Ghana (West Africa) and Jamaica (Caribbean) are both tropical but differ fundamentally in scale, structure, and origin.
| Feature | Ghana | Jamaica |
|---|---|---|
| Area | 238,533 km² (92,098 mi²) | 10,991 km² (4,244 mi²) — 1/22nd Ghana |
| Topography | Mostly low plains; dissected plateau (Ashanti); hills N/E (Akwapim-Togo range). Highest: Mount Afadja (885 m) | Mountainous interior (Blue Mtns). Highest: Blue Mountain Peak (2,256 m) — 2.5× Ghana's max |
| Coastline | 539 km (Gulf of Guinea) — sandy, lagoons, estuaries | 1,022 km — indented, harbors, coral reefs, cays |
| Geology | Precambrian shield (Birimian), Paleozoic sediments, Volta Basin | Cretaceous limestone, Eocene volcanics (Blue Mtns), alluvial plains |
| Climate Zones | Tropical wet-dry (N) → Tropical wet (SW coast). Two rainy seasons. | Tropical wet (windward NE), Tropical wet-dry (leeward S). Orographic rain. |
| Rivers | Volta (largest reservoir: Lake Volta, 8,500 km²), Pra, Ankobra, Tano | Short, steep: Rio Grande, Black River, Martha Brae. No large lakes. |
| Vegetation | Guinean forest-savanna mosaic; rainforest SW; savanna N | Tropical rainforest (windward), dry forest (leeward), mangroves, montane cloud forest |
| Biodiversity | High (forest elephants, primates, 750+ birds) | High endemism (birds, reptiles, plants); no native land mammals except bats |
| Natural Hazards | Floods, droughts, coastal erosion | Hurricanes, earthquakes, landslides, tsunami risk |
Core difference: Ghana = ancient continental shield, vast, river-dominated. Jamaica = young oceanic arc, compact, mountain-dominated, island biogeography.
