Román Pizzuti y Jeremías Buldo

3. Causes
gases that contribute to the greenhouse effect include:
● Water vapor
● Carbon dioxide
● Methane
● Nitrous oxide
● Chlorofluorocarbons

EKOenergy

5. 10 types of consequence:
1. Warmer temperatures
The accumulation of polluting gases causes temperatures to rise
more and more and that the climates change: this causes
droughts and, in addition, increases the risk of fires that lead to
deforestation and desertification of the planet.

7. 2. More intense storms
Thunderstorms produce lightning and heavy rains,
and can produce hail, tornadoes, and strong winds.
Heavy rains can cause flash floods, an effect that
causes drowning to more people every year than
tornadoes, lightning or hurricanes.

9. 3.Climate change is affecting the spread of
infectious diseases worldwide, according
to an international team of researchers,
with serious consequences for human
health and biodiversity conservation.

11. 4. Stronger heat waves
The global warming of the planet caused by the
accelerated burning of exhaustible fossil fuels has
been very intense in the North Pole. This makes
the North Pole much hotter today than fifty years
ago.

13. 5.Melting glaciers
Oceans with higher temperatures are oceans
that melt the ice of the polar ice caps: this
means that the sea level increases.

15. 6. More dangerous hurricanes
The rise in sea temperature causes hurricanes to
become more violent. Why? Because a hurricane is
the means that the planet has to distribute the
excess heat from the hot zones to the coldest. And
at a higher temperature, more hurricanes, with all
the problems involved: destruction of cities, crops,
dismantling of all systems, diseases

17. 7. Change of ecosystems
A higher temperature, less rainfall, droughts and
floods make the climate adapt to this new climate
and, therefore, there are changes in the duration
of the seasons, appear more typical patterns of
monsoon climates ...

19. 8.More expensive foods
Climate change threatens the production of
foods as basic as wheat, and this means that
hundreds of thousands of people whose lives
depend on their crops are at risk of losing
everything

21. 9.Disappearance of animal species
Many species of animals are seeing how their
current climate disappears and they are not able
to adapt to changes so quickly. Thus, many
polar bears are drowning because they cannot
reach the floating ice

23. 10. sea level rise
As the ice caps melt, much more water is
poured into the seas and oceans and
therefore the sea level rises: this is one of
the most serious consequences of climate
change

25. How can we stop global warming?
⥀ First ,we must to start recycling more objects like plastic or glass, the trash
is awful for our planet
⥀ Change the normal bulbs for the LED bulbs (low consume) help to save the
CO2 gases (one of the worse gases in the greenhouse effect)
⥀ start planting trees will help the planet because the trees absorb the CO2
gases in the atmosphere
⥀ sensitize people about help the planet is probably the best way to stop this

26. EARTHQUAKES

27. Causes:
● Cave sinking
● Underground
activity caused by
an erupting
volcano
● Nuclear tests

28. Consequences:
● If there is a earthquake
there can be urban
destruction.
● If there is a earthquake
there may be house
collapse
● If there is a earthquake,
the populations life
claimed, specially if it is
not prepared for this type
of events.

29. earthquakes in latin america
and in the world:

30. Earthquake in Chile on May 22, 1960 magnitude 9,5
Consequences:
Trick eruptions of volcanoes and tsunami that
destroyed many Chilean cities to cross the pacific
ocean and causes consequences in faraway places like
japan or the Philippines , where arrived after 15 hours

31. Chile a place where earthquake of
are counted

32. Earthquake in Haiti on January 12 , 2010 with an
2 mount of 300,000 dead
Indonesia : December 26, 2004, magnitude 9,3

33. Main emergency measures against earthquakes
● Go to the established security
zone .
● If you are in a building , do not use
the elevator
● Always have an emergency
number at hand
● Do not run
● Check in fires have occurred
● Collaborate with the authorities
● And many more measures
● Check in fires

35. “Tsunamis”
By Matías Gonzales, Rodrigo
Mara, Joaquin Barrio and
Ismael Achenapure

36. Catastrophic cases around the world
Tsunami krakatoa: In 1883, 27th August, krakatoa’s volcano
registered multiple eruptions that cause what caused that one of his
sides will open and allowed an encounter between the magma and
the ocean.
This tsunami caused 36.000 deads

37. Causes
- Tremors
- Volcanic Activities
- Landslides

38. Consequences
There’s a lot of consequences, and
these are some of the many
consequences around the world
caused by tsunamis.

39. Destruction
The amount of energy and water contained in a huge tsunami can cause extreme
destruction when it strikes in a land.
The initial wave is extremely tall; however, most damage is not sustained by this wave.
Most of the damage is caused by the huge mass of water behind the initial wave front, as
the height of the sea keeps rising fast and floods powerfully into the coastal area. It is the
power behind the waves, the endless rushing water that causes devastation and loss of life.
When the giant breaking waves of a tsunami batter the shoreline, they can destroy
everything in their path.

40. Death
One of the biggest and worst effects of a
tsunami is the cost to human life because
unfortunately escaping a tsunami is nearly
impossible.

41. Diseases
Tsunami waves and the receding water are very destructive to structures in
the run-up zone. The areas close to the coast are flooded with sea water,
damaging the infrastructure such as sewage and fresh water supplies from
drink.
Flooding and contamination of drinking water can cause disease to spread
in the hit tsunami hit area.

42. Environmental impacts
Tsunamis not only destroy human life, but have a devastating effect on
insects, animals and natural resources. Land animals are killed by
drowning and sea animals are killed by pollution if dangerous chemicals
are washed away into the sea, thus poisoning the marine life.

