Volcanoes

• Crust

  • The thinnest layer the earth
  • It is mainly made out off granite and rocks
• The Mantle

  • Thickest layer of the earth
  • Made of solid and melted rock
  • It slowly moves
• The Core

  • It is as hot as the sun
  • Its the deepest layer of the earth
  • Made mostly of nickel and iron
• Cause of Volcanic Eruptions - Constructive plate boundaries, convection currents in the mantle cause the tectonic plates to move apart, allowing magma to escape. This can make new land.
• Causes of Volcanic Eruptions - Destructive plate boundaries, here the plates move towards each other due to convection currents and one is forced under, causing an eruptions.
• Negative Impacts are plyroclastic flow, Larhar, Volcanic bomb, Ash, Tsunami
• Positive Impacts - Tourism, Fertile Soil, New land formations, Geothermal energy, Raw materials,
