This animation demonstrates different types of volcanic eruptions.
Icebergs are blocks of frozen freshwater floating in the sea.
Lightning is a sudden electrostatic discharge accompanied by a sound known as thunder.
Water on Earth is in a continuous state of change. The water cycle includes processes such as evaporation, precipitation, melting and freezing.
Tsunami waves are very high waves of immense destructive power.
The Great ocean conveyor is a planet-wide system of ocean currents, which has a great influence on the Earth´s climate.
Evaporating surface water forms clouds of various shapes from which water falls back to the surface as precipitation.
Hotspots are areas of the Earth´s crust where magma often rises to the surface and causes volcanic activity.
A hydrothermal vent is a fissure in the planet's surface through which geothermally heated water erupts.
Rivers play an important role in shaping the Earth's surface: they cause erosion as well as carrying and depositing sediment.
Physical properties, as well as the flora and fauna of the ocean change with depth.
Tectonic plates can move in relation to each other.
Seawater, as an external force, plays an important role in shaping coastlines.
An earthquake is one of the most devastating natural phenomena.
Wind, as an external force, plays an important role in shaping deserts.
In mountainous areas the climate, soil properties, the flora and fauna change depending on elevation.
Standing bodies of water can form in depressions on the surface by both endogenic and exogenic forces, as well as by human activity.
Short-lived but extremely powerful tornadoes can cause a great deal of damage.
Vertical forces can break up layers of rock into fault blocks, which then move vertically along the fracture planes.
This animation demonstrates the most important relief features, surface waters and their relevant symbols.
