Cocos Island: Landforms
-
Description
-
The Cocos Island originated as a chain of islands, similar to the Galapagos Islands. The Cocos ridge is ~1000km long, ~200km wide, and has elevations no higher than 1000meters. Which makes it a very low elevation landform beneath the pacific ocean. Its north-east trend of 45 degrees is similar to the strike of the Middle America Trench, along which it is being subducted off Costa Rica and Panama continental plates. The island landform likely formed from a submarine volcano with a max elevation of 634 meters. The strata is composed of solid lava, which has soils that are now highly acidic and fragile.
