Geologist Find Unusual Land Formation On Mars
2012-03-23 06:10:46

Geologists at the University of Washington found that a previously unseen landform on Mars could help provide a window into the geological history of the Red Planet. The "periodic bedrock ridges", or PBRs, look like sand dunes, but the scientists say that they are actually made from wind erosion of bedrock. "These bedforms look for all the world like sand dunes but they are carved into hard rock by wind," David Montgomery, a UW professor of Earth and space sciences, said in a press...

Taking inspiration from the yellow fattail scorpion, which uses a bionic shield to protect itself against scratches from desert sandstorms, scientists have developed a new way to protect the moving parts of machinery from wear and tear. A report on the research appears in ACS' journal Langmuir. Zhiwu Han, Junqiu Zhang, Wen Li and colleagues explain that "solid particle erosion" is one of the important reasons for material damage or equipment failure. It causes millions of dollars of damage...

TAU researchers use organic polymer to protect scorched soil from erosion Wildfires cause tragic losses to life, property, and the environment. But even after the fire rages, the damage is far from done. Without vegetation, bare, burnt soil lies vulnerable to erosion, which can impede efforts towards natural forest regeneration. Now Assaf Inbar, a graduate student at Tel Aviv University's Porter School of Environmental Studies, together with his supervisors Prof. Marcelo Sternberg of...

Something's up with the weather in Namibia, say geoscientists Kyle Nichols of Skidmore College in Saratoga Springs, N.Y., and Paul Bierman of the University of Vermont in Burlington, Vt. Nichols and Bierman should know. They're just back from the western mountains and coastal plain of this sparsely populated African country. Usually, western Namibia is a dusty place where the stream beds are sand and the "lakes" are nothing more than flats of dried mud. Not now. This year, rivers...

By Joshua E. Brown, University of Vermont Every mountain and hill shall be made low, declared the ancient prophet Isaiah. In other words: erosion happens. But for the modern geologist a vexing question remains: how fast does this erosion happen? For more than a century, scientists have looked for ways to measure and compare erosion rates across differing landscapes around the globe"”but with limited success. "Knowing the background rate of erosion for a place is extremely important,"...

There is literally a way to undercut dust emissions in the very driest parts of the Pacific Northwest's Columbia Plateau region, according to a U.S. Department of Agriculture (USDA) scientist. Brenton Sharratt, research leader at the USDA Agricultural Research Service (ARS) Land Management and Water Conservation Research Unit in Pullman, Wash., found that undercutting is a promising conservation tillage technique on fallow fields. ARS is USDA's principal intramural scientific research...

Researchers from the Polytechnic University of Catalonia (UPC) have developed a method for evaluating the vulnerability of coastal regions to the impact of storms. The method, which has been applied on the Catalan coastline, shows that one-third of the region's coasts have a high rate of vulnerability to flooding, while 20% are at risk of erosion. "Until now there was no tool for evaluating coastal storm vulnerability that could quantify the processes and the probabilities of these events...

Scientists develop model to assess the impact agroforestry windbreaks have on farming operations Agroforestry, the deliberate placement of trees into crop and livestock operations, can help capture substantial amounts of carbon on agricultural lands while providing production and conservation benefits. However, we currently lack tools for accurately estimating current and projected carbon values in these systems. In North America, windbreaks are an effective carbon-capturing option. Only...

To understand the long-term effects of a prolonged tropical storm in the Panama Canal watershed, Robert Stallard, staff scientist at the Smithsonian Tropical Research Institute and research hydrologist at the U.S. Geological Survey (USGS), and Armando Ubeda, the LightHawk Mesoamerica program manager, organized four flights over the watershed to create a digital map of landslide scars. Two feet of heavy rain inundated the Panama Canal watershed between Dec. 7 and 10, 2010. Landslides tore down...

In one of his songs Bob Dylan asks "How many years can a mountain exist before it is washed to the sea?", and thus poses an intriguing geological question for which an accurate answer is not easily provided. Mountain ranges are in a constant interplay between climatically controlled weathering processes on the one hand and the tectonic forces that cause folding and thrusting and thus thickening of the Earth's crust on the other hand. While erosion eventually erases any geological obstacles,...

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,...
