This table gives us information about two strong winds, hurricanes and tornadoes. Both are dangerous and destructive but there are important differences between them.
Firstly, 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. The hurricane is classified on the Saffir-Simpson C1-5 scale, while the tornado is measured on the Fujita F0-F5 scale. 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
Table of car specifications
Make Price Country of origin Engine size Miles per gallon
Toyota Corolla $15,550 Japan 1400cc 48
Volkswagen Golf $18,250 Germany 1600cc 40
Ford Focus $15,800 USA 1400cc 50
Nissan Micra $15,500 Japan 1200cc 52
Types of car
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, while the smallest, the Micra, is the cheapest in terms of both price and fuel costs.

Date producing countries in 2001
Top 10 date-producing countries
The bar graph shows date production in tonnes for the world's top producers in 2001. Ten countries in the Gulf region and North Africa are featured.
First, Egypt was responsible for the lion's share of production, with over a million tonnes, but Iran was a close second, with almost 0.9 million. Following them came the UAE and Saudi Arabia, rivalling each other with about 740,000 tonnes each. Pakistan and Iraq, with outputs of approximately 630,000, were not far behind. The rest of the nations, however, were far less productive. Algeria supplied the world with nearly 400,000 tonnes and Oman around quarter of a million. In contrast, the harvests in Libya and Sudan were far less plentiful, yielding under 0.2 million each.
In summary, date production was most abundant in Egypt and Iran. In contrast, the countries with the smallest output were Libya and Sudan.
