Geyser

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

Deep-sea hydrothermal vents

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

Faulting (basic)

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

Folding (basic)

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

Folding (intermediate)

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

Topography of the Earth

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

Tornadoes

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

Carbon cycle
