Central America is a region at the center of the two of the American continents. It fully lies in a tropical climate and has savanna, rainforest, and mountainous regions. Geographically, it represents the southernmost part of the North American continent and it contains an isthmus that connects North America to South America. Panama is the border between the two continents. At its narrowest point, the isthmus stretches only 30 miles (50 km) wide.
The mainland portion of the region consists of seven different countries, but 13 nations in the Caribbean are also normally counted as a part of Central America. Central America shares borders with Mexico to the north, the Pacific Ocean to the west, Colombia to the south and the Caribbean Sea to the east.
