The Andes Mountains, Peru
We have here an image of part the Andes Mountains in Peru, a country in western South America covering 1,285,220 km² (496,193 sq mi).
The Andes mountains run parallel to the Pacific Ocean, dividing the country into three geographic regions, which are exemplified in this image:
The costa (coast), to the west, is a narrow plain, largely arid except for valleys created by seasonal rivers. In our image the costa appears light tan in color.
The sierra (highlands) is the region of the Andes Mountains. The higher altitudes in our image are capped by snow, whereas other areas are dark brown.
The third and final region is the selva (jungle), a wide expanse of flat terrain covered by the Amazon rainforest that extends east. Almost 60% of the country’s area is located within this region. A patch of the selva is visible in the upper right corner of the image, as are some rivers, their waters brown with sediments.
Most Peruvian rivers originate in the Andes and drain into one of three basins: the Pacific Ocean, tributaries of the Amazon River and Lake Titicaca.
