Le jeu de 7 familles « La vie cachée des sols » - Biodiversité: La vie cachée des sols - Dossiers thématiques : Gessol Il s’agit des organismes du sol les plus petits, ils ne sont pas plus grands qu’un dixième de millimètre. Invisibles à l’œil nu, il faut un microscope pour les observer. Ces organismes transforment les débris végétaux, entretiennent de complexes interactions trophiques (les protozoaires mangent bactéries et protozoaires, les nématodes mangent bactéries, protozoaires, voire même d’autres nématodes) ou font des symbioses avec des organismes plus gros. Dans cette famille, on trouve des organismes unicellulaires, comme les bactéries et les protozoaires (ciliés et amibes), et des organismes pluricellulaires : champignons, rotifères et nématodes (plus d’informations pages 70-71 de l’Atlas européen de la biodiversité des sols). Les bactéries sont très petites et très abondantes dans les sols : jusqu’à 1 milliard dans une petite cuillère à café de sol. haut de page
Mexico earthquake: New tremor halts rescue operations Image copyright EPA A strong tremor in southern Mexico temporarily suspended the search for survivors of this week's powerful earthquake in the capital, Mexico City. People ran into the streets as alarms sounded after the magnitude 6.1 quake hit the state of Oaxaca, some 520km (323 miles) south of Mexico City. Some buildings already damaged and a bridge collapsed in the state. Tuesday's quake left at least 305 dead. Hope is fading that more survivors can be rescued from the rubble. Saturday's earthquake struck near the city of Matias Romero at 07:53 local time (12:53 GMT) and was relatively shallow, with a depth of 9km, the US Geological Survey said. Mexico's disaster agency said it was an aftershock of the magnitude 8.1 earthquake that hit the state on 7 September, in which at least 90 people died. Media playback is unsupported on your device The tremor was mild in Mexico City but thousands of residents, many wearing pyjamas, ran into the streets when seismic alarms sounded.
Earthquake App That Warns You Minute Before Will Be Available Soon In a contemporary era, the advancement of technology will enable us with an Earthquake App which will be designed to deliver the people immediate warnings about the danger of earthquakes, conceivably providing worthful seconds to tuck away or mitigate injuries. Generally, this kind of Earthquake App is going to warn people that they might sense the items around them; even an apartment may start shaking since this app will have spotted the signals of an earthquake. There will also be some features in the program’s instruction that can make people ready for an earthquake by providing each detail on current earthquake, and get aid after that. Which Factors Lead An Earthquake To Happen? While people always have anxiety about the health of themselves and their families, unexpected natural disasters such as earthquakes are the most significant horrifying factors too. When 2 or more parts of the rock are rubbing against one another, they adhere together. Are Earthquakes Tough To Predict?

The moving story of plate tectonics | Science Today no-one doubts that the Earth’s surface is made up from a moving jigsaw of tectonic plates. Primary school children learn that South America was once connected to Africa, and that India’s collision with Asia pushed up the Himalayas. In hindsight plate tectonics seems obvious, and yet just 60 years ago the prevailing view was that continents were fixed in place. Back in 1912 Alfred Wegener, a German geophysicist, noticed that if Earth’s landmasses were pushed together their boundaries appeared to fit loosely together, leading him to hypothesise that continents slowly drift around the Earth. An article in the August issue of Geoscientist describes how Sir Edward Bullard and his colleagues at the University of Cambridge, wrote a computer program to move continents around the globe and find the best fit. The theory has revolutionised our view of Earth, and may even be one of the reasons why Earth is hospitable for life.
UK school seismology project | 'real science with real data' Real science with real data The school seismology project enables schools to detect signals from large earthquakes happening anywhere in the world. The sheer destructive power of earthquakes has always held a fascination for children. This project capitalises on this natural interest by making use of earthquakes and seismology as a unifying theme to teach a range of basic science concepts. Station lists and maps From the 200 or so seismometers in the British Isles, you can also view school seismometer stations around the world. Significant earthquakes Showing significant earthquakes from around the world that make the news or M7 and above; M3 earthquakes and above in and around the British Isles.

