WebEarth affects the cooling process and visible properties of igneous rocks. Science Content for the Teacher: Key Ideas 1. A mineral is a solid substance that has a crystalline structure. 2. A crystalline material has a structure that is a regular order (arrangement) of atoms or molecules in a substance. 3. WebA pluton is an igneous intrusive rock body that has cooled in the crust. When magma cools within the Earth, the cooling proceeds slowly. Slow cooling allows time for large crystals to form, so intrusive igneous rocks have visible crystals. Granite is the most common intrusive igneous rock (see figure 2 for an example).

Cooling rate dependence of nucleation and growth rates
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. WebBecause larger grains generally indicate longer cooling rates, the phenocrysts indicate that the magma experienced an initial phase of slow cooling deep underground.
