Hurricanes and Tornadoes Compare/Contrast
When this prezi spun, did you
feel dizzy? If you did, multiply that feeling by 50. Even if you multiplied it by 100, you wouldn't come close to the mind boggling 300 mph wind speeds of a tornado. Have you ever been to a beach when it was high-tide? The waves are about five feet higher than usual. Hurricanes cause the water to go 12 feet higher than that at heir best. You'll be surprised by how similar and different these natural disasters can be.
Tornadoes and hurricanes
may seem very different, but in several key ways, they are very similar.
For example, hurricanes
and tornadoes both have early warning systems. A hurricane or tornado watch means that the conditions are right for a hurricane or tornado to hit or form over your area. A tornado or hurricane warning means that a tornado or hurricane is near, is spotted, or is forming.
Another huge similarity
is, both of them can down houses before they are even at their best. A category 4 hurricane, the best being 5, is able to demolish a house. In a like manner, a tornado at F4 on the Fujita Scale, the most dangerous an F5, is able to obliterate a well constructed home.
Probably the most relevant
similarity is that whatever you do, don't be near a tornado or hurricane when it hits. They are some of the most dangerous natural disasters in the world. Hurricane Katrina cost the U.S $8,000,000,000. That's a pretty big price tag. In the Tornado Alley, tornadoes claim 90 lives a year. They are very, very dangerous.
Hurricanes are similar, but also are very different.
hurricanes and tornadoes spin at different speeds. Hurricanes at Category 5 spin at a maximum of 200 mph. Tornadoes are much faster. They spin at F5 at 300 mph at greatest.
An additional difference
between hurricanes and tornadoes is, when and where hurricanes and tornadoes form. Most hurricanes form over summer and fall, over the ocean. Tornadoes, on the other hand, form mostly during spring, and wherever the conditions are right.
Tornadoes and hurricanes are
also different in the way that they are measured. Hurricanes are measured by the Saffir-Simpson Scale, which divides hurricanes into them into five categories, 1, 2, 3, 4, and 5, five being the most destructive. Tornadoes, on the other hand, are recorded on the Fujita Scale. This scale divides tornadoes into 6 categories based off wind speeds. The categoies are; F0, F1, F2, F3, F4, and F5. F5 is the strongest of the categories.
Hurricanes and tornadoes are very similar, but their differences provide a useful way to tell them apart.
Thank you for reading
this prezi on hurricanes and tornadoes. But remember that if there is a tornado or hurricane in your area, listen to the advice that they give you on the radio and TV, and take shelter or get out of your area.
Hurricanes and earthquakes are two of the most dangerous natural disasters in the United States. They can be very disastrous and deadly. In the United States, there have been 73 hurricanes since 1954. Earthquakes are harder to detect because they have to have at least a magnitude of 5 ("Earthquakes per year," 2009). The amount of earthquakes detected in the United States was 1656 in the past 10 years ("Earthquakes per year," 2009). The World Meteorological Organization is the organization that can choose the names of hurricanes. At the beginning of the year, the first hurricane always begins with an A name, and continue down the alphabet (NHC, 2003). The letters not used to name a hurricane are, Q, U, X, Y, and Z (Netting, 2003).
HurricanesHurricanes are one of the most dangerous natural disasters for an area to endure. Hurricanes consist of powerful fast winds and heavy rain. A hurricane is a low tropical storm with winds exceeding 74 MPH that can easily damage property and buildings or even kill individuals in its path.
A hurricane occurs when heat is released in the form of large amounts of water vapor condensed that heat up the air and reduce air pressure close the ocean surface. This action causes air to move quickly inward creating a circular motion around the low pressure area. The circular winds form an upright cylinder that can extend upward for many miles. Most hurricanes initiate out in the ocean and gain strength, speed and energy as they travel across the ocean waters. Once a hurricane hits land, it usually loses its strength and speed as a result of friction from items that it encounters in its path.
