Options:

A) magma’s composition

B) magma’s temperature

C) size of the volcano’s cone

D) concentration of dissolved gases in the magma

Answer:

B) magma’s temperature

Explanation:

In explosive eruptions we can observe:

  • The lavas are very viscous, flow with difficulty and prevent the release of gases, thus causing violent explosions;
  • Because of its viscosity, lava sometimes does not spill, forming rounded structures that are called domes or domes;
  • In some situations, the lava solidifies even inside the chimney, forming volcanic needles, which may later be evident in cone erosion.
