Q1. You are asked to create soil that would be considered very fertile. What would you include in your "recipe?" I would try to create a soil order all of my own‚ combining Inceptisols and Mollisols unique characteristics. My terrain for my soil to be placed would be on a mostly flat to gently sloping surface to provide good drainage‚ minimum erosion‚ and sufficient time for nutrients to drain into the soil. My “O” soil horizon will be mostly compost made from fallen leaves and other organic

Pollution is the introduction of contaminants into the natural environment that cause adverse change. Pollution can take the form of chemical substances or energy‚ such as noise‚ heat or light. Pollutants‚ the components of pollution‚ can be either foreign substances/energies or naturally occurring contaminants. Pollution is often classed as point source or nonpoint source pollution. There are 6 (six) types of pollution that are going to be discussed in this site‚ namely air‚ water‚ noise‚ land

Pollution is the introduction of harmful substances or products into the environment. It is a major problem in America and as well as the world. Pollution not only damages the environment‚ but damages us also. It has cause many problems ranging from lung cancer to the greenhouse effect. It is among us all‚ but we continue to live our lives in our own filth. What is the reason behind this flawed logic? In this paper I will examine the problems and solutions for this issue. Automobiles are undeniable

Pollution Introduction Pollution is when water‚ air or land becomes very dirty. Pollution can come in 4 different types effecting different types of areas in the world. Air pollution affects the air‚ water pollution affects the water and marine life‚ land pollution effects the land destroying life and the environment and there is also noise pollution that can effect our hearing. We all contribute to pollution in some way or another. Whether it be with a large amount or small amount we can still

CHAPTER 8 Soil Compaction Soil compaction is one of the most critical components in the construction of roads‚ airfields‚ embankments‚ and foundations. The durability and stability of a structure are related to the achievement of proper soil compaction. Structural failure of roads and airfields and the damage caused by foundation settlement can often be traced back to the failure to achieve proper soil compaction. Compaction is the process of mechanically densifying a soil. Densification

Environmental pollution is the biggest menace to the human race on this planet today. The environment consists of earth‚ water‚ air‚ plants and animals. If we pollute the environment‚ the existence of man and nature will be hampered. Although most of people know that but they still destroy their own life. There a numerous kinds of environment pollution. However‚ I split it to 3 groups: water pollution‚ air pollution and soil pollution. Nowadays‚ the water of rivers and sea all over the worlds is
