The first statement is about CLIMATE and the second is about WEATHER.
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!
Mining hope my answer helped............
The mongooses are very effective in controlling the snake populations, as is the case in Hawaii, but the problem is that they represent an invasive species. As an invasive species, they disrupt the whole ecosystem on the islands, the local fauna can not cope with them because they do not have the defense mechanisms needed, nor can reproduce as fast, and also head to head are out competed, so the local fauna is becoming endangered and in time will probably get exterminated by the invasive mongooses.
Answer:
(1) Type of lava erupted and its viscosity; (2) Steepness of the ground over which it travels; (3) Whether the lava flows as a broad sheet, through a confined channel, or down a lava tube; and (4) Rate of lava production at the vent.
