changes due to volcanic eruption

• volcano - opening of the Earth's crust that allows magma to rise in the surface
• crater - the opening of a volcano
• magma - molten rock that is under the Earth's surface
• lava - magma that flows out on the surface of the earth
• volcanic eruption - release of the magma in the crater
• volcanic eruption:

  • explosive
  • non - explosive
• explosive - when large amount of pyroclastic materials are ejected by the volcano
• pyroclastic materials:

  • lava
  • ashes
  • volcanic glass
  • rocks
• non-explosive - lava just flows out in the crater and doesn't erupt
