Is granite an igneous rock cooled fast or slow.

Glassy igneous rocks cool the fastest. These are called intrusive or plutonic igneous rocks. 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.

Which igneous rock cools the fastest glassy aphanitc pegmatic and porphyritic. If magma or lava cools quickly the resulting igneous rock will have. Extrusive igneous rock cools outside of. Igneous rocks can be.

Coarse grained granite is most similar in mineral composition to fine grained. Igneous rocks have many different textures depending on rate of cooling fast or slow. An intrusive igneous rock is a coarse grained rock which forms as a result of the slow cooling. The slow cooling at depth allows large crystals to grow.

Some cool slowly deep under the earth s surface. Glassy looks like a glass and has no crystals grains rocks cooled very fast. Granite is a light colored igneous rock with grains large enough to be visible with the unaided eye. That is why they do not look all the same.

The link that the students should be encouraged to make is that the intrusive igneous rock the granite has cooled slowly from magma and the rhyolite lava extrusive igneous rock has cooled very quickly. It forms from the slow crystallization of magma below earth s surface. 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. The extrusive rock has cooled.

Igneous rock the granite has cooled slowly from magma and the rhyolite lava extrusive igneous rock has cooled very quickly. Granite and pegmatite are examples of rocks that cooled slowly and have large crystals. An example of intrusive igneous rock is granite.
