Coasts
Shapes and Formation
The border area of the ecosystems of land and sea, which influence each other, is referred to as coast. Depending on their shapes, the coasts can be few to several kilometres wide and are constantly changed by surf, tides, sea level fluctuations and coastal currents in the zone of influence. These processes have both destructive and constructive effects and result in different types of coasts.

Ceramic
Ceramics are indispensable in our everyday lives. We eat from ceramic plates, drink from ceramic cups, use tiled ceramic bathrooms. But how is ceramic manufactured? The film reveals the secrets of this fascinating material! We get to know more about the beginnings of ceramic in the Old World of Egypt and Mesopotamia, about Greece, China and Rome. We gain interesting insights into the valuable earthenware and are also shown the exquisite further development of the "white gold". Today this versatile material is irreplaceable in industry, too. Whether in space or as an easily compatible substitute in medicine, ceramic is applied in many places.
