Geophysicist And Mathematicians Team Up To Describe How River Rocks Round
2014-02-13 13:58:08

University of Pennsylvania For centuries, geologists have recognized that the rocks that line riverbeds tend to be smaller and rounder further downstream. But these experts have not agreed on the reason these patterns exist. Abrasion causes rocks to grind down and become rounder as they are transported down the river. Does this grinding reduce the size of rocks significantly, or is it that smaller rocks are simply more easily transported downstream? A new study by the University of...

Bacterial 'Syringe' Necessary For Development Of Marine Animals
2014-01-15 08:43:59

California Institute of Technology If you've ever slipped on a slimy wet rock at the beach, you have bacteria to thank. Those bacteria, nestled in a supportive extracellular matrix, form bacterial biofilms—often slimy substances that cling to wet surfaces. For some marine organisms—like corals, sea urchins, and tubeworms—these biofilms serve a vital purpose, flagging suitable homes for such organisms and actually aiding the transformation of larvae to adults. A new study at the...

Soil erosion may reveal ancient water management in Mahendraparvata Soil erosion and vegetation change indicate approximately 400 years of intensive land use around the city of Mahendraparvata in the Phnom Kulen region beginning in the mid 9th century, with marked change in water management practices from the 12th century, according to results published January 8, 2014, in the open access journal PLOS ONE by Dan Penny from the University of Sydney and colleagues from other institutions....

Utah Copper Mine Landslide Triggered Earthquakes
2014-01-06 07:39:40

University of Utah Record-breaking slide would bury Central Park 66 feet deep Last year's gigantic landslide at a Utah copper mine probably was the biggest nonvolcanic slide in North America's modern history, and included two rock avalanches that happened 90 minutes apart and surprisingly triggered 16 small earthquakes, University of Utah scientists discovered. The landslide – which moved at an average of almost 70 mph and reached estimated speeds of at least 100 mph – left a...

Sandstone Bacteria thrives on oil iron

April Flowers for redOrbit.com - Your Universe Online Able to withstand high heat, high salinity, low oxygen, utter darkness and pressures that would kill most other organisms, the bacteria Halomonas is a very hardy breed. Traits such as these enable these microbes to eke out a living in deep sandstone and have proven to be useful for hydrocarbon extraction and carbon sequestration. The new study, published in Environmental Microbiology, gives the first unobstructed view of the...

Desertification
2013-04-02 09:46:56

Desertification is a form of land degradation in which a comparatively dry land area becomes more and more arid, normally losing its bodies of water along with its wildlife and vegetation. This is a result of a variety of factors, such as climate change and human activities. Desertification is an important global, ecological, and environmental issue. There is substantial controversy over the proper definition of the term “desertification”. The most broadly accepted of these is that of...

Land Degradation
2013-04-02 09:20:15

Land degradation is a process in which the value of the biophysical environment is affected by one or more combination of human-induced processes acting on the land. It is also the gradual destruction or reduction of the quality and quantity of human activities, animal activities or natural means. It is viewed as any change or disturbance to the land perceived to be deleterious or unwanted. Natural hazards are not included in the causes; however, human activities can indirectly affect...

Erosion
2013-04-01 12:48:39

Erosion is the process by which rock and soil are taken from the surface of the Earth by exogenetic processes like wind or the flow of water, and then transported and deposited in another location. While erosion is a natural process, human activities have increased by 10 to 40 times the rate at which erosion is happening globally. Excessive erosion results in problems such as desertification, decreases in agricultural productivity because of land degradation, sedimentation of waterways,...

Soil Salinity
2013-04-01 11:15:13

Soil salinity is the salt content within the soil; the process of increasing the content of salt is known as salination. Salt is a natural element of water and soils. Salination can be a result of natural processes such as the gradual withdrawal of an ocean or mineral weathering. It can be caused by artificial processes such as irrigation as well. Soils that are affected by salt are a result of excess accumulation of salts, normally most obvious at the surface of the soil. Salts can be...

Dryland Farming
2013-03-15 11:32:48

Dryland farming is farming without the aid of irrigation and only with the amount of rain fall given by Mother Nature. Dryland farming is typical in arid regions such as Southwestern United States, Mexico, the Middle East, and other regions that are known for growing grains. Dryland farming is practiced in all parts of Australia with the exception of the Northern Territory. Process Dryland farming involves the constant assessing of the amount of moisture present or lacking for any given...
