Title: Hazards


1
Hazards
  • Atmospheric
  • Tectonic
  • Oceanic

2
  • One of the most hazardous races known to manthe
    French

3
Atmospheric
  • Monsoon
  • Seasonal winds which bring torrential (heavy)
    rainfall
  • Acid Rain
  • This occurs when chemical fumes are
    released into the atmosphere
  • Fog
  • A mass of water vapour suspended in the air
  • Tornado
  • Strong winds whirling around a small area of
    extremely low pressure

5
It is widely considered that being cooked by
grannies is a Hazard
6
  • Hurricane
  • A severe often very destructive storm
  • Blizzards
  • Periods of heavy snowfall
  • Hail
  • This is when rain freezes into tiny balls
    and falls to the ground
  • Thunderstorms
  • A storm caused by strong rising air
    currents accompanied by thunder and
    lightning
  • Drought
  • A long period of little or no rainfall

7
Tectonic
  • Famine
  • Occurs only in third world countries,
    often when arid soil or little rain means
    that crops do not grow
  • Earthquakes
  • They occur on3 out of 4 plate boundaries
    when two plates rub together
  • Landslide
  • Often occurs as a result of deforestation, the
    loss of roots mean that heavy rainfall can
    wash away the top soil easily

I just love cleaning windows

  • Avalanches
  • Go hand in hand with landslides. So remember
    dont go yodelling (ha-ha and ha)
  • Quicksand
  • A deep mass of loose wet sand which
    submerges anything on top of it

12
Oceanic
  • Volcanoes
  • Many volcanoes appear underneath the water
    as well on land
  • Tsunami
  • A tsunami is a large tidal wave
  • Sea level Rise
  • Occurs as a result of global warming and
    the polar ice caps melting

Combination
  • Nearly all of the hazards are not just a result
    of the specific place they occur they often have
    been influenced by other factors.
  • An example of this would be
  • Forest fire, although the forest is on the earth
    the atmosphere can often be responsible for the
    fire
  • Desertification, for this to occur you need a
    hot dry climate to allow the earth to get that
    way
  • Flooding, this is most commonly found on a river
    and would not be possible without a larger than
    normal amount of rainfall which leads to flooding

15
  • A good example for a trio combination is
    sea-level rise, this is caused by global warming
    which in turn melts the ice caps which then cause
    an increase in water affecting both the oceanic
    ecosystems and places such as Bangladesh which in
    many places is only a metre above the ground
