51. Which of the following parts of the Hurricanes is/are correctly matched?
1. Eye: The hole at the center of the storm.
2. Eye wall: A ring of thunderstorms.
3. Rain bands: Contains thunderstorms and sometimes tornadoes.
Hurricanes are large, swirling storms. They produce winds of 119 kilometers per hour (74 mph) or higher. That's faster than a cheetah, the fastest animal on land. Winds from a hurricane can damage buildings and trees.
Hurricanes form over warm ocean waters. Sometimes they strike land. When a hurricane reaches land, it pushes a wall of ocean water ashore. This wall of water is called a storm surge. Heavy rain and storm surge from a hurricane can cause flooding.
Once a hurricane forms, weather forecasters predict its path. They also predict how strong it will get. This information helps people get ready for the storm.
There are five types, or categories, of hurricanes. The scale of categories is called the Saffir-Simpson Hurricane Scale. The categories are based on wind speed.
Category 1: Winds 119-153 km/hr (74-95 mph) - faster than a cheetah
Category 2: Winds 154-177 km/hr (96-110 mph) - as fast or faster than a baseball pitcher's fastball
Category 3: Winds 178-208 km/hr (111-129 mph) - similar, or close, to the serving speed of many professional tennis players
Category 4: Winds 209-251 km/hr (130-156 mph) - faster than the world's fastest rollercoaster
Category 5: Winds more than 252 km/hr (157 mph) - similar, or close, to the speed of some high-speed trains
Parts of a Hurricane
1. Eye: The eye is the "hole" at the center of the storm. Winds are light in this area. Skies are partly cloudy, and sometimes even clear.
2. Eye wall: The eye wall is a ring of thunderstorms. These storms swirl around the eye. The wall is where winds are strongest and rain is heaviest.
3. Rain bands: Bands of clouds and rain go far out from a hurricane's eye wall. These bands stretch for hundreds of miles. They contain thunderstorms and sometimes tornadoes.
