II. Read the passage. Then answer the questions. LHT 
 A tropical cyclone is a circular air movement over the warm ocean waters in the warm part 
of Earth near the equator. Most tropical cyclones are storms with strong winds and heavy rains. 
While some tropical cyclones stay out in the sea, others pass over land. This can be dangerous 
because the winds and floods can break things and drown people.
Tropical cyclones form when warm, moist ocean air rises. They begin as a group of storm winds 
when the water gets as hot as 27°c or hotter. The Coriolis effect made by the Earth’s rotation 
causes the winds to rotate. These storms usually move westward in the tropics, and later move 
north or south into the temperate zone. 
 The term “tropical cyclone” is a general term and includes regionally specific terms such as 
“hurricane” and “typhoon”. A tropical cyclone that forms in the Atlantic is called a hurricane. 
The same is true of those that form in the eastern, central and northern Pacific. In the western 
Pacific a tropical cyclone is called a typhoon. In the Indian Ocean they are called “cyclones”. 
The name for a tropical cyclone depends on its location.
B. Answer the questions. 
1. Is there any tropical cyclone that begins and ends in the sea?
___________________________________________________________________________
2. Is it possible for a tropical cyclone to begin at the temperature of 26°C?
___________________________________________________________________________
3. What makes the winds rotate?
___________________________________________________________________________
4. Can we say both hurricane and typhoon are tropical cyclones?
___________________________________________________________________________
5. Where is a tropical cyclone called “hurricane”?
