Environmental Benefits of Nanotechnology
Nanotechnology contribute significantly to environmental and climate protection by saving raw materials, energy and water as well as by reducing greenhouse gases and hazardous wastes.
Answer A: Sedimentary Rocks are a product of the surface processes of the earth (weathering, erosion, rain, streamflow, wind, wave action, ocean circulation).
Answer B: Organic weathering happens when plants break up rocks with their growing roots or plant acids help dissolve rock. Once the rock has been weakened and broken up by weathering it is ready for erosion.
Answer D: Sediment moves from one place to another through the process of erosion.
Answer C:Suspension occurs when very fine dirt and dust particles are lifted into the wind
Answer B. Lignite, often referred to as brown coal, is a soft, brown, combustible, sedimentary rock formed from naturally compressed peat. It is considered the lowest rank of coal due to its relatively low heat content.
Answer D. Anthracite, often referred to as hard coal, is a hard, compact variety of coal that has a submetallic luster
Answer C. Bituminous coal or black coal is a relatively soft coal containing a tarlike substance called bitumen or asphalt. It is of higher quality than lignite coal but of poorer quality than anthracite.
G = Generator, F= Turbine, E = steam, H= condenser, D= Heat exchanger, C= Containment structure or shell, B= Control rods, A = Uranium fuel input (reactor core), J= Pressure vessel, I = Coolant passage .
Global Peak production is the theorized point in time when the maximum rate of extraction of petroleum is reached, after which it is expected to enter terminal decline.
Dose-response graph: 25% population would be killed.
LD50 = 7 Hypothetical units
LD stands for "Lethal Dose". LD50 is the Median Lethal Dose amount of a material, given all at once, which causes the death of 50% (one half) of a group of test animals.
A dose response curve refers to the relationship between an effect of a drug and the amount of drug given. Scientist use the Dose response curves as they are essential to understand the drug's safe and hazardous levels, so that the therapeutic index can be determined and dosing guidelines can be created.
It is difficult to determine the level of exposure to a particular toxic chemical that will cause harm to humans. Sometimes a human population that has been exposed to a toxic substance (usually at work or from an environmental source) is compared with a population that has not been exposed. If the exposed population shows an increase in a certain health effect, that health effect may be related to the chemical exposure.
B- wastes being decomposed and low-oxygen fishes present.
D: stream recovered, with a return of clean water organisms.
A: stream begun to return a normal status following the oxygen sag
C: organisms that require oxygen most likely to be absent
Point source pollution means pollution that comes from a single, identifiable source or point whereas Nonpoint source pollution means pollution whose source cannot be traced back to a single thing. Nonpoint source pollution is pollution that is more diffuse.
Point source pollution include sewage pipes releasing sewage into a ditch, smokestack style factory chimneys and oil spills. NPS pollution is caused by rainfall or snowmelt moving over and through the ground.
Phytodegredation: C
Rhizofiltration:A
Photostabilization:D
Phytoextraction: B
Hazardous waste threatens human health or the environment if it is carelessly thrown away, dumped into the ground or handled improperly. Solid waste is commonly known as trash or garbage. It refers to the overall garbage created by a community, including household waste, as well as the waste generated by businesses, schools and institutions.

Ideas may be beneficial for the environment and the urban dwellers.
Electricity, water, and human labor are more expensive in a city. Transportation costs are more expensive, to transport the raw materials to the city and the ship products to their final destinations.
For the city of London, England, 58 times more it's area required to provide the input resources.
4 earths are required.
