Natural Disasters Preparing for the Worst! Video Slide 2 What
Are Natural Disasters? Any event or force of nature that causes
catastrophic repercussions Any event or force of nature that causes

Avalanches An avalanche is a very large slide of snow or rock down
a mountainside. Its caused when a buildup of snow is released down
a slope. It is a major danger in the mountains. It is caused by
sounds or shockwaves of sounds. It is dangerous and sometimes
deadly. An avalanche is a very large slide of snow or rock down a

sudden release of stored energy in the Earths crust. This creates
seismic waves. They can destroy cities. A phenomenon that results

Volcanoes An eruption at the weak spots of the Earths crust, where
it is easiest for magma to burst through. Extremely hot. It cools
down and turns black. An eruption at the weak spots of the Earths

of waves created when a body of water, such as an ocean is rapidly
displaced on a massive scale. The name is Japanese and it causes
major floods. A series of waves created when a body of water, such

Slide 10 Droughts A drought is a period of time when there is not
enough water to support agricultural, urban, human, or
environmental water needs. This can wipe out a city. It occurs over
time and results in a loss of food for the population. A drought is

water. It is an expanse of water that submerges land. A flood is an

is in contact with both a cloud base and the surface of the Earth.
The warm and cold air mix together. A violently rotating column of

Tsunamis A tropical cyclone characterized by a low pressure center
and thunderstorms. This results in strong winds and flooding rain.
The rainstorms cause flooding and the winds cause damage. A

14 Forest Fires A forest fire is an uncontrollable fire, often
occurring in wild land areas. It can consume houses or agricultural
resources. It is difficult to stop the spread. A forest fire is an
uncontrollable fire, often occurring in wild land areas. It can
consume houses or agricultural resources. It is difficult to stop

storm with very heavy winds. The winds are at least 74 m/hr video
Slide 16 Ice Storms A severe weather condition with freezing
precipitation. Such a storm forms a glaze on objects, creating
hazardous travel conditions and horrible living conditions. Loss of
power frequently occurs, sometimes for extended periods of time. A

Likely Occur In Montreal? Ice Storms We are very lucky that Canada
does not suffer much from Natural Disasters. This is due to our
geographic location. We are very lucky that Canada does not suffer
