Hurricanes & Tornadoes

In this table it shows us information about two strongest storms, hurricanes and tornadoes. They are both dangerous and destructive and there are a lots of differences between them.

First of all, The hurricane is classified on the Saffir-Simpson C1-5 scale, while the tornado is measured on the Fuji ta F0-F5 scale. The minimum speed of a hurricane is 74 mph, whereas that of a tornado is 40 mph. On the other hand, the maximum speed of a tornado, 250-300 mph, is higher than that of a hurricane, 155-200 mph . Whereas a tornado usually lasts from a few minutes to a few hours, a hurricane can last up to a week. A hurricane can be predicted 2-3 days in advance for a wide area and 6-10 hours beforehand for a locality, but a tornado can be predicted only minutes before it hits. Hurricanes start over warm oceans but tornadoes usually originate over land.

In brief, tornadoes are less predictable, last for a shorter period of time and can reach much higher wind speeds.

Car specifications

This table describes the different specifications of four types of car. It gives details of price, country of origin, engine capacity and fuel consumption.

Clearly, the most expensive of the four is the Volkswagen Golf. There is very little to choose between the other three. The German Volkswagen has the biggest engine at 1600cc. The Japanese Toyota Corolla and the American Ford Focus both have a capacity of 1400cc, with the Japanese Nissan Micra being the smallest in engine size with 1200cc. Not surprisingly, the smallest, the Micra, is the most economical in terms of fuel consumption and the Volkswagen the least so. Both the Ford and the Toyota are between the other two, and very similar in terms of fuel consumption.

As you'd expect, the biggest car, in terms of engine size, is the most expensive and uses most fuel as Volkswagen Golf, while the smallest, the Micra, is the cheapest in terms of both price and fuel costs.
