Balisevic. 4 Amazing planet Lots of satellites orbit (circle) the Earth taking photos and images that help scientists observe our planet in great detail. These photos come from a satellite that’s 830km above the ground. It sees wonderful things! © Cnes - Distribution Astrium Services/Spot Image World 5 Amazing planet © Virtualtourist.com Does this river flow through a huge old forest? No, it doesn’t! The satellite image (big picture) shows the Sao Francisco river flowing into the Parana river in Brazil. There are trees along the riverbanks. But behind the trees, the land has been farmed by people. You can see fields, villages and roads. You can even see a bridge across the river. An image like this helps people to watch out for flooding or to choose the best place to build bridges. 6 © Cnes - Distribution Astrium Services/Spot Image 7 DR Are these flying saucers that have landed in the desert? No! This is Saudi Arabia and the circles are fields of food crops, such as wheat. The water for the plants is pumped up from deep underground. In the middle of each field there is a hub or support, which holds up a 1km-long sprinkler. The hub turns the sprinkler above the plants, keeping them watered. The satellite’s infrared (sensitive to heat) technology lets agricultural engineers see how the wheat is growing. In the big picture, red shows where the wheat is ripening. World 8 © Cnes - Distribution Astrium Services/Spot Image 9 DR Why does almost nothing grow around this lake? Because its water is very salty. An explorer who found the lake in 1897 in the desert in Australia named it Lake Disappointment. Probably he had hoped to drink the water! Today, we explore the world with satellites. Their accurate images mean that maps of very remote areas in the world can be made. These are useful, for example, when rescue operations need to be organized.

But that's not always true. Breeders have created different varieties of pigs that we see today. Some have curly tails and others have straighter tails. Wild boars and wart hogs have tails that hang down. Some pigs have no tails at all! The € euro symbol The symbol € was the fifth letter in the ancient Greek alphabet. It’s called epsilon and was said like our letter e. It's also the first letter of the word Europa. She was a princess in ancient Greek mythology and Europe was named after her. The euro The Colosseum, a huge ancient theatre Rome Illustration: B. Lefort. It was built between 70 and 80 bce in Rome, the capital city of the Roman Empire. Amazing shows were held here: gladiator fights, animal hunts, pretend sea battles and public executions… Its nickname, the Colosseum, means huge place. It's real name was the Flavian amphitheatre (open air theatre of the Flavian emperors). © NewOpenWorld Foundation [...]...Bayard magazines more an a b Much ook! th Subscribe now !
