Description:
With no land for a thousand miles in any direction, there is nothing to interrupt the build up of the waves. However, this is not a surfers paradise. The island rises steeply from the floor of the ocean and the massive waves generate a fierce undertow. Residents know not to try and visitors are warned not to swim off the beaches.

Description:
First there were just the birds, then man arrived and with him rats from the ships. They increased and became a nuisance, so cats were brought in to control the rats. The cats found a much easier prey in the millions of birds which nested on the island, many of them on the open ground.
A large population of feral cats has built up, the seabird population has crashed and the latest talk is of culling the cats.

Description:
This islet off the coast of Ascension demonstrates what the bird populations must have been like, over the whole island, before the arrival of the cats.

Description:
Ascension Island is a recently formed part of the Earth's surface. It emerged from the Mid Atlantic Ridge, where the Earth's crust is moving apart and is marked by a line of volcanic activity, stretching from Iceland to Tristan da Cunha. Ascension is classed as "dormant".
Ascension has an arid climate and there is little vegetation, although every few years it enjoys more humid conditions and acquires a green cover.

Description:
Indirectly, turtles demonstrate the existence of continetal drift- the movement of the plates that make up the Earth's crust. Millions of years ago, turtles used the islands close to their marine habitat as a safe place to lay their eggs. As the floor of the Atlantic spread, this involved a longer and longer journey as the Atlantic increased in width. Today the turtles have a journey of thousands of miles and demonstrate a considerable feat of navigation.
