In what two ways does a tornado cause damage to property

It can make houses collapse
damage such as inside things can break ect
environmentally the tornado will cause a lot of damage
I think it can cause floods!!

It is useful for historians to write narratives so that history can be passed on from their point of view.  think about a story being told in third person, then think about it again being told in first person, by someone who actually experienced the event.

Well, a and b together would be negative. b alone would also be negative.
