What are minerals, what are their important physical properties, how are they formed (in general) where are they found in nature (in general with any examples that you have researched). Why are they important and how are they used in society with concrete, specific examples of at least 3 minerals and the many ways each mineral is used.

Soil Components and Properties
Soil is a heterogeneous entity which is described by its physico-chemical properties. Make a list of these physico-chemical properties and describe how each one determines the suitability (or otherwise) of the soil for plant growth.

The book talks about different kinds of communities
and the different interactions that take place in these
communities. Chapter 6 discusses eleven different types of biomes
and the impact humans have had on these environments. Read all
eleven descriptions. Select the three biomes that you believe have
been the most negatively impacted by humans. Select one
negative impact humans have had on each biome. Suggest at least one
way that we can work to help cut down or eliminate the human
threats that the biomes face.
You will have three biomes; you will write about one negative
impact and one solution with each biome.

Hazardous Waste Categories 2 page essay
This assignment is designed to familiarize you with the physical, chemical, and hazardous properties that are used to properly classify hazardous wastes. The management and disposal of hazardous wastes depends on which category the hazardous waste is assigned. Some wastes are neutralized; others are incinerated or solidified. Properly classifying a hazardous waste ensures that the waste is compatible with allowable treatment technologies available for each class of hazardous waste, and it helps to ensure that workers will not be harmed when treating a misclassified waste.
Your assignment is to answer the following questions on hazardous waste in two parts.
Part A
Describe the different categories of hazardous waste that can be found in homes and residential buildings. Explain this using a table listing the properties that make each category hazardous. Based on the hazardous properties, propose your idea on how these wastes should be stored while waiting for periodic collection by the local community.
Part B
For a comparison between residential and industrial generators, what are four examples of hazardous wastes that are generated in a vehicle maintenance facility? Explain using a table to list the properties that make each category hazardous. For each hazardous waste identified, in your opinion, what are the biggest concerns that need to be addressed when the wastes are in storage for collection by a waste hauler?

Explain why the same surface roughness values do not necessarily represent the same type of surface. Please give some examples. Hint: surfaces that have the same Ra values, may be are very different geometrically and have different tribological performance. Give examples.

Cubic boron nitride is used as an abrasive in machining steel as an alternative to diamond, whereas hexagonal boron nitride is frequently used as a lubricant in electronic and high-temperature applications. Explain how these different properties result from different crystal structures and bonding in this material. (Hint: think about the different crystal structures of carbon!)

How do detrital sedimentary rocks differ from chemical sedimentary rocks? Explain how the soil pedon contains all aspects of mechanical and chemical weathering leading to sedimentary rock formation (include all of the different layers and the different types of rocks they would represent if exposed to the surface).
