In what way are hurricanes and tornadoes similar?A.Both are powerful rotating storms.B.Both can reach wind speeds of 300 miles per hour.C.Both usually form over land.D.Both can travel over 1,000 miles.

Where do hurricanes form?

_________ form as warm core cyclones over land, and can lead to tornado formation.

Choose the correct answer to each of the questions from 1 to 5.          Tornadoes are giant rotating columns of air. They form in thunderstorms when there is a great difference in the temperature and humidity of the lower and upper atmosphere. They can be very dangerous and very destructive.         There are different varieties of tornadoes. They can be very big or small. Some tornadoes are only a few feet across and others can travel across an entire state. Tornadoes stretch from the ground high into the sky. Usually, people rate them from F0 to F5, F5 being the most dangerous with wind speeds of around 261- 318 miles per hour. They are a very violent force of nature and can lay whole towns completely flat.        Tornadoes can happen all over the world but a lot of them happen in the central United States in a region called Tornado Alley. Tornado Alley is made up of the low, flat states of the central United States between the Rocky Mountains and the Appalachian Mountains. Even though Tornado Alley is the most common place for tornadoes, the deadliest recorded tornado was in Bangladesh in 1989 and killed around 1,300 people. Recently, massive tornadoes destroyed large parts of Alabama in the United States, a state that does not usually have tornadoes.Question 18.Which of the following is NOT true about tornadoes?A.They can happen all over the world.B.Most are very large.C.They come in many sizes.D.They can be very destructive.Question 19.What does the word “them” in the passage refer to ?A.the tornadoesB.the peopleC.Tornado AlleysD.states of the USAQuestion 20.Where do most tornadoes happen?A.In the Central United StatesB.In the western United StatesC.Everywhere in the worldD.In BangladeshQuestion 21.The word “varieties” in the passage is closest in meaning to …….A.regionsB.powersC.typesD.sizesQuestion 22.What would be a good title for this passage?A.How and where tornadoes happenB.The worst recorded tornadoesC.Bad tornadoes in the United StatesD.The most destructive storms of nature

Hurricanes that affect the US usually form in the Northern Atlantic Ocean. As solar radiation warms the ocean surface evaporation increases. The warmer the temperatures, the greater the rate of evaporation. As you may recall, warm, moist air rises, expands and cools to the dew point and clouds form. Energy and water vapor continue to be added to the atmosphere. This creates a low pressure area, known as a tropical depression. If winds are sustained above 39 miles per hour it is considered a tropical storm. If the winds are over 74 miles per hour it becomes a hurricane. Most hurricanes occur in late summer early autumn because this is when the ocean surface is warmest. They are the most destructive storms. High winds, storm surges (ocean water pushed onto the coast) and major flooding occur. One more thing that adds to the hurricane Category Winds 1 74-95 mph 2 96-110 mph 3 111-130 mph 4 131-155 mph 5 > 155 mph disaster is that tornados can form. A hurricane is sometimes referred to as a cyclone because it is such a large area of low pressure. A typhoon is the same as a hurricane, however forms over the Northwest Pacific Ocean. Hurricanes are fairly easy to predict because advancements in weather radar and satellite technology allows meteorologists to watch them develop and keep track of their path. Where exactly they hit land is not full proof. If a hurricane appears to pose a threat to your area within 48 hours, a hurricane watch is issued. A warning is issued if conditions are expected within 36 hours. When you are ordered to evacuate LEAVE THE AREA. Need to know: 1. Where do hurricanes form? 2. How do clouds form in a hurricane? 3. What is added to the atmosphere to fuel the development of a hurricane? 4. What is a tropical depression? 5. What is the difference between a tropical storm and a hurricane? 6. What is the difference between a sustained wind and a wind gust? 7. How fast are sustained winds in a category 5 hurricane?
