Indirectly, yes. A "fire tornado," more properly called a firewhirl is not a true tornado and in terms of wind speed is only equivalent to an EF1 tornado. However, firewhirls act to spread fires, which can burn down entire neighborhoods if left unchecked.
it can destroy everything
Yes. A strong enough tornado can destroy just about any manmade structure. A tornado of high EF3 intensity or stronger should be enough.
Tornadoes can destroy everything from trees to homes and large buildings.
A funnel volcano is the most common tornado and is what most people think of when you mention a tornado. They are very violent and destroy almost everything in their path.
Technically, a tornado does not "destroy everything". In fact, it's path is completely unpredictable and random.A tornado doesn't "go" anywhere after it "destroys everything" because it isn't really intended to destroy things. A tornado could appear in a place where there is very little nature and very barren.The tornado will simply "fade away" or stop, and will just "go away". When, exactly is unknown, since tornadoes have a wide range of times in which they will last.
a tornado in the form of fire
Yes. A tornado F3 or higher intensity could definitely destroy a mansion.
The "fire tornado" forms from the fire; it doesn't really matter how the fire starts. Also, a "fire tornado" is more properly called a fire whirl as it technically isn't a tornado.
a tornado in the form of fire
Yes. In a strong enough tornado wind and debris carried by the wind can destroy houses.
A tornado can cause damage that you do not want to see. It can destroy animals' habitats and kill plants by uprooting trees and destroying flowers. A tornado could break your home or vehicle! A tornado damages everything in its path.
It depends on how strong the tornado is. A weak tornado (EF0 or EF1) will generally only destroy small trees and weakly built structures such as sheds and fences. Stronger structures will only take minor to moderate damage. A strong tornado (EF2 or EF3) will destroy most trees, vehicles, and some buildings. A violent tornado (EF4 or EF5) will destroy just about everything in its path.
