Answer:
E. Mineral content
Explanation:
Viscosity is an internal property of a fluid that offers resistance to flow, the nature of volcanic eruptions is highly dependent on magma viscosity and also on dissolved gas content (dissolved gases become trapped by thick magma and the magma chamber begins to build pressure).
The viscosity of magma is controlled by the size of the molecules that comprise it.
<em>Felsic lava contains elements of small size (sodium and aluminum), these elements form polymers and large crystalline macromolecules like silica, the more extensive silicate chain molecules the more viscous the magma becomes, this happens because larger molecules have stronger intermolecular bonds preventing movement and spreading. </em>
Mafic and ultramafic lava, on the other hand, have lower viscosities, also contain lower quantities of silica and aluminum and are rich in magnesium oxide, which does not form large molecular structures, therefore lava flows smoothly, unrestricted by intermolecular forces.

Pristine beaches, compelling history, sprawling rice terraces, and an abundance of activities to suit every type of traveler – Southeast Asia has these things in spades. It's also steeped in rich, ancient customs and traditions that are remarkably different from those of the West
China or India
but I personally believe it is India as it doesn't have a big land but loads of people
Kievan Russia declined in the 12th century because of internal problems and the Mongol invasions. Around 1300, the Orthodox Church chose Moscow as its center. As a result, Moscow, originally a region of Russia, began to emerge as an important city. it is about 1000 mi or 2000 km
The answer is 10%. Hope this helps :)
