Geology da siffofin ƙasa

Jamaica (which is a very mountainous country) and the other islands of the Antilles evolved from an arc of ancient volcanoes that rose from the sea millions of years ago. During periods of submersion, thick layers of limestone were laid down over the old igneous and metamorphic rock. In many places, the limestone is thousands of feet  thick. The country can be divided into three landform regions: the eastern mountains, the central valleys and plateaus, and the coastal plains.

A yammacin duwatsun akwai tsaunuka masu tsawo na Cockpit Country, daya daga cikin misalai masu ban mamaki na duniya na yanayin karst.

The Cockpit Country is pockmarked with steep-sided hollows, as much as 15 metres (49 ft) deep in places, which are separated by conical hills and ridges. On the north, the main defining feature is the fault-based "Escarpment", a long ridge that extends from Flagstaff in the west, through Windsor in the centre, to Campbells and the start of the Barbecue Bottom Road (B10). The Barbecue Bottom Road, which runs north–south, high along the side of a deep, fault-based valley in the east, is the only drivable route across the Cockpit Country. However, there are two old, historical trails that cross further west, the Troy Trail, and the Quick Step Trail, both of which are seldom used As of 2006 and difficult to find. In the southwest, near Quick Step, is the district known as the "Land of Look Behind," so named because Spanish horsemen venturing into this region of hostile runaway slaves were said to have ridden two to a mount, one rider facing to the rear to keep a precautionary watch. Where the ridges between sinkholes in the plateau area have dissolved, flat-bottomed basins or valleys have been formed that are filled with terra rosa soils, some of the most productive on the island. The largest basin is the Vale of Clarendon, 80 kilometres (50 mi) long and 32 kilometres (20 mi) wide. Queen of Spains Valley, Nassau Valley, and Cave Valley were formed by the same process.
