2. The Forces of Nature
The sun’s heat
and light

3. The Forces of Nature
Air

4. The Forces of Nature
Water

5. The Forces of Nature

and light
Water
When they combine with water they become dangerous killers
They form disasters

6. Dangerous weather

7. Types of natural disaster
avalanchefloodhurricane
mud slip
tornado

8. HurricaneA violent storm, characterized by extreme fury and sudden changes of the wind,
and generally accompanied by rain, thunder, and lightning; -- especially prevalent
in the East and West Indies.

9. Flood

11. Tornado
A violent thunderstorm in western Africa or nearby Atlantic waters.

12. Mudslip
Water soaked soil; soft wet earth

13. Comparison between
Tornadoes Hurricanes
1(Tornado winds actually blow much
faster than hurricanes and can reach
450 kph.
2(They are not nearly destructive than
hurricane. They have fantastic power
that they can carry of people , cars and
even buildings.
3(Tornadoes cover an area of a few
hundreds metres wide.
4(Tornadoes are also called twisters.
1(Hurrican winds actually blow much
slower than tornadoes. The fastest
hurricanes wind speeds are little more
than half as great , they can reach a
speed of 240 kph or they can reach a
speed of just 118 kph.
2(They are more destructive than
tornadoes. They can destroy whole
countries in just hours.
3(Hurricanes may cover an area of 800
kilometres across.
4(Hurricanes are also called cyclones
or typhoons.

14. 1.Can we stop the forces of nature to avoid
making disasters?
Questions?

15. No, we can’t but we can forecast the time
when disasters happen by using modern
technology and satellites pictures.

22. 5.How can transport save lives?

23. By escaping by planes, cars or buses.
5.How can transport save lives?

24. 6.How can wealth save lives?

25. If you have much money. This means you have a car or a plane. When a disaster
happens, you can escape from it by using the car or the plane.
