Lava viscosity increases as the silica content of the lava increases

Explanation:

The lava that is rich in the silica contents have a large amount of thickness and thus the more felsic the lava is the more is the silica content. The higher the viscosity the higher the silica contents and the more of the crystallization will take place when the lava cools down and more mafic the lava gets less is its viscosity.
