Poor nutrient-holding capacity, good water infiltration capacity, and good aeration properties are examples of what type of particle found in soil? Clay Silt Sand Loam Humus

The process of weathering produces what type of rock? Igneous Metamorphic Sedimentary Volcanic None of the above

The horizon of soil also known as the topsoil layer, that contains humus, minerals, and roots, and tat is rick in living organisms is known as the: A layer B layer C layer D layer O layer

The San Andreas Fault in California occurs at: A convergent boundary A divergent boundary A transform boundary A subduction zone An oceanic ridge

Earth’s surface is part of the: Asthenosphere Lithosphere Benthosphere Troposphere Stratosphere

The benefits of bioengineered crops include all of the following except: Resistance to plant diseases Increased genetic variety Reduced need for pesticides Reduced need for water Resistance to salinization

Why do nonnative invasive species often become pests? They don’t have many offspring. They increase biodiversity. They can outcompete native species. They stay in one area and take it over. They can have many predators that eat them as prey.

The best way to protect biodiversity is to: Pass endangered species laws. Protect world’s ecosystems. Build more zoos. Import species from other countries. Use captive breeding and re-release programs.

Cutting all small trees but leaving a few mature seed-producing trees is referred to as: Selective cutting Clear-cutting Shelterwood cutting Seed-tree cutting Deforestation

Establishing a wildlife refuge would be described best as: Conservation Preservation Restoration Consumptive use Productive use

A power company uses natural gas to run a plant and then uses the waste heat to produce electricity. This is an example of: Oil dependence Primary recovery Cogeneration Reclamation Turbogenerators

The stages of coal, classified by heat and sulfur content, from the softest and most moist to the hardest and driest are: Bituminous, anthracite, peat, lignite Lignite, anthracite, peat, bituminous Bituminous, peat, lignite, anthracite Peat, lignite, bituminous, anthracite Peat, bituminous, anthracite, lignite

Strip mining is detrimental to the environment for all of the following reasons except: Contamination of groundwater Disruption of habitat Air pollution Aesthetic appeal Destruction of wetlands

Law Flashcards

Clean air act (1970): federal law that regulates air emissions from area, stationary, and mobile sources Clean water act (1970’s): established the basic structure for regulating discharges of pollutants into the waters of the United States. It gave EPA the authority to implement pollution control programs such as setting wastewater standards for industry.

3. Comprehensive Environmental Response, Compensation, and Liability Act (Superfund ) (CERCLA): CERCLA (pronounced SIR-cla) provides a Federal “Superfund” to clean up uncontrolled or abandoned hazardous-waste sites as well as accidents, spills, and other emergency releases of pollutants and contaminants into the environment *Governed by the EPA

That’s all for now. More laws to come later…
