Major Physical Features of Central America & the Caribbean
The region's geography is defined by a dramatic mix of seas, mountains, islands, and reefs:
Marine Basins
- Caribbean Sea – 2.7M km² semi-enclosed sea; avg depth 2,200m. Borders Central America, South America, and the Antilles.
- Gulf of Mexico – 1.6M km²; avg depth 1,500m. Borders US, Mexico, Cuba. Connected to Caribbean via Yucatán Channel.
Island Arcs: The Antilles
- Greater Antilles: Cuba, Jamaica, Hispaniola (Haiti/D.R.), Puerto Rico – large, mountainous, diverse.
- Lesser Antilles: Volcanic arc (Windward/Leeward Islands) + limestone islands (Barbados, Antigua). Active volcanism (Soufrière, Montserrat).
Central American Isthmus
Narrow land bridge (7 countries) with volcanic mountain spine (Sierra Madre continuation) and narrow coastal plains. Key volcanoes: Tajumulco (Guatemala, 4,220m), Atitlán, Popocatépetl (Mexico).
Mountain Ranges
- Sierra Madre – Mexico through Central America.
- Cordillera Isabelia – Dominican Republic.

Coastal Plains & Wetlands
Sediment-rich lowlands on both coasts—mangroves, estuaries, agricultural zones (banana, sugarcane, rice).
Coral Reefs
Mesoamerican Barrier Reef – 1,000+ km off Belize, Guatemala, Honduras, Mexico. 2nd largest globally. Critical biodiversity hotspot.
This physical template drives the region's climate zones, ecosystems, natural hazards, and human settlement patterns.
