Caption: Dust storm, Chad. Satellite image of the Bodele Depression, northern Chad. This is the dustiest place on Earth. The land surface is composed of very fine grained sedimentary rock known as diatomite. Strong winds blow huge amounts of dust (centre of image) up to 47 kilometers high into the atmosphere where it is transported east out into the Atlantic Ocean. Dust from here and the Sahara desert can be transported as far as North and South America. Airborne dust and other aerosols cause climate change by reflecting sunlight and encouraging cloud formation. Image taken by NASA's Aqua satellite on 18 November 2004.
