Latest Erosion Stories
Typically we think of rainfall as cleaning the air by removing dust as it falls through the atmosphere and helping plants grow that protect and hold the soil. But a new NASA-funded study looking at some of the world's dustiest areas shows that heavy downpours can eventually lead to more dust being released into the atmosphere.
By Ed Stoddard CHIKWAWA, Malawi (Reuters) - Jennifer Chikapa is carting Malawi's future away on her head.
Wind generator vanes can suffer degradation by erosion, particularly at their outer edge, produced by particles (dust, sand, etc.) which are present suspended in the air. Because of this, the ever increasing presence of wind parks in zones of extreme climate make it puts an onus on optimising the protection coating material, with the aim of guaranteeing good yields, even in the most extreme conditions.
The thousands of oval lakes that dot Alaska's North Slope are some of the fastest-growing lakes on the planet.
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,...
