The Earth From the Air

Product Information

Although the temperature may be −60°C (−76°F; 210K) at the tropopause, the top of the stratosphere is much warmer, and may be near 0°C. Atmospheric effects become noticeable during atmospheric reentry of spacecraft at an altitude of around 120km (75mi). The lower part of the thermosphere, from 80 to 550 kilometres (50 to 342mi) above Earth's surface, contains the ionosphere. Photosynthesis is the chemical process when carbon dioxide and water react together, in the presence of light and chlorophyll , to produce glucose and oxygen.

However, the atmosphere is more accurately modeled with a customized equation for each layer that takes gradients of temperature, molecular composition, solar radiation and gravity into account. Because the Sun is close to the horizon, the Sun's rays pass through more atmosphere than normal before reaching your eye.Earth from the Air – A Photographic Portrait of Our Planet, by celebrated French aerial photographer Yann Arthus-Bertrand, is open until April 2004. In the stratosphere, starting above about 20km, the temperature increases with height, due to heating within the ozone layer caused by the capture of significant ultraviolet radiation from the Sun by the dioxygen and ozone gas in this region. He thus discovered a new passion for photography and the beauty of landscapes when observed from above in hot air balloons. Through twelve chapters with thoughtful introductions by several noted authors, The Earth from the Air - 365 New Days addresses the present and future health of the planet: agriculture, biodiversity, sustainable development, energy, foests, fresh water seas and oceans and global warming.

Air pollution is the introduction into the atmosphere of chemicals, particulate matter or biological materials that cause harm or discomfort to organisms.The troposphere is denser than all its overlying layers because a larger atmospheric weight sits on top of the troposphere and causes it to be most severely compressed. The atmospheric pressure at the top of the stratosphere is roughly 1/1000 the pressure at sea level. We came upon it by chance having made a trip into the city while we were attending a bonfire boating rally at the engine arm near Smethwick. Main article: Troposphere A picture of Earth's troposphere with its different cloud types of low to high altitudes casting shadows. It contains the ozone layer, which is the part of Earth's atmosphere that contains relatively high concentrations of that gas.
