Amazon Basin, satellite image
Amazon Basin. Satellite image of the Amazon Basin (highlighted area) in northern South America. North is at top. Water is blue, and land is colour-coded according to elevation above sea level: dark green (sea level), pink (2000 metres), and white (4500 metres). The Amazon Basin, over 7 million square kilometres in area, is the drainage basin of the Amazon River and is the largest in the world. The source of the Amazon lies high in the Andes mountain (down left). The waters drain eastward through the vast Amazon Rainforest, emerging at the mouth of the Amazon (upper right). In 2007, a new source for the Amazon was reported in southern Peru, which would make the Amazon the world's longest river. This image combines Shuttle Radar Topography Data and HydroSHEDS river data.

Satellite view of Southern Africa
Stunning view of South Africa. The arid, rugged Great Karoo runs along the southern coast where the Indian and Atlantic Oceans meet. From an indigenous word meaning dry thirst land, the Great Karoo's mountains and plains are home to a rich variety of plants and animals, including some of South Africa's most endangered species. The tan folds of the Nuweveld Mountain Range separate the Great Karoo in the south from the Northern Karoo in the north.
The brown and orange landscape that surrounds South Africa's northwestern borders is the Kalahari Desert, a vast sand basin marked by dunes and dry savannah vegetation. The southern edge of the desert is defined by the Orange River, which also forms South Africa's northwestern border with Namibia. In center and east South Africa, the ragged northern border is formed by the Molopo/Limpopo River.
Within South Africa is the enclave, Lesotho. This tiny mountainous country covers an area of 30, 355 square kilometers, slightly smaller than the state of Maryland. Northeast of Lesotho is the smaller country, Swaziland, with an area of 17, 363 square kilometers. Along the top of the image, from left to right, are Namibia, Botswana, Zimbabwe, and Mozambique.