OUTILS référentiel badges réussite.pdf Learn About the Mexico 2017 Earthquake–and How Earthquakes Work Latest News On Tuesday, September 19, a magnitude 7.1 earthquake shook Mexico City, toppling buildings and crushing cars. There are now more than 200 dead. The earthquake hit about 100 miles away from Mexico City at 1:00 p.m. local time. (See heartbreaking photographs of the destruction.) More About Earthquakes Earthquakes, also called temblors, can be so tremendously destructive, it’s hard to imagine they occur by the thousands every day around the world, usually in the form of small tremors. Where Do Most Earthquakes Occur? Some 80 percent of all the planet's earthquakes occur along the rim of the Pacific Ocean, called the "Ring of Fire" because of the preponderance of volcanic activity there as well. These impacts are usually gradual and unnoticeable on the surface; however, immense stress can build up between plates. Earthquake Magnitude Ratings and Their Impacts Scientists assign a magnitude rating to earthquakes based on the strength and duration of their seismic waves.
Le séisme japonais a-t-il changé la durée du jour ? Nous relations l’an passé les calculs d’un géophysicien de la NASA : selon Richard Gross, le tremblement de Terre qui venait de frapper le Chili a fait augmenter la vitesse de rotation de la Terre, et donc diminuer la durée des jours… D’un point de vue théorique, tout changement de répartition de la masse sur la Terre modifie sa vitesse de rotation. Les masses étant redistribuées plus ou moins loin de l’axe de rotation de la Terre, sa vitesse de rotation varie. Cent microsecondes par jour. Cela dit, l’influence imputable aux séismes n’existe pour l’heure que dans les équations des physiciens. Ci-dessous, la courbe rouge décrit la variation réelle de la durée du jour depuis le début du mois de mars (graduée en millième de secondes, avec une précision de mesure de l’ordre de 4 microsecondes). La théorie et la mesure. « Le 11 mars [date du séisme au Japon], la variation de la durée du jour est de l’ordre de 40 microsecondes. En quête de sciences, avec Florian Gouthière Photo : NASA
Plate tectonics: When we discovered how the Earth really works Image copyright The Geological Society, McKenzie Archive What would you put on your list of the great scientific breakthroughs of the 20th Century? General relativity? Quantum mechanics? Something to do with genetics, perhaps? One discovery that ought to be on everyone's rundown is plate tectonics - the description of how the rigid outer shell of our planet (its lithosphere) moves and is recycled. The theory celebrates its 50th anniversary this year and some of the key players who put the framework together are currently in London to mark the occasion with a special conference at The Geological Society. The truly great ideas in science not only seem brilliantly simple and intuitive when they come into focus, they also then have this extraordinary power to answer so many other questions in Nature. Plate tectonics is a perfect example of this. "We had no idea what were the cause of earthquakes and volcanoes and things like that," recalls Dan McKenzie. Although seen as an "aha!"
Réseau National de Surveillance Sismique / ReNaSS Le Réseau National de Surveillance Sismique (RéNaSS) est un volet du Service National d’Observation en Sismologie, labellisé par l’INSU. Il est né de la nécessité d’améliorer la couverture instrumentale de la France au début des années 1980 avec l’installation d’environ 75 stations courte-période réparties sur l’ensemble du territoire métropolitain. Depuis les années 2010, en plus de la modernisation du réseau courte-période (conversion progressive vers un réseau large-bande), l’infrastructure de recherche RESIF-RLBP a permis de densifier le réseau de surveillance. Le RéNaSS, à travers son site central localisé à l’Ecole et Observatoire en Sciences de la Terre (EOST) à Strasbourg, est en charge : Ces localisations sont validées et mises à jour pendant les jours ouvrés (du lundi au vendredi) par un analyste sismologue. Le RéNaSS et le BCSF ont fusionné depuis 2016.
