- 10501: Nuclear Waste Management
- ... approaches to solidification. These include calcination, vitrification, and incorporation of waste into ceramics and synthetic materials. Calcination is a process in which the liquid waste is sprayed through an atomizer and then dried at a high temperature. This results in calcine (which is highly radioactive) and temporarily stored in bins for further processing. Vitrification consists of the mixing of calcined waste with borosilicate glass grit. This is melted in a specialized ...
- 10502: Landfills: A Growing Menace
- ... become a profitable enterprise, both for the economically disadvantaged and for the average homeowner trying to offset the ever-increasing cost of garbage collection. Construction waste is now barred from landfills in most areas; this high volume material is now recycled or put to Earth-friendly uses, such as making barrier reefs. Plans for the safe incineration of refuse to generate electric power have presented some highly contentious issues. The ash ...
- 10503: Hurricanes
- ... a week or more (example: Hurricane Dorthy) In that time, it may travel tens of thousands of miles over the sea and land. At sea, hurricane winds whip up giant waves up to 20 feet high. Such waves can tear freighters and other oceangoing ships in half. Over land, hurricane winds can uproot trees, blow down telephone lines and power lines, and tear chimneys off rooftops. The air is filled with ...
- 10504: Estuaries
- ... the curve of an expansive barrier beach. Wherever there are estuaries, there is a unique beauty. As rivers meet the sea, both ocean and land contribute to an ecosystem of specialized plants and animals. At high tide, seawater changes estuaries, submerging the plants and flooding creeks, marshes, panes, mudflats or mangroves, until what once was land is now water. Throughout the tides, the days and the years, an estuary is cradled ...
- 10505: Effects of Deforestation
- ... s food supply, threatens many human resources and has profound implications for biological diversity. Another negative environmental impact of deforestation is that it causes climate changes all over the world. As we learned in elementary school, plant life is essential to life on earth as it produces much of the oxygen that is required for humans and other organisms to breathe. The massive destruction of trees negatively effects the quantity and ...
- 10506: Deciduous Forests
- ... of water and the amount of organic nutrients in the soil are important a-biotic factors that can affect the ability of any species to thrive in an area. The northern side also contains a high concentration of large rock, virtually not present in the Tulip side. This indicates that there is a difference in the soil construction, given that soil is produced by the break down of local parent material ...
- 10507: Chinook Salmon
- ... the holes in the nets are large enough for the head of the fish to fit through, and then the mesh gets caught in the fish's gills. Others are designed to circle around a school of fish and then is drawn shut. New technologies have developed factory stern trawlers which easily haul netloads of up to 100 metric tons of fish. However, when catching the salmon, fisherman use pound nets ...
- 10508: Air Polution
- ... and hydrogen. Hydrocarbons also arise from gasoline-powered vehicles and from industrial processes. Hydrocarbons are an important part of the production of photochemical smog (Hodges 61). The last type is nitrogen oxides that come from high- temperature combustion, such as that occurring in motor vehicle engines, electric power plants and other fuel usage. Nitrogen oxide contributes to acidity in precipitation and production of photochemical smog. Nitrogen oxide is also dangerous it ...
- 10509: Problems Caused By Air Pollution
- ... 8). Thousands of lakes and streams, across the northeastern part of the United States and the mid-Atlantic states, in Canadian provinces, in Scandinavian countries and in other parts of Europe, have acid concentrations so high that aquatic food chains are destroyed, and fish die off (Gay 26). Land is also destroyed by acid rain. In North American and European forests, and tropical rainforests in Mexico and Central America, vast numbers ...
- 10510: Acid Rain Legislation
- ... effects they can have on the environment. Acid rain is harmful to the environment because of it's low pH. It can harm the biotic components of earth, and also the abiotic components. It's high acidity degrades soil to the point where it cannot support any type of plant life. Trees in forests are killed over long-term exposure. When these trees are killed, an imbalance in the hydrologic cycle ...
