Fine-grained igneous rock that is formed when molten rock cools quickly and soildfies on Earths surface?
extrusive igneous rock
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.
How and where are igneous rocks formed?
Igneous rocks are formed on and below the surface of the Earth when lava or magma cools enough to crystallize.
What igneous rock are formed when lava cools at earth's surface?
Extrusive igneous rocks are formed
Igneous rocks that form when magma cools on Earths's surface are called what igneous rocks?
Extrusive igneous rocks.
What rock is formed when magma cools slowly beneath earths surface?
Intrusive igneous rock.

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.
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

Igneous rocks that form when magma cools on Earths's surface are called what igneous rocks?
Extrusive igneous rocks.
Are igneous rocks formed only beneath earth's surface?
No. Intrusive igneous rocks are formed beneath the earth's surface when magma cools and extrusive igneous rocks form when lava extrudes from a volcano and cools.
What kind of igneous rock forms when lava cools at earths surface?
Such rock is extrusive igneous rock.
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.
When melted rock cools and hardens an intrusive igneous rock is formed?
when it cools undera lot of pressure underground it is an intrusive igneous. If it cools on the surface of the earth then it is an extrusive igneous.
