Research Question-How is the speed and the powerful of a Hurricane?

A hurricane is a powerful,spiraling storm that begins over a warm sea, near the equator . When a Hurricane hits land,it can do great damages through its fierce with,torrential rains, inland flooding , and huge waves crashing ashore . A powerful hurricane can kill more people and destroy more things and any natural disaster. a hurricane is very powerful , sometimes violent storm with winds and heavy rains. The wind speeds must reach an excess of 156 mph or 251 KM/hr. these storms are so  powerful , it mandatory all the way up to 10 miles from shoreline. Also the powerful the range can get is to 75 and 95 mph

Research Question-How Long Do Hurricanes Last?

Hurricanes have a life span of 1 to 30 days. They weaken and are transformed into extratropical cyclones after prolonged contact with the colder ocean waters of middle latitudes, and they rapidly decay after moving over land areas.There are a few hurricanes that have survived for few hours, where others have moved around for several weeks before getting diluted and fading out. The existence of an hurricane is also about 9 days. Usually, storms infused in the month of August live the longest, with an average of 12 days. This is because they build up in the eastern part of the North Atlantic and pass through the long water path for several days before re-curving northward.

Research Question-How are Hurricanes Formed?

A  tropical thunder storm can grow into a massive hurricane under certain conditions . sometimes several thunder storms start rotating around a central area of low pressure . this is called a tropical depression . If the depression strengthens so that winds reach at least 39 mph , it is called a tropical storm. And if wind speeds increase to more than 74 mph, it is called a tropical cyclone or hurricane. Once formed , hurricanes take energy from the warm ocean water to be become stronger.A storm will strengthen if there is a supply of warm , moist air is found above warm it will continue to grow . A hurricane dies when it moves away from the tropics . When a hurricane moves into areas with cooler ocean water,it weakens . It will also weaken if it travels over land.
