The planet is a dynamic planet that has actually been constantly changing since that came right into being. Thrust by powerful convection cells within the Earth, continents drift, giving rise come earthquakes, volcanoes and mountain ranges. Organisms life on land, in the water or in the air must adapt come these changes and, in turn, have an influence on your habitat and also system Earth. That is this interdependence that renders our planet distinctive in the solar system.

In addition, the planet is likewise connected to the cosmos neighboring it. Every day, cosmic rock product hits the earth – mostly just the size of a speck that dust, yet occasionally, meteorites with a diameter of several kilometres deserve to hit the Earth and pose a hazard for life ~ above the planet. These interconnected processes are studied by scientists at the Museum. What cd driver the dynamics of planet Earth? exactly how are individual procedures interconnected? These room the concerns the exhibition System planet is trying come answer.

Multimedia Globe

A three-metre-high globe in the centre of the hall shows animations and film assignment on subject such as plate tectonics, volcanism, the impact of asteroids and meteorites, the development of mountain ranges and the atmosphere. This topics are taken up and discussed more extensively in themed archipelago in the room v exhibits, texts and also animations. The world itself likewise gives an insight into the multi-layered structure and also material composition of the Earth.


Plate tectonic

Plate tectonic motion alters the circulation of land and sea ~ above the Earth. Landmasses previously separated by water may link up, while other huge continents are broke up into several smaller ones. Once previously different landmasses connect, brand-new opportunities arise for plants and animals come spread, together the land bridge of Panama demonstrates, which has been allowing the exchange of wildlife between North and also South America for approximately 3 million years. Gigantic armadillos, giant sloths and also anteater travelled from the southern to the North, stable in phibìc America, whereas the sabre-tooth cat Smilodon took the opposite course and settled in south America.




Volcanoes space the Earth’s organic safety valves. Magma native the mantle or lower crust rises with cracks in the crust come the surface, extruding together lava or a mix that ash and also gases. The around 600 currently energetic volcanoes are largely situated in ~ the leaf of tectonic plates the move versus each other. Over there is additionally volcanic task in what is known as hotspots within continental plates.

Hawaii is more than likely the best known example of volcano hotspot activity. The many common form of lava is fast-flowing basaltic lava that creates subterranean cave systems ~ above its way to the sea. Once the lava circulation has stopped, this caves end up being the habitat the highly adapted animals, such together cave-dwelling cicadas. Together the formation of caves is very dynamic, over there is a matching evolution the different species – a prime study example for advancement researchers.



Horses, grass and climate

The advancement of horses goes hand in hand with the development of vegetation over the critical 50 million years. The precursors of the contemporary horse were barely the size of a dachshund. They lived in dense rain woodlands which, because of favourable climatic conditions covered Europe ideal up to the north. Finds in Germany from that period comprise over all primeval horses from the Messel.

True grasses developed in the late Cretaceous, yet could hardly expand due to the heat climate. Only when it cooled down and the carbon dioxide contents in the atmosphere dropped did the forest recede and also grassland began to spread. In ~ the exact same time, horses started to move from leaves as a food resource to grass. Citizens of the steppe, they thrived larger. Steppe horses prevented bushes indigenous invading the grassland and helped its additional spread. Scientists think that this, in turn, had an affect on the climate, as grassland sequestrated organic carbon and also prevented carbon dioxide from being released into the atmosphere, thus increasing the cooling process.
