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.
I hope you find this information useful and interesting! Good luck!

Answer:
Coriolis effect
Explanation:
The Coriolis effect is originated from the force that is generated due to the rotation of the earth. This is commonly known as the Coriolis force. This force is responsible for the formation of clockwise and anticlockwise wind patterns in the northern and the southern hemisphere respectively.
There are various convection cells that are formed in different regions on earth. As the wind blows from a region of high pressure to a region of low pressure, on a large scale, and at the same time, the earth also is rotating, so its path gets curved or bends, due to the effect of Coriolis force.
Thus, the apparent bending of the wind while blowing from one place to another is called the Coriolis effect.
The answer is A. Sorry if i'm wrong.
