poisonous to fish and other ocean life. Nutrients may cause nuisance growth of aquatic weeds and algae. Weeds can make a lake unsuitable for swimming and clog waterways. Suspended matter such as soil and wash off from plowed field causes silt when it rains. When silt enters the waterway the waters depth is reduced and ocean life and their environment may suffocate. To combat this problem I would create a detailed water pollution guide. The guide would have material on source water assessments and

There were four main ancient River Valley civilizations: the Fertile Crescent of Mesopotamia‚ the Nile River of Egypt‚ the Indus River of India‚ and the Yellow River of China. These civilizations showed specific similarities and contrasting differences. Many of these differences and similarities showed up in the three categories of the technological advances‚ the types of government‚ and the geography of the civilization. Two civilizations that are very interesting to delve deeper into and study

Hydrometer analysis is used to determine the grain-size distribution of a soil which is similar to the sieve analysis done in an earlier lab. Hydrometer analysis can be combined with the sieve analysis to determine the amounts (percents) of fines (silts and clays) in a sample. The hydrometer analysis doesn’t require the soil to be passed through a series of sieves like in the sieve analysis. The analysis measures the rate of sedimentation. The larger the particle‚ the quicker it will fall out of

It is hard to find anyone in Bangladesh who does not have any memory of a river. Someone may have a lot of memories of swimming in a river while someone else may have memories of journey by boat or launch on rivers. On the other hand‚ many of us also experience the cruel face of rivers during flood. But‚ memory of river is a common characteristic of the people of Bangladesh‚ a country crisscrossed by rivers. Actually‚ the rivers of Bangladesh mark both the psychology of the nation and the life

Writer: Linber LewisSchool: President’s College‚ GuyanaIf one asks the question‚ what can floods do?‚ then the following may seem like fitting answers. During the summer monsoon season‚ heavy rains cause destructive floods in Southeast Asia. In China‚ the floods of the Huang He River have been so frequent and devastating that the river is called Chinas Sorrow. Likewise in the US‚ record spring and summer rains in 1993 caused the Mississippi Rover to overflow its banks‚ flooding farms and towns from

Aeolian features form in areas where wind is the primary source of erosion. The particles deposited are of sand‚ silt and clay size. The particles are entrained in by one of four processes. Creep occurs when a particle rolls or slides across the surface. Lift occurs when a particle rises off the surface due to the

Assimilation Versus Preservation By the middle of the 19th century‚ the Indian way of life had begun to be disturbed through advancements into the West in many ways‚ the most important of which was the construction of the transcontinental railroad. Railroads pierced through the heart of the continent while slashing through Indian lands dividing the once open ranges of the Great Plains and splicing the economies of the East and West. The Indians had faced many battles and suffered great losses‚
