The three classifications of magma are mainly identified using their silica composition. Basaltic magma has the lowest silica content of 45-55% by weight. This makes it the least viscous and least explosive. Andesitic magma has 55-65% , making it more explosive and viscous. Rhyolitic magma has 65-75% silica, and is the most viscous and catastrophic.

Answer:
A. Continental crust is less dense than oceanic crust.
Explanation:
Earth's crust can be divided into two categories, oceanic and continental. More of the surface is covered by oceanic crust, but because ocean crust is thinner than continental crust, the volume of the latter is significantly greater.
Oceanic crust is also denser than continental crust as it is made up of basaltic rock, whereas it's continental counterpart contains a type of less dense rock called felsic.
