Is Granite An Igneous Rock Cooled Fast Or Slow

The extrusive rock has cooled.

Is granite an igneous rock cooled fast or slow.

Igneous rocks can be. An example of intrusive igneous rock is granite. Which igneous rock cools the fastest glassy aphanitc pegmatic and porphyritic. Glassy looks like a glass and has no crystals grains rocks cooled very fast.

Some cool slowly deep under the earth s surface. That is why they do not look all the same. Glassy igneous rocks cool the fastest. Granite is a light colored igneous rock with grains large enough to be visible with the unaided eye.

Coarse grained granite is most similar in mineral composition to fine grained. If magma or lava cools quickly the resulting igneous rock will have. An intrusive igneous rock is a coarse grained rock which forms as a result of the slow cooling. Granite and pegmatite are examples of rocks that cooled slowly and have large crystals.

The slow cooling at depth allows large crystals to grow. The result is that visible crystals form as the minerals have plenty. Granite is composed mainly of quartz and feldspar with minor amounts of mica amphiboles and other minerals this mineral composition usually gives granite a red pink gray or white color with dark mineral. Igneous rock the granite has cooled slowly from magma and the rhyolite lava extrusive igneous rock has cooled very quickly.

All igneous rocks do not cool the same way. The slow cooling formed rocks with large crystals. Extrusive igneous rock cools outside of. This leads to a fuller explanation of the terms intrusive and extrusive the intrusive rock has cooled slowly at depth where the overlying rocks have had an insulating effect.

An igneous rock that cooled quickly is basalt while a slow cooler is granite. Granite the rock is formed as magma slowly cools and crystallizes solidifies over great lengths of time deep underground. It forms from the slow crystallization of magma below earth s surface.
