The average mass of the atmosphere is about 5 quadrillion (5 ×10 15) tonnes or 1/1,200,000 the mass of Earth. Physical properties Comparison of the 1962 US Standard Atmosphere graph of geometric altitude against air density, pressure, the speed of sound and temperature with approximate altitudes of various objects. The pictures cover every corner of ever continent, from icy arctic floes to tropical forests, from the deserts of north Africa to the vertiginous peaks of Nepal.

The atoms and molecules are so far apart that they can travel hundreds of kilometres without colliding with one another. However, the temperature has a more complicated profile with altitude, and may remain relatively constant or even increase with altitude in some regions (see the temperature section, below).Yann Arthus-Bertrand’s photographic portrait of our planet, Earth from the Air, has been shown in 52 cities since its launch in 1999. Temperatures drop with increasing altitude to the mesopause that marks the top of this middle layer of the atmosphere. Several layers can be distinguished in the atmosphere, based on characteristics such as temperature and composition. This includes the tape, airbags, bubblewrap and biofill (commonly known to as loosefill, international only), and of course the boxes and catalogues themselves.

This updated edition of the internationally acclaimed original features an updated text and over 100 breathtaking new photographs. The geological record however shows a continuous relatively warm surface during the complete early temperature record of Earth – with the exception of one cold glacial phase about 2.

The following time span from 539 million years ago to the present day is the Phanerozoic Eon, during the earliest period of which, the Cambrian, oxygen-requiring metazoan life forms began to appear. Atmospheric effects become noticeable during atmospheric reentry of spacecraft at an altitude of around 120 km (75 mi). This daybook presents 365 entirely new, utterly dazzling images from master aerial photographer Yann Arthus-Bertrand. The troposphere is bounded above by the tropopause, a boundary marked in most places by a temperature inversion (i. New editorials by such renowned authors as Jane Goodall, Matthieu Ricard and Olivier Blond consider such perpetual issues as agriculture, climate and biodiversity, as well as the latest concerns – refugees, new technologies and environmental movements.

O 2 showed major variations until reaching a steady state of more than 15% by the end of the Precambrian.

Free oxygen molecules did not start to accumulate in the atmosphere until the rate of production of oxygen began to exceed the availability of reducing materials that removed oxygen.

e. a layer of relatively warm air above a colder one), and in others by a zone that is isothermal with height. The surface-based homosphere includes the troposphere, stratosphere, mesosphere, and the lowest part of the thermosphere, where the chemical composition of the atmosphere does not depend on molecular weight because the gases are mixed by turbulence. Earth is approximately 290 K (17 °C; 62 °F), so its radiation peaks near 10,000 nm, and is much too long to be visible to humans. Following the peak in vegetation, the drawdown of atmospheric CO 2 due to photosynthesis is apparent, particularly over the boreal forests. A classic of its kind, this book will heighten everyone's awareness of today's urgent ecological issues.Often taken from a low altitude, they reveal the imprint of human civilization on the face of the globe.
