What is gully erosion? Gully erosion is the removal of soil along drainage lines by surface water runoff. Once started‚ gullies will continue to move by headward erosion or by slumping of the side walls unless steps are taken to stabilise the disturbance. Repair work done in the early stages of newly formed gullies is easier and more economical than letting the problem go unchecked for too long. Large gullies are difficult and costly to repair. What causes gully erosion ? Gully erosion occurs

bub Weather is the state of the atmosphere at a given time and place‚ with respect to variables such as temperature‚ moisture‚ wind velocity‚ and barometric pressure. Weather can be classified as day to day temperature and precipitation activity‚ where climiate is average atmospheric conditions over longer periods of time. Weather occurs from temperature and moisture differences between one place and another. These differences can occur due to the sun angle at any particular spot. The strong

Jessica Guerrero Geology 110 November 30‚ 2009 Chapter 6. Weathering Describe the role of external processes in the rock cycle. External processes include weathering which is the disintegration and decomposition of rock at or near earth’s surface. Mass wasting which is the transfer of rock material downslope under the influence of gravity. And erosion‚ which is the removal of material by a mobile agent‚ usually water‚ wind or ice.. These are all called external processes because

Assignment: Earthquakes Diamonds University of Phoenix September 25‚ 2011 Diamonds As the famed saying goes‚ “Diamonds are a girl’s best friend”. Not only are diamonds a girls friend but also industries friend as well. Diamonds are formed approximately 100 miles below the surface. Diamonds are a crystalline form of carbon. Carbon is crystallized in super heat and pressure in the boiling magma. Even apart from its rarity and value‚ diamond is a remarkable mineral (Murck‚ B. W.‚ Skinner

pros and cons of weathering steel:: "Weathering" means that due to their chemical compositions‚ these steels exhibit increased resistance to atmospheric corrosion compared to unalloyed steels. This is because the steel forms a protective layer on its surface under the influence of the weather. The corrosion-retarding effect of the protective layer is produced by the particular distribution and concentration of alloying elements in it. The layer protecting the surface develops and regenerates

Chemical Weathering is the process of disintegration or decomposition of rocks due to chemical processes. It alters the intrinsic properties such as chemical structure‚ composition and density of the minerals that the rock is made up of. A rock’s susceptibility to Chemical Weathering depends on the stability of the minerals in it. Rock is composed of minerals that are generally quite stable at the time of formation. When there is variation in the surrounding environment‚ some minerals tend to

The definition of weathering is to wear away or change in appearance or texture due to long exposure to air. This concept is also applicable to the human body. This is called the weathering hypothesis. The weathering hypothesis was coined by Dr. Geronimus‚ which states that African Americans in the United States experience early health deterioration‚ measured by biological indicators of repeated exposure to and adaptation to stressors (Geronimus‚ Hicken‚ Pearson‚ Seashols‚ Brown‚ & Cruz‚ 2010).

everyone inevitably experiences insecurity towards their body image. In one of her most famous poems‚ ’Weathering’‚ Fleur Adcock addresses her own personal experience with the standards of beauty. She begins the poem with a strong critical tone‚ natural imagery and interesting figurative descriptions in order to associate and connect her most recurring themes of nature and place. Adcock opens ’Weathering’ with the candid lines: "Literally thin-skinned‚ I suppose‚ my face/catches the wind off the snow
