Who was the first Olympic champion?
Who was the first Olympic champion?
The first Olympic Games were held in Greece in 776 BCE. There was only one event-a sprint of 200 m (600 ft) in which the competitiors ran naked! The winning runner was a male cook called Koroidos. The prize for the athletes back then, along with great fame, was a wreath of olive leaves and a statue of them placed at Olympia. The modern Olympic Games take place every four years with (fully dressed) competitors from all around the world.

Who owns Antarctica?
Who owns Antarctica?
No one - it doesn't have a government. The Antarctica Treaty, signed by 46 countries, requires that the continent is used only for peaceful scientific research. Antarctica is very dry, cold, and windy, and about 98 per cent of its land surface is covered by ice. Very few plants grow there except mosses, lichens, and seaweed.
Which is the largest continent?
Which is the largest continent?
Asia- it covers one-third of the total land area of the Earth. North to south it extends from the Arctic Circle to just south of the Equator and at its widest point it measures 8,500 km (5,300 miles). Four billion people - three out of every five of the world's population - live in Asia.
Where does Europe end?
Where does Europe end?
That's a bit of a tricky one. Europe isn't a continent on its own but is attached to the western end of Asia. It is usually said to end at the Ural and Caucasus Mountains in Russia. Europe is the second smallest continent (only Australia is smaller). It occupies just 7 per cent of the Earth's surface, but contains 25 per cent of the world's population. There are 47 countries.
Why do planes fly above clouds?
Why do planes fly above clouds?
Aeroplanes are powered, heavier-than-air aircraft with fixed
wings. Most planes are flown above cloud level because there is not as much air
resistance higher up in the atmosphere, so they use less fuel. There is also less turbulence above clouds, meaning passengers don't get thrown about so much and there is less demand for sick bags!
"RECORD BREAKER"
The largest passenger aircraft is the Airbus A380. It has a wingspan of 79.8 m (261.8 ft) and can carry 853 passengers.
Can a car run on chocolate?
Can a car run on chocolate?
It may sound ridiculous, but it's true. In 2007, two British environmentalists drove a car 7,200 km (4.500 miles) from British to Timbuktu in Mali, Africa, powered by 4,000 kg (8,800 lbs) of chocolate converted into a biofual.
