Does Granite cools very quickly?
No. Granite cools relatively slowly; its large crystals are one method of observing this. Granite is referred to as a "phaneritic" igneous rock, meaning that it is coarse-grained. Coarse-grained rocks cool slowly, which means that the minerals have time to form large crystals before the rock solidifies. A rock with the same composition as granite that does cool quickly is called rhyolite.
What type of rock is hard wearing and and has large crystals?
granite
What minerals does the rock granite always contain?
granite has its composition _ quartz+alkali feldspar
What is one similarity between Granite and Rhyolite?
Both granite and rhyolite are felsic igneous rocks formed from very viscous silica rich magma. They have essentially the same composition. The difference between them is that granite cools slowly underground, forming large crystals while rhyolite cools rapidly above ground after a volcanic eruption forming small crystals or no crystals.
What are two types of igneous rock?
Two types of igneous rock are intrusive (also called plutonic) and extrusive. There is also porphyry rock which is partly intrusive and partly extrusive. Porphyry rock has large crystals embedded in a mass of much smaller crystals. The large crystals formed underground as does intrusive rock, and were carried in lava when it erupted. The mass of smaller crystals formed around the large crystals when the lava cooled quickly above ground, as does extrusive rock.
An extrusive rock with a composition similar to granite but with smaller crystals?
ryholite
What is an extrusive igneous rock with a composition similar to granite but with smaller crystals?
Rhyolite.
What is an igneous rock with crystals?
Granite with larger crystals, basalt with smaller crystals.
What is an example of an intrusive igneous rock with large crystals?
Porphyrite of any composition, granite, gabbro, diorite. Most intrusive igneous rocks have crystals large enough to see with the naked eye. Another term used to define an igneous rock with large crystals is coarse-grained.
Which rock has big crystals?
granite!

What is Granite crystal?
Granite is an igneous rock with visible mineral crystals.
What is an extrusive igneous rock with large crystals?
granite
Is granit a porous rock?
The crystals of granite are very tightly interlocked. This means that granite is not a very porous type of rock.
What is a hard rock made of crystals-not permeable?
granite is a hard rockk madeof crystals
What type of rock is hard wearing and and has large crystals?
granite
What rock has the same composition as granite?
Rhyolite is the extrusive equivalent in chemistry and density of granite.
