Earth from space, satellite image
Earth from space. Satellite image showing North and South America as seen from 35, 000 kilometres above the Earth's surface. North is at top and the Moon is at upper right. Clouds (white) are seen, as are seas and oceans (blue). Land cover ranges from vegetation such as forests and grassy plains (green) to arid areas such as deserts, mountains, and scrublands (brown). This image combines data from the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument aboard NASA's Terra satellite and NOAA's Geostationary Operational Environmental Satellite (GOES).

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.
