Igneous rocks are formed by the crystallisation of a magma. The difference between granites and basalts is in silica content and their rates of cooling. A basalt is about 53% sio2, whereas granite is 73%. Intrusive, slowly cooled inside the crust.
How Is Granite Different from Basalt?
Granite and basalt are two types of rock that are very common in the earth’s crust. They are both igneous rocks, which means that they were formed from the cooling of molten rock material. While they may look similar at first glance, there are several differences between the two that can help you distinguish one from the other.
The first difference between granite and basalt is their composition. Granite is made up of quartz, feldspar, and mica. These minerals give granite its characteristic speckled pattern. Basalt, on the other hand, is made up of mostly plagioclase and pyroxene. These minerals give basalt its dark, fine-grained appearance.
The second difference between granite and basalt is their hardness. Granite is much harder than basalt. This is because of the quartz, feldspar, and mica that make up granite. These minerals are much harder than the plagioclase and pyroxene that make up basalt. As a result, granite is less susceptible to weathering and erosion than basalt.
The third difference between granite and basalt is the way they form. Granite is an intrusive igneous rock, which means that
