What are the three major landform regions of central America?

1. The Caribbean Lowlands: This region consists of coastal plains, mangrove swamps, and lagoons that extend along the Caribbean coast. It is generally low-lying and has a tropical climate.

2. The Central Highlands: This region is dominated by rugged mountain ranges, including the Sierra Madre de Oaxaca, the Sierra Madre del Sur, and the Cordillera Central. It has a more temperate climate and is home to many volcanoes.

3. The Pacific Lowlands: This region consists of coastal plains and rolling hills that extend along the Pacific coast. It is generally drier than the other two regions and has a more tropical climate.
