- Natural
Hazard
- Any natural events that has
the potiental to endanger
human life, the economy
and propety
- Atmosheric Hazards
- Weather hazard created in the
atmosphere, by weather and
climate
- Drought,
Hurricane,
Sandstorm
- Drought,
Hurricane,
Sandstorm
- Weather hazard created in the
atmosphere, by weather and
climate
- Geological Hazards
- Rock/Earth hazards. Created by
tectonic plates or surface rock
and soil
- Earthquake,
Volcanic
eruptions,
Tsunami,
Avalanche
- Earthquake,
Volcanic
eruptions,
Tsunami,
Avalanche
- Rock/Earth hazards. Created by
tectonic plates or surface rock
and soil
- Water Based Hazards
- Hazards created by
river, sea or oceans
- Flood,
Tsunami
- Flood,
Tsunami
- Hazards created by
river, sea or oceans
- Biological Hazards
- Any biological loiving
substance poses a threat to
the health of people
- Disease,
Forest fire
- Disease,
Forest fire
- Any biological loiving
substance poses a threat to
the health of people
- Some natural hazards can overlap categories, for
example tsunami can fit into multiple categories
because tsunami is created by the movement of
tectonic plates (geological Hazards) but the main
damage is done by water (Water Based Hazards)
- Atmosheric Hazards
- Any natural events that has
the potiental to endanger
human life, the economy
and propety
- Tectonic Plate
- Crust is the outer layer of the
earth. It is very thin, between a
thickness of 6km and 7km
- Constructive plate, movement of
the two plate moving apart,
magma rises up through the gap
forming a volcano
- Destructive plate, occurs
when the oceanic plate is
being forced under the
continental plate, this may
trigger earthquakes
- Oceanic and Continental plate differ because the
continental plate is lighter and thicker (made from
granite) than the oceanic which is thinner but
denser (made from basalt)
- Oceanic and Continental plate differ because the
continental plate is lighter and thicker (made from
granite) than the oceanic which is thinner but
denser (made from basalt)
- Conservative plate, occurs when
two plates slide past each other in
a different direction or in the
same direction but at different
speed
- Constructive plate, movement of
the two plate moving apart,
magma rises up through the gap
forming a volcano
- Mantle due to the high
temperature of thick layer, it has
consistency of jam. Temperature
range from mantle 5000 celsius
near the core to 1300 celsius just
below the crust
- Reasons why people want to live near
volcanoes
- Scientific purpose or
research
- Fertile lands to
grow crops
- Tourist attraction
- Geothermal energy
- Low house price
- Beautiful sights
- Scientific purpose or
research
- Reasons why people want to live near
volcanoes
- Inner core is solid, also made of iron. The
temperature in this core can be 5500 celsius
- Why would people not want to live
near volcanoes
- Volcanic eruption
- Pollutes river and water sources
- Climate change
- Landslide after eruption
- Posonous gas
- Volcanic eruption
- Why would people not want to live
near volcanoes
- Outer core is liquid
made of mainly iron
- Crust is the outer layer of the
earth. It is very thin, between a
thickness of 6km and 7km
