The Earth from the Air: Yann Arthus-Bertrand

Product Information

Different molecules absorb different wavelengths of radiation. For example, O 2 and O 3 absorb almost all radiation with wavelengths shorter than 300 nanometres. Water (H 2O) absorbs at many wavelengths above 700nm. When a molecule absorbs a photon, it increases the energy of the molecule. This heats the atmosphere, but the atmosphere also cools by emitting radiation, as discussed below. The first major era of the Phanerozoic is called the Paleozoic, and the Cambrian is the first period of the Paleozoic era. “The Cambrian Explosion of Life” was the rapid appearance of almost all forms of life. Paleontologists and geologists have studied fossils of archaea, bacteria, algae, fungi, plants, and animals that lived during the Cambrian period. The Cambrian was followed by the Ordovician, Silurian, Devonian, Carboniferous, and Permian periods.

Earth From The Air has been touring the country since its debut at the British Natural History Museum in 2002. Earth’s atmosphere is a blanket of gases enveloping Earth and retained by our planet’s gravity. Atmospheric gases include nitrogen, water vapor, oxygen, and carbon dioxide. A) Mole fraction is sometimes referred to as volume fraction; these are identical for an ideal gas only. Earth is the third planet from the sun, after Mercury and Venus, and before Mars. It is about 150 million kilometers (about 93 million miles) from the sun. This distance, called an astronomical unit (AU), is a standard unit of measurement in astronomy. Earth is one AU from the sun. The planet Jupiter is about 5.2 AU from the sun—about 778 million kilometers (483.5 million miles). Arthus-Bertrand's mission was to create a photographic record of the natural world at the start of a new millennium. Taken from all over the planet, the 160 photographs chosen for the exhibition tell a story about our changing planet and the need for sustainable development.Earth from the Air is a popular collection of environmental photographs taken from the air by Yann Arthus-Bertrand. They have been published in a number of books together with text describing environmental concerns related to the photographs. Air pressure actually decreases exponentially with altitude, dropping by half every 5.6km (18,000ft) or by a factor of 1/ e (0.368) every 7.64km (25,100ft), (this is called the scale height) -- for altitudes out to around 70km (43mi; 230,000ft). 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. At heights over 100km, an atmosphere may no longer be well mixed. Then each chemical species has its own scale height. The end of Earth will come with the end of the sun. In a few billion years, the sun will no longer be able to sustain the nuclear reactions that keep its mass and luminosity consistent. First, the sun will lose more than a quarter of its mass, which will loosen its gravitational hold on Earth. Earth’s orbit will widen to about 1.7 AU. But the sun will also gain volume, expanding to about 250 times its current size. The sun in this red giant phase will drag Earth into its own fiery atmosphere, destroying the planet.

From the age of 17 he became involved in the movie industry. He gave up the movie industry in 1967 to run the Château de Saint Augustin wildlife park in Château sur Allier (centre of France). He then left the country with his wife Anne when he was 30 (1976) to live in Kenya in the Massai Mara national park. He lived amongst the Massai tribe for 3 years to study the behaviour of a lions’ family and took daily pictures of them during those years. He thus discovered a new passion for photography and the beauty of landscapes when observed from above in hot air balloons. He understood the power of a picture and how to communicate using this means. The water cycle involves three main phases, related to the three states of water: solid, liquid, and gas. Ice, or solid water, is most common near the poles and at high altitudes. Ice sheets and glaciers hold the most solid water.homosphere – AMS Glossary". Amsglossary.allenpress.com.

Since I also have the original "The Earth From The Air", which has the same author and features many of the same photos, I will also be comparing these two books with each other. Compressed air is air kept at a consistent pressure, such as air pressure at sea level. Airplanes are usually pressurized at ground level so passengers can breathe without canisters of air. is below 100km (62mi; 330,000ft), the Kármán line. By international convention, this marks the beginning of space where human travelers are considered astronauts. The constant re-arrangement of continents by plate tectonics influences the long-term evolution of the atmosphere by transferring carbon dioxide to and from large continental carbonate stores. Free oxygen did not exist in the atmosphere until about 2.4 billion years ago during the Great Oxygenation Event and its appearance is indicated by the end of the banded iron formations.

Ancient sediments in the Gabon dating from between about 2.15 and 2.08 billion years ago provide a record of Earth's dynamic oxygenation evolution. These fluctuations in oxygenation were likely driven by the Lomagundi carbon isotope excursion. [53] Third atmosphere Oxygen content of the atmosphere over the last billion years [54] [55] Often, compressed air is kept at a pressure higher than normal air pressure. Scuba divers use compressed air to breathe under water. The canisters of air allow divers to inhale through a tube and exhale into the water. Main article: Mesosphere Afterglow of the troposphere (orange), the stratosphere (blue) and the mesosphere (dark) at which atmospheric entry begins, leaving smoke trails, such as in this case of a spacecraft reentry. The exosphere is the outermost layer of Earth's atmosphere (though it is so tenuous that some scientists consider it to be part of interplanetary space rather than part of the atmosphere). It extends from the thermopause (also known as the "exobase") at the top of the thermosphere to a poorly defined boundary with the solar wind and interplanetary medium. The altitude of the exobase varies from about 500 kilometres (310mi; 1,600,000ft) to about 1,000 kilometres (620mi) in times of higher incoming solar radiation. [22]As organisms die and decompose, they release carbon into the ocean, soil, or atmosphere. Plants and other autotrophs use this carbon for photosynthesis, starting the carbon cycle again.

The atmosphere of Earth is the layer of gases, known collectively as air, retained by Earth's gravity that surrounds the planet and forms its planetary atmosphere. The atmosphere of Earth creates pressure, absorbs most meteoroids and ultraviolet solar radiation, warms the surface through heat retention ( greenhouse effect), allowing life and liquid water to exist on the Earth's surface, and reduces temperature extremes between day and night (the diurnal temperature variation). Most of Earth’s history took place in the Pre cambrian, which began when Earth was cooling and ended about 542 million years ago. Life began in the Precambrian, in the forms of bacteria and other single-celled organisms. Fossils from the Precambrian are rare and difficult to study. The Precambrian supereon is usually broken into three eons: the Hadean, the Archaean, and the Proterozoic.
