3. The causes of the tornado that it's the hot/ cold front the
funnel cloud. As will when the temperature change that also
one of the causes. When the tornado happen its start with
wind then the wind got bigger . Which mean that the wind help
the tornado to create
9. • The second evidence i found that show how
many tornadoes that happened from the 1950th
until 2010. That also show how strengthen the
tornadoes in each year. I think it's important to
show how dangerous is every single year. That
also show that every year the tornados become
stronger than before. Which means that will
become more worse for the people and for the
national disaster

Editor's Notes
CONCLUSIONSI thinks if this pattern continues for the next 100 years a lot of things will happen. The national disaster will become more worst every year. Everything that I had been found that showing that it will be worst every time. Which mean there a lot of people will be in danger of the tornadoes. I thinks everything will be completely destroy. Because everything I found from information that and show a bad news for the national disaster.
