Continents
A Journey around the World
Continents are continuous expanses of land that are clearly separated from each other by oceans.
The land masses are divided into seven continents:
North America, South America, Africa, Europe, Asia, Australia and Antarctica.
These continents are constantly moving.
About 260 million years ago, there was a huge continent which united all large plates of the Earth’s crust.
On this enormous continent called Pangaea, the time of the dinosaurs started about 230 million years ago.
Pangaea began to break up. Two land masses formed called Laurasia in the north and Gondwana in the south.
150 to 70 million years ago, Laurasia and Gondwana broke up further into individual land areas in which today’s continents can already be recognised.
Back then, these continents were much closer together.
So new oceans formed in the spaces in between them,

Product Piracy
Counterfeiting takes place in almost all economic sectors – textiles, watches, car parts, machine parts, tools, accessories, software and medicines. Some counterfeits are easy to recognise, others are so well-executed that even experts have difficulty distinguishing between original and imitation. This DVD covers the development of a product from idea to manufacture. Once a product has become a trademark, product pirates appear on the scene.
Air Traffic
Being able to fly has been a dream of humanity from time immemorial. But it does not even date back a century that people actually started being able to travel through the air. Since the 1960s, the number of flight passengers has been constantly increasing. Thus, the airspace is no longer dominated by birds but by man-made flying objects.
Youth Movement
Dancing until your feet hurt: Here, at the meeting on the Hoher Meissner near Kassel, 3,500 participants from Boy Scout associations, youth and Wandervogel groups from all over the German-speaking region have gathered. They want to celebrate, simply get to know each other and commemorate a historic anniversary.
