What type of texture forms from igneous rock cooling very quickly?

When lava cools quickly, the minerals in it form very tiny crystals which can usually only be seen under a microscope. To the eye, this results in a smooth appearance.

What term describes an igneous rock that forms quickly on earths surface from cooling lava?
Extrusive.
Igneous rock that cools very quickly when it forms may have a texture that is what?
smooth and shiny with no visible grain.
Igneous rock that cools very quickly when it forms may have a texture that is?
Smooth and shiny with no visible grain.
What type of rock forms due to heating and cooling?
igneous rock is formed by heating and cooling.
Why do igneous rocks have either have fined or coarsed grained?
The texture is mostly dependent on the amount of time the magma or lava had to crystallize into a solid rock. Volcanic rock is formed from quickly cooling lava (also called extrusive igneous rock), and will have a fine-grained texture. Plutonic rock (also called intrusive igneous rock) is formed from slow cooling magma, and will exhibit visible crystals.

What characteristics determines the chemical composition of an igneous rock?
An igneous rock is any crystalline or glassy rock that forms from cooling of a magma. Color and texture help determine the chemical composition of the rock.
What type of rock forms due to heating and cooling?
igneous rock is formed by heating and cooling.
What is the type of rock that forms with the cooling of magma?
igneous
Is an igneous rock formed by weathering?
No. Igneous rock forms from the cooling of molten material.
Does sedimentary rock form from the cooling of magma?
No. Igneous rock forms from the cooling of magma.
A fine grained igneous rock forms?
quick cooling
How is the size of crystals in an igneous rock related to the formation of a rock?
If an igneous rock is formed from slowly cooling magma under the ground, it has more time to form crystals and so the crystals it forms are much larger than igneous rock formed from more quickly cooling magma or lava.
