Bernoulli's principle states that as the speed of a fluid (or air) increases, its pressure decreases. During a tornado, the fast-moving air above the roof creates low pressure, while the slower-moving air below the roof creates higher pressure. This pressure difference can create lift force that can cause roofs to be lifted during a tornado.

What damage can an F1 tornado do?
An F1 tornado can cause moderate damage, including breaking branches off trees, damaging roofs, overturning mobile homes, and moving automobiles. While it is considered a weak tornado on the Enhanced Fujita scale, it can still be dangerous and pose a threat to people and property.
What is the wind speed of an EF1 tornado?
Estimated winds for an EF1 tornado are 86-110 mph.
What does an F1 tornado do?
F1 damage is generally describes as moderate. Typical F1 damage includes broken windows, severely stripped roofs, badly damaged or mostly destroyed trailers, and collapsed garages and porches.
How can a tornado affect a structure?
Flying debris can shatter windows and doors. If the tornado is strong enough, it can blow the roof right off of a building or knock down walls. In the worst cases, structures can be leveled to the ground or even completely blown away. The severity of damage can be rated on the Enhanced Fujita (EF) scale.

How fast would winds be moving in a tornado tore roofs off buildings?
Winds in a tornado that are strong enough to tear off roofs from buildings can reach speeds up to 200-300 mph (320-480 km/h). This extreme wind speed, combined with the rotating nature of tornadoes, creates incredibly destructive forces that can cause significant damage to structures in their path.
How do tornadoes lift roofs off building using Bernoulli's principle?
Tornadoes lift roofs off buildings mainly through the combination of strong winds and pressure differences created by the swirling vortex of air. Bernoulli's principle plays a role by contributing to the lowering of pressure above the roof, creating lift force. This, along with the internal pressure of the building, can lead to the roof being lifted off during a tornado event.

How does it look after a tornado?
It depends on how bad the tornado was. A relatively weak tornado will topple trees and power lines, damage roofs, and destroy some weaker structures. After an intense tornado many homes may be destroyed or be without their roofs. Debris is scattered everywhere. After a large, violent tornado neighborhoods may be turned into fields of debris with trees stripped of their leaves and bark.
Why do roofs blow off during a tornado?
There are a few mechanisms. First, the wind going over the upward-pointing roof creates and upward force owing to Bernoulli's principle. The wind may also catch the roof under the eaves or cause a gable to fall inward and pick up the roof from below.
How roofs are lifted off buildings in tornadoes using Bernoulli's principle?
During a tornado, a drop in air pressure near the roof creates a pressure difference between the inside and outside of the building. This pressure difference causes an uplift force on the roof due to Bernoulli's principle, where air moves faster over the roof, creating a lower pressure on top that can lift the roof off.
What damage can an F1 tornado do?
An F1 tornado can cause moderate damage, including breaking branches off trees, damaging roofs, overturning mobile homes, and moving automobiles. While it is considered a weak tornado on the Enhanced Fujita scale, it can still be dangerous and pose a threat to people and property.
What is the prepotitional phrase in The tornado uprooted trees and roofs of houses were blown away?
The prepositional phrase in the sentence is "of houses." A prepositional phrase includes a preposition (in this case, "of") and its object (houses). This phrase functions as an adjective, providing more information about the roofs that were blown away.
How big is an F2 tornado?
An F2 tornado does not have any particular size. That is not how the scale works; it rates tornadoes based on damage. An F2 tornado (EF2 as of February 2007) is a tornado that tears roofs from well-built homes, derails trains, and destroys trailers. Winds in an EF2 are estimated at 111 to 135 mph.
What is an F-3 tornado like?
An F3 tornado is pretty destructive. In the areas hit hardest well built houses will have their roofs removed and multiple, possibly most walls collapsed. Weaker structures will be completely destroyed. In such a tornado cars are tossed an trains derailed.
What damage is likely to occur with an F1 tornado?
Typical F1 tornado damage surfaces peeled from roofs, windows broken, garages and porches collapsed, trailers overturned or severely damage, and trees knocked down.
How bad an is EF2 tornado?
An EF2 tornado is considered to be a significant tornado with wind speeds between 111-135 mph. It can cause considerable damage to buildings and vegetation, overturn vehicles, and pose a threat to human life. Preparedness and quick response are crucial in minimizing the impact of an EF2 tornado.
What destruction can a tornado cause?
Damage could range anywhere from minor damage to roofs and siding to the complete obliteration of well-constructed buildings
