DMPQ: Differentiate between the Composite and the shield Lava.
Composite lava are highly viscous with a high melting point. They are light colored and have low density, and have a high percentage of silica. They flow slowly and seldom travel far before solidifying. The resultant cone is therefore steep sided. The rapid solidifying of lava in the vent obstruct the flow of the out-pouring … Read more DMPQ: Differentiate between the Composite and the shield Lava.
