How fast can a dog run?

Some breeds of dog can run much faster than others, and the fastest dog of all is the greyhound. A fully grown greyhound can run at the astonishing speed of about 56 k.p.h., that is, at nearly a kilometers a minute. Because greyhounds runs so fast, greyhound racing is a popular sport. At a Greyhound racing track, the dogs are put in a series of boxes called traps. Then an electrically-driven imitation hare starts to move round a rail running beside the track. As the hare runs past the traps, the doors are released and in their excitement the dogs rush out in pursuit. As in horse racing, people place bets on which dog will be first past the winning post.

Where is Pampa?

The Pampa is a region of grassland in Argentina. It runs inland from the town and cities, such as Buenos Aires on the Atlantic coast, and stretches for hundreds of miles up to the foothills of the Andes. The Pampa is very like the great plains, or prairies, of north America which stretch across the states of Texas, Kansas and Nebraska. Like the prairies, the Pampa is most famous for its cattle ranches, and the cowboys which look after the herds of cattle as they roam across the plains. One of Argentina’s most important exports is beef, which comes from the huge cattle ranches which are situated on the Pampa.

What is a king crab?

The King crab, or horseshoe crab, is not really a crab at all. In fact it is not even a crustacean but a very primitive arthropod which belongs to a group of its own. From fossil evidence we know that king crabs were abundant in seas about 175 million years ago. The few species that survive today are virtually unchanged from those early ancestors and for this reason they are sometimes called 'living fossils'.
King crabs have some unusual features. They are about a foot across, have heavy domed shell divided by a joint across, have a heavy domed shell divided by a joint across the middle, four pairs of walking legs and a long spiky tail. The bony mouth extends between the bases of the legs which help in chewing up the food. These characteristics, together with their gills and mouthparts, tell us that the King crab is actually descended from the forerunners of another group of arthropods adapted for life on land-the arachnids. These include the scorpions, spiders, mites and ticks, and daddy long legs or harvest men.

What’s the Difference between a star and Planet?

A star is a huge ball of hot, glowing gases, which whirls in space. All stars are made up of the same two gases, hydrogen and helium, and they shine by their own light, which is produced as a result of atomic reactions in their centre, causing great heat.

Planets are different. A Planet is much smaller and more solid than a star. It does not shine by its own light, because it is not nearly hot enough to produce that light. Instead, it shines by the light of the nearest star.

Our sun is a star, and in its solar system there are nine planets-Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto.
