Généralement de très petites tailles voire parfois microscopiques ils abattent cependant une somme de travail énorme dans la fragmentation de tous les détritus augmentant ainsi la capacité des déchets à se décomposer de façon naturelle. Cette décomposition résultant du passage des recycleurs va induire la formation de composés minéraux assimilables par les végétaux. Certains sont nécrophages et débarrassent le sols des cadavres, d’autres sont saprophage ou détritivores et se nourrissent des débris végétaux ou animaux, enfin certains sont coprophage c'est-à-dire qu’ils mangent les excréments.

Prehistoric World, Prehistoric Time, Photos Videos, Maps, Facts, Images, and More. History of the Earth. The history of the Earth concerns the development of the planet Earth from its formation to the present day.[1][2] Nearly all branches of natural science have contributed to the understanding of the main events of the Earth's past.
The age of Earth is approximately one-third of the age of the universe. An immense amount of biological and geological change has occurred in that time span. The first life forms appeared between 3.8 and 3.5 billion years ago. Geologic time scale. The geologic time scale (GTS) is a system of chronological measurement that relates stratigraphy to time, and is used by geologists, paleontologists, and other earth scientists to describe the timing and relationships between events that have occurred throughout Earth's history. The table of geologic time spans presented here agrees with the nomenclature, dates and standard color codes set forth by the International Commission on Stratigraphy. Evidence from radiometric dating indicates that the Earth is about 4.54 billion years old. The geology or deep time of Earth's past has been organized into various units according to events which took place in each period.
Different spans of time on the GTS are usually delimited by changes in the composition of strata which correspond to them, indicating major geological or paleontological events, such as mass extinctions. Geologic time scale. Online exhibits Geologic time scale Take a journey back through the history of the Earth — jump to a specific time period using the time scale below and examine ancient life, climates, and geography. You might wish to start in the Cenozoic Era (65.5 million years ago to the present) and work back through time, or start with Hadean time (4.6 to 4 billion years ago)* and journey forward to the present day — it's your choice.

You might wish to start in the Cenozoic Era (65 million years ago to the present) and work back through time, or start with Hadean time (4.5 to 3.8 billion years ago) and journey forward to the present day. No matter "when" you start, don't forget to stop along the way to learn about the stratigraphy, ancient life, fossil localities, and tectonics of the various time periods. Here are three links that can help to speed your journey: 1) Get helpful hints on navigating the Geology Wing. Prehistory. Prehistory (meaning "before history", or "before knowledge acquired by investigation", from the Latin word for "before," præ, and historia) is the span of time before recorded history or the invention of writing systems.
Prehistory refers to the period of human existence before the availability of those written records with which recorded history begins.[1] More broadly, it can refer to all the time preceding human existence and the invention of writing.

Geology. Ecology. Zoology. Les premiers résultats d’analyse de roc de Curiosity. Le Jet Propulsion Laboratory a affiché sur son site les premiers résultats d’analyse du roc Jake Matjevic. Ce roc avait fait l’objet d’une analyse par la Chemcam (analyse à distance suite a vaporisation de surface du roc par tir laser) les 21 et 24 septembre. Matjevic était le 30 ème roc à faire ainsi l’objet d’un tir Chemcam. Mais il a également fait l’objet, le 22 septembre, d’une analyse par le spectromètre à particules alpha monté au bout du bras télémanipulateur, dont c’était la première opération.
Les mesures ont indiqué du diopside, une variété de pyroxène caractéristique d’une roche ignée c'est-à-dire créée sous la croûte d’une planète par cristallisation d’un magma riche en eau sous pression élevée.
