How is the size of mineral crystals in igneous rock related to the rate at which they cool?
When igneous rocks cool quickly, they have small crystals and have a texture that may be described as aphanitic. When igneous rocks cool slowly, they have much larger crystals and have a texture that may be described as phaneritic or pegmatitic.
What is a dark fine grained rock called?
They are rocks formed from lava at or near the surface. Basalt is a typical fine-grained extrusive igneous rock, composed of mineral crystals that require magnification to see. The fine-grained texture is due to rapid solidification of the lava which leaves little time for large mineral crystal formation.
Would mica be consider a rock?
Mica is not a type of foliated rock but is in fact the name for a subdivision of a group of minerals known as Phyllosilicates. They form as parallel sheets of silicate tetrahedra resulting in thin sheet like crystals. Foliations are planer alignments of crystals within metamorphic and igneous rocks and foliated rocks may contain micaceous minerals. See the related link for a picture of a Quartz-Mica Schist seen in thin section and viewed through a petrographic microscope with the polarising filters crossed. In the example picture the white, grey and black amorphous blobs are quartz crystals and the long, thin, brightly coloured (predominantly blue and yellow) crystals are muscovite mica.
What rocks are related in the earth system?
all types of rocks, are like related to the earth system. igneous rocks, sedimentary and metamorphic rocks..Igneous rock is like the primary rock or mother rock.
Is diamond from crystal stone?
Diamond is a mineral, commonly found in crystals, and used as a gem.

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.
What does an igneous rock's crystal grain size indicate to the observer?
The size of the mineral crystals in an igneous rock is related to the rate of time spent in cooling from magma. Longer exposure to the crystallization temperature means larger crystals. Less time means smaller crystals, or in the case of obsidian, which cools extremely quickly, no crystallization.

How is the texture of an igneous rock related to the rate which it cooled?
Quick cooling of magma results in small crystal formation. Slow cooling magma results in larger crystals.
What is related words for igneous?
another word for igneous is fire.
Is a igneous rock related to granite?
granite is an igneous rock

How are minerals related to salts?
Halite is a mineral that is directly related to salts. Common table salt is mined and refined from the mineral halite.
Is diamond an igneous or sedimentary rock?
Igneous, it is brought to the surface as an igneous Xenolith. The diamond crystal itself is of metamorphic origin it is metamorphosed carbon. It is more closely related to igneous rocks, as diamond forms in magma under very high temperatures and pressures, where there is no appreciable oxygen to burn the carbon. Artificial diamonds can be "grown" in a similar way by accumulating individual carbon crystals from a hot plasma (gas), in a process called chemical vapor deposition.
How is magma and igneous rocks related?
Magma is molten rock, and igneous rock is cooled magma.
All minerals are made of crystals what does this statement mean?
This means that the material in question (in this case a mineral) is composed of atoms or molecules that are arranged in an orderly pattern in three dimensions. For more information, please see the related link.
