or on the surface (extrusive). Intrusive igneous rocks are formed from magma that cools slowly underground, while extrusive igneous rocks are formed from lava that cools quickly on the surface.
What groups of rocks can igneous rocks be formed from?
igneous rocks are formed by magma reaching earths surface and cooling quickly to form extrusive igneous rock.another igneous rock is called intrusive igneous rock. it is formed when magma cools and hardens below the surface.
What igneous rocks formed or on or near earths surface?
Volcanoes.
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.
Mountains formed by magma that reaches the Earths surface are?
Mountains formed by magma that reaches the Earth's surface are called volcanoes.
What is the name of the igneous rock that is formed under earths surface?
obsidian is one of them
What are extrusive and intrusive igneous rock?
Extrusive rocks are formed outside of earths surface. Intrusive rocks are formed inside earths surface.
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.
Igneous rocks formed on or near Earth's surface?
extrusive because it forms on or near earths surface
What would have larger crystals igneous rock that formed below earths surface or above?
below
What rock is formed when magma cools slowly beneath earths surface?
Intrusive igneous rock.

The ways Which extrusive and intrusive igneous rocks are formed?
extrusive- when melted rock material coools on earths surface instursive-when the melt cools below earths surface
