Explanation:

Central America is a region that lies between North America and South America, being the land mass that connects the two large continents. It stretches north from Belize and Guatemala to Panama on the south.

The regions's topography can be described very simply. The central part of the region is a mountainous core. The Pacific coast is dominated by small plains, while the Caribbean coast is dominated by lowlands.

The mountain range is of volcanic origin, as on both sides of the region there are subduction zones. As the volcanoes were rising above the surface, they created dominant landforms that roughly divides the region in eastern and western half.
