Question

2 How is granite different from pumice?
​

Answer 1

Answer:

Granite is an igneous rock that is composed of four minerals. These minerals are quartz, feldspar, mica, and usually hornblende. Granite forms as magma cools far under the earth's surface. Because it hardens deep underground it cools very slowly. This allows crystals of the four minerals to grow large enough to be easily seen by the naked eye. Look at the photo of granite above, notice the different crystals in the rock.

Answer 2

Answer:

granite is usually flat because all of the air bubbles were pushed out of the lava while it cooled. pumice was formed by lava quickly cooling on the surface. pumice looks different because granite is formed on the surface and pumice is formed below the surface.
