<span>vegetable oils are unsaturated so it would create a more liquid soap, while animal fats are saturated so it creates a more solid soap</span>
<span>I think the correct answer is that they can determine the viscosity of the magma. The viscosity of a magma is largely controlled by the temperature, composition and the gas content. Also, silica content can define a magma type. It is said that higher silica content magma has a higher viscosity than those with lower silica content.</span>
I think it’s either B or D
The answer I believe would be A
