Question

7.
Which list places the magma types in order of decreasing viscosity?


andesitic, basaltic, rhyolitic


basaltic, rhyolitic, andesitic


rhyolitic, andesitic, basaltic


basaltic, andesitic, rhyolitic

Answer 1

The correct order of magma types in order of decreasing viscosity is:

**rhyolitic, andesitic, basaltic**

Rhyolitic magma is the most viscous due to its high silica content, followed by andesitic magma, and basaltic magma is the least viscous.
