    • Natural Hazard
      • Is a natural process that causes risk to humans or there property
    • Hazard Risk
      • Is the chance or probability that causes risk to humans or there property
    • Natural Disaster
      • Is a hazard that has taken place
    • The distribution of natural hazards are: most of the natural hazards appear at the equator also in areas south of the development line. This means that LIC countries are more affected and less prepared.
    • Tectonic Hazards
      • Earth quakes
        • a sudden violent shaking of the ground, typically causing great destruction, as a result of movements within the earth's crust or volcanic action.
      • Volcanoes
        • a mountain or hill, typically conical, having a crater or vent through which lava, rock fragments, hot vapour, and gas are or have been erupted from the earth's crust
      • Convection Currents
        • Convection currents in the magma drive plate tectonics.

    • Weather Hazards
      • A weather hazard is an extreme weather event that threatens people or property. Weather hazards include: tropical storms. tornadoes. droughts.

      • Tropical Storms
        • A tropical storm is a hazard that brings heavy rainfall, strong winds and other related hazards such as mudslides and floods.
        • .Tropical storms usually form between approximately 5° and 30° latitude and move westward due to easterly winds.
        • The Coriolis force sends them spinning towards the poles.In most areas, tropical storms are given names.
        • .It is hard to predict the path of a tropical storm, and therefore difficult to manage an adequate evacuation of an area if needed.
      • Extreme Weather
        • An extreme weather event is weather that is different from the normal pattern that is normal pattern that is expected. An example of an extreme weather event is storm Desmond. Holmes and houses were damaged by flooding and high winds. this means that many homes were evacuated. the storm also damaged electricity.
    • Climate changed
      • Climate Change is the long term change in the weather
        • Global climate change take place over thousands of years
