Question

Distinguish between the different ways volcanoes cause damage.

Answer 1

Answer:

Volcanoes spew hot, dangerous gases, ash, lava, and rock that are powerfully destructive. ... The most common cause of death from a volcano is suffocation. Volcanic eruptions can result in additional threats to health, such as floods, mudslides, power outages, drinking water contamination, and wildfires.

Answer 2

Thre basic types of magma:

Mafic or Basaltic-- SiO2 45-55 wt%, high in Fe, Mg, Ca, low in K, Na Intermediate or Andesitic-- SiO2 55-65 wt%, intermediate. in Fe, Mg, Ca, Na, K Felsic or Rhyolitic-- SiO2 65-75%, low in Fe, Mg, Ca, high in K, Na.

There are 5ways in which volcanoes causes damage according to their magma

i) Icelandicii) Hawaiianiii)Strombolianiv) Vulcanianv) Peleanvi) Plinian

In this case, however, fluid lava flows from a volcano’s summit and radial fissures to form shield volcanoes, which are quite large and have gentle slopes.

Because of such small frequent outbursts, Stromboli volcano, located on Stromboli Island off the northeast coast of Italy, has been called the “lighthouse of the Mediterranean.”

This mixture forms dark, turbulent eruption clouds that rapidly ascend and expand in convoluted shapes.
