Glassy igneous rocks cool the fastest.

Is granite an igneous rock cooled fast or slow.

Granite and pegmatite are examples of rocks that cooled slowly and have large crystals. An igneous rock that cooled quickly is basalt while a slow cooler is granite. The slow cooling at depth allows large crystals to grow. It forms from the slow crystallization of magma below earth s surface.

An intrusive igneous rock is a coarse grained rock which forms as a result of the slow cooling. These are called intrusive or plutonic igneous rocks. 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.

Granite the rock is formed as magma slowly cools and crystallizes solidifies over great lengths of time deep underground. 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. Some cool slowly deep under the earth s surface. Igneous rock the granite has cooled slowly from magma and the rhyolite lava extrusive igneous rock has cooled very quickly.

Igneous rocks can be. Extrusive igneous rock cools outside of. That is why they do not look all the same. The extrusive rock has cooled.

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. The slow cooling formed rocks with large crystals. If magma or lava cools quickly the resulting igneous rock will have. 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.

Which igneous rock cools the fastest glassy aphanitc pegmatic and porphyritic. The result is that visible crystals form as the minerals have plenty. All igneous rocks do not cool the same way.
