Terms of physical geography

This animation demonstrates the most important relief features, surface waters and their relevant symbols.

The water cycle (basic)

Water on Earth is in a continuous state of change. The water cycle includes processes such as evaporation, precipitation, melting and freezing.

The water cycle (intermediate)

Water on Earth is in a continuous state of change. The water cycle includes processes such as evaporation, precipitation, melting and freezing.

Aeolian landforms in deserts

Wind, as an external force, plays an important role in shaping deserts.

Aeolian landforms on coasts and steppes

Wind, as an external force, plays an important role in shaping coastal areas and steppes.

Flood defence system

The protective embankment, or, in case of minor floods, the summer dyke ensures the protection against flood damage.

Glacier (intermediate)

A glacier is a large body of ice that forms from snow, and is in constant, slow motion.

How do seas shape the Earth's surface?

Seawater, as an external force, plays an important role in shaping coastlines.

Hydroelectric power plant (Hoover Dam, USA)

The huge dam built on the Colorado river in the US was named after a former American President.

Operation of river locks

River locks make rivers with great level differences safe for boating.

The development of lakes

Standing bodies of water can form in depressions on the surface by both endogenic and exogenic forces, as well as by human activity.

The Zuiderzee Works and the Delta Works (Netherlands)

Remarkable civil engineering works to continue the Netherland's centuries-long fight against the sea.

Topography of the Earth

The animation presents the largest mountains, plains, rivers, lakes and deserts of the Earth.

Vandens tarša

Pagrindiniai vandens taršos šaltiniai yra pramonė, žemės ūkis ir miesto teritorijos.
