Madagascar is a long island east of Mozambique, separated from the mainland by the Mozambique Channel. A regional image shows the central highlands and a relatively narrow eastern coastal strip; many western rivers have more room to develop across lower terrain.
Checking the location
Locate the whole island before examining a smaller crop. A red soil patch or eroded slope is not unique to Madagascar, and green cover does not identify a forest type without more information. Trace a river from the highlands toward the coast and compare how the drainage differs on the two sides.
