Continents And The World !!

Continents fit together like pieces of a vast jigsaw. At one time (220 million years ago) all the continents were part of one supercontinent, which we now call Pangea. The land is made up of huge blocks which float on a sea of lava (molten rock). Slowly Pangea broke up and the continents drifted away from each other. They are still moving…

The biggest continent in the world is Asia. It is nearly five times larger than Australia, the smallest continent. Africa and Asia together account for just over half of all the land in the world.
The Atlantic Ocean is getting wider. North America is drifting away from Europe but only very slowly at 1cm (0.39in) in a year
The top 109 highest mountains in the world are all in Asia and 96 of them are in the Himalayas.
Mount Everest is the highest mountain of land. It is 8,848m (29,030ft) high. That is 20 times high as the Sears Tower in Chicago. If an office block was as high as Mount Everest it would have 2,200 storeys! (If you jumped off Mount Everest it would take you two minutes and 43 seconds to hit the ground.)
The first people to climb the top of Mount Everest were Edmund Hillary, a New Zealand mountaineer, and Sherpa Tenzing on 29th May, 1953.
SNOW AT THE EQUATOR
Mount Kenya is on the Equator, but its peak, 5,199m (17,058ft) above sea level, is always covered in snow.
As you climb a mountain, the temperature drops and the climate changes as if are going to the North or South Pole. If you climbed Mount Kenya you would leave the elephants and grassland at sea level, climb through tropical rainforest at around 1,650m (5,413ft), them through bamboo and heathland (watch out for leopards out here), before reaching alpine grassland towards the summit.
Mount Snowdon in Wales, was once as high as the mountains of the Alps (over 5,000m/16,405ft) but ice, wind, rain and snow have gradually worn it down to it present height of 1,085m (3,560ft).
Huge footprints have been found in the snow of the Himalayas and some people claim to have seen a monster, half person, half monkey, but no-one has ever captured such a creature. The most likely explanation is that the prints were made by the huge Moon bear.

The lowest dry land in the world is the shore of the Dead Sea between Israel and Jordan. It is 400m (1,312ft) below sea level. If there was a flight of stairs to take you back up to sea level you would have to climb 2,000 steps. Try climbing your own stairs that number of times and you will soon see how tiring it gets!
The Largest Cave

The largest cave in the world is the Sarawak Chamber in Sarawak, Malaysia. Its floor area is 210,000 sq. m (2,260,440ft), about the same size as three soccer pitches put together. Its roof is at least 70m (230ft) high, about as high as a 23 storey building.
The longest system of caves is in Kentucky in the United States. You can walk under the ground here along passages and through caves for over 530km (329 miles), that is the same distance as walking from Soughtampton to Carlisle – the whole lenght of England.
Ayer’s Rock in central Australia is one big chunk of rock 335m (1,099ft) high. It is much larger than all the other boulders in the surrounding desert, but not as large as Mount Augustus in Western Australia, another big rock, 1,105m (3,625ft) high.
The oldest rocks in the world are in Western Australia. They date from 4,300 million years ago, only 300 million years after the Earth was formed.
