Tectonic plates

Tectonic plates can move in relation to each other.


Tsunami waves are very high waves of immense destructive power.


Šajā animācijā iepazīsiet dažādus vulkānu izvirdumu veidus.

Characteristics of sound waves

This animation explains the most important characteristics of waves through sound waves.

Deep-sea hydrothermal vents

A hydrothermal vent is a fissure in the planet's surface through which geothermally heated water erupts.

Folding (intermediate)

Lateral compressive forces cause rocks to form folds. This is how fold mountains are formed.

Formation of stratovolcanoes

Stratovolcanoes consist of layers of volcanic ash, debris and lava.


A geyser is a spring characterised by intermittent discharge of water and steam.


Hotspots are areas of the Earth´s crust where magma often rises to the surface and causes volcanic activity.

Seafloor map

The boundaries of tectonic plates can be seen on the seafloor.

The Doppler effect

It is a well-known phenomenon that the sound of an approaching sound source is higher than that of a receding one.

The structure of Earth (intermediate)

The Earth is composed of several spherical layers.

Topography of the Earth

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


Short-lived but extremely powerful tornadoes can cause a great deal of damage.

Types of waves

Waves play an extremely important role in many areas of our lives.

Continental drift on a geological timescale

The Earth's continents have been in constant motion during the history of the planet.


The Earth is a rocky planet with a solid crust and oxygen in its atmosphere.

Faulting (intermediate)

Vertical forces can break up layers of rock into fault blocks, which then move vertically along the fracture planes.

Folding (advanced)

Lateral compressive forces cause rocks to form folds. This is how fold mountains are formed.
