Why are some volcanoes explosive while others are not?
umka21 [38]

There are actually very few volcanoes that do not explode, but the ones that do explode with a high sound and lots of hot magma, and some are very low and don't have a lot of magma. An explosive eruption always begins with some form of blockage in the crater of a volcano that prevents the release of gases trapped in highly viscous andesitic or rhyolitic magma. The high viscosity of these forms of magma prevents the release of trapped gases.

Are Pacific viperfish endangered
anyanavicka [17]

The viperfish is a heterotroph, not an autotroph due to the fact that it eats to live. Although it is not a common fish, the deep-sea viperfish population is seemingly stable. It is on neither the endangered nor the threatened species list.