44. WHAT ARE FLOODS?
● Floods are natural disasters, in these disasters a lot people died and families
lost their houses
● In the twentieth century 3,2 millions died about this disasters
● It is a very big occupation by the water in dry zones.
● The factors: temporary rise of lake level, river or sea.

45. CAUSES
The first causes of floods are heavy rain.Too much precipitation
● The river rises
● Human activity. For example: the deforestation.
● If many sediments accumulate, large amounts of water will flow logs and
stones.
●
Severe winds over water
Unusual high tides

46. CONSEQUENCES
● Economical: Lost of materials, people lost their houses and destruction of
those houses.
● Environmental: Pollution, damages in agricultural lands, crops, food
production, animals and humans.
● Health: Increase of the risk of fecal-oral transmission diseases. We can suffer
injuries as a result of fallen trees and power lines.

47. POSSIBLE SOLUTIONS
● We should not throw away rubbish in the streets.
● We should create a system
● Capturing the carbon dioxide emitted by biofuel plants and storing it
underground.

48. FOREST FIRES
By Siebert, Acosta, Barone, De
Luca, Diaz and Novelletto

49. Causes
They always start by one of two ways: naturally caused or
human caused.Firstly natural fires are generally started by
lightning. Secondly human caused fires can be generated by
smoking,burning grass,burning trash and the elimination of
trees for the creation of grazing areas,etc.
Human caused fires constitute the greater percentage of
forest fires, but natural fires constitute the great majority of
the total area burned.This is because the human caused fires
are usually detected early,therefore they are usually

50. Consequences
Forest fires increase carbon dioxide levels in the atmosphere, contributing
to the greenhouse effect and climate change. In addiction, ashes destroy
much of the nutrients and erode the soil, causing flooding and landslides.
The ground, without plants to stabilize ir is susceptible to being washed
away by rainwater, especially on steeply sloped areas.
Insects are the first to lose their lives to heat and smoke. also eggs, which
were laid in trees, etc. are destroyed
Natural cycles of forest are interrupted and native species disappear,
while invasive plants proliferate

51. FIRE BEHAVIOUR
This behaviour is influenced by how fuels, weather and
topography interact.
Once a fire starts, it will continue burning if there is heat,
oxygen and more fuel present.These three elements form the
“fire triangle”.
To control the “fire triangle” firefighters use:
❏ Water, foam, dirt to cooling fuels below the combustion
temperature.

52. Examples of forest fires
❏ Forest fire in Australia ❏ Forest fire in California

53. ❏ Forest fire in China ❏ Forest fire in the center
of Santander

54. ❏ Forest fire in Tokyo ❏ Forest fire in Minnesota

55. Solutions for this big problem
1- make sure you are following all the local regulations and laws
2- keep up to day with the weather forecast
3- only light fires in areas that are easily controlled locations
4- do not burn any material that are combustible or unusual in nature
5- if you go camping make sure to teach your children the rules and safety
precaution of camping.

56. How can we prevent forest
fires from happening
● never leave a fire unattended,
● if you use to use fueling lanterns, stoves, and
heaters, be careful of them
● never play with matches or lighters
● if you see dead debris on the floor, you have
to clean it up.

57. Hurricanes

58. What are hurricanes?
● Hurricanes are large, swirling storms.
● They produce winds of 119 kilometer per hour or more
● they form over warm ocean water
● they are faster than cheetah, the fastest animal on land
● IF A HURRICANES OCCURS, THE WIND IS STRONG

59. What happens when they hit land?
When the hurricane approaches land, the outer edges begin to incorporate
the air over the land and transfer them inward toward the eye. This
creates strong areas of convergence that helps spawn weather phenomena
such as thunderstorms and tornadoes.
IF A HURRICANE APPROACHES LAND, THE OUTER EDGES BEGIN TO INCLUDE THE AIR
OVER THE LAND.
Even as the hurricane grows weaker over land, the wind field tends to
increase, spreading the hurricane's effect over a much wider area. The
outer areas of the hurricane may even see an increase in wind speed,
while the average maximum wind speed decreases. The effect of a larger
wind field along the coast can cause more storm surges and larger waves.

60. Types of hurricanes
Once a hurricane forms, weather forecasters predict its path. They also
predict how strong it will get. This information helps people get ready for
the storm.
There are five types, or categories, of hurricanes. The scale of categories is
called the Saffir-Simpson Hurricane Scale. The categories are based on wind
speed.
● Category 1: Winds 119-153 km/hr (74-95 mph) - faster than a cheetah
● Category 2: Winds 154-177 km/hr (96-110 mph) - as fast or faster than a
baseball pitcher's fastball
● Category 3: Winds 178-208 km/hr (111-129 mph) - similar, or close, to the
serving speed of many professional tennis players
● Category 4: Winds 209-251 km/hr (130-156 mph) - faster than the world's
fastest rollercoaster
● Category 5: Winds more than 252 km/hr (157 mph) - similar, or close, to
the speed of some high-speed trains

61. The parts of hurricanes
EYE: The eye is the "hole" at the center of the storm. Winds
are light in this area. Skies are partly cloudy, and
sometimes even clear.
Eye wall: The eye wall is a ring of thunderstorms. These
storms swirl around the eye. The wall is where winds are
strongest and rain is heaviest.
Rain bands: Bands of clouds and rain go far out from a
hurricane's eye wall. These bands stretch for hundreds of
miles. They contain thunderstorms and sometimes tornadoes.
