Granite has what type of cooling rate
WebBecause larger grains generally indicate longer cooling rates, the phenocrysts indicate that the magma experienced an initial phase of slow cooling deep underground. In rocks … WebWhich type igneous material cools fastest? The difference between an Extrusive and Intrusive igneous rock is the way in which they cool. The inside of the Earth is very hot – hot enough to melt rocks. Lava cools fastest at the earth’s surface. , while magma, which cools more slowly, can form larger mineral crystals.
