DescriptionSaint Helena Island.jpg |
English: This astronaut photograph shows the island’s sharp peaks and deep ravines; the rugged topography results from erosion of the volcanic rocks that make up the island. The change in elevation from the coast to the interior creates a climate gradient. The higher, wetter centre is covered with green vegetation, whereas the lower coastal areas are drier and hotter, with little vegetation cover.
Français : Photo de l'île de Sainte Hélène prise par un astronaute de la NASA. On peut voir les pics élevés de l'île et ses ravines profondes. Cette topographie accidentée résulte de l'action de l'érosion sur les roches volcaniques dont l'île est constituée. Le changement d'élévation entre la périphérie et le centre de l'île créé un gradient climatique: le sommet est plus frais et humide, il est couvert de végétation. Les côtes, plus chaudes et sèches, laissent apparaitre la roche nue.
