longer than a decade! The Dust Bowl‚ also known as the Dirty Thirties‚ was a period of severe dust storms that greatly hurt agriculture in the US and Canada during the 1930s. Severe droughts and a failure to dryland farming methods to prevent wind erosion caused the phenomenon. The Dust Bowl was in the southern states‚ mainly near the coast. The Dust Bowl drought started in 1934 and ended in 1937. The Dust Bowl was a long period of time where people had nothing but their own

1. Make a simple drawing of Earth’s three major zones. Describe the composition of the zones. Briefly explain the internal process of plate tectonics and the external geological process of erosion. ● Continental Plates (Crust)- consists of the continental crust‚ and the oceanic crust ● Mantle- solid rock‚ but under its rigid outermost part is a zone of very hot‚ partly melted rock that flows like soft plastic. The plastic is asthenosphere. ● Core- is very hot and has a solid inner part‚ surrounded

boiler Since the late 1800s‚ the use of strip mining to extract coal from the earth has left scars on land and led to land erosion. Unabated erosion leads to toxic chemical seepage in streams and other water bodies‚ which destroys wildlife habitats. While some coal mining companies currently work to rehabilitate land destroyed by mining‚ mining continues to lead to more erosion and pollution. Mercury and Other Pollutants Like other fossil fuels‚ coal-burning boilers emit dangerous pollutants including

Tourism in the Lake District Attracts hundreds of visitors daily meaning the main attractions can gain a vast income to improve. Cat Bells is an easy climb so a lot of tourists choose to climb this small mountain. This is causing footpath erosion because of the constant use of the same path. The constant use of certain areas cause landscape scarring 20% of Lake District homes are second homes or holiday homes to let Locals earn a lot from renting out their homes in summer to tourists Holiday cottages

Every individual has responsibility to use natural resources judiciously. This will give equal opportunity to all to use the resources for the benefit of mankind. One should not be selfish to spend the available resources without thinking of other fellow beings. There is no limit to spend natural resources if available plenty but at the same time one should realize that natural resources are non-renewable sources. The future also depends on such resources. Every individual should think himself or

weaknesses such as over harvesting‚ land erosion‚ and illegal logging. “Colombia has lost 2‚224‚000 acres of natural forest and some of that was due to soil erosion. The main reason they have lost so much forest though is because of deforestation (the removal of trees).” (http://soilcentralsouthamerica.blogspot.com.au/2010/10/soil-erosion-in-colombia.html) As Soil Issues in Central and South America says‚ one of the major problems in Colombia is soil erosion due to deforestation because of the increasing
