The life-cycle of the Solar System

The formation of the Sun and the planets started with the contraction of a dust cloud about 4.5 billion years ago.

Continents and oceans

Dry land on the surface of Earth is divided into continents which are separated by oceans.

Deep-sea hydrothermal vents

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

Earth

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

Fjord

A fjord is a long, narrow inlet with steep sides, created in a valley carved by glacial activity.

Topography of the Earth

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

Archaeopteryx

The archaeopteryx shows characteristics of both birds and reptiles. It is probably the ancestor of birds.

Carboniferous flora and fauna

This animation presents some animals and plants that lived between the Devonian and Permian periods (358–299 million years ago).

Deinonychus

Deinonychus antirrhopus, the 'terrible claw', was a carnivorous dromaeosaurid dinosaur.

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.

Glacier (basic)

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

Ichthyosaur

Fish-like marine dinosaurs which resembled dolphins; a good example of convergent evolution.

Ichthyostega

A prehistoric amphibian and an early representative of the Tetrapods, which became extinct 360 million years ago.

Pteranodon longiceps

A prehistoric flying reptile, similar to birds. However, there is no direct evolutionary link between the two.

Stegosaurus

A type of prehistoric reptile having bony plates on its back, which aided thermoregulation.

Tiktaalik

A transitional form between fish and tetrapods, or four-limbed vertebrates.

Triceratops

A type of herbivorous dinosaur easily recognisable by its large frill and three horns which lived in the Cretaceous period.

Trilobites

The ancestors of Arachnida and Crustacea belonged to the class Trilobita.

Ammonites

An extinct group of Cephalopoda, with solid external skeletons. They are excellent index fossils.
