Top 10 Questions for Environmental Geology Laboratory Instructor Interview

1. How would you design an experiment to determine the porosity and permeability of a rock sample?

• Determine the mass and volume of the rock sample.
• Measure the volume of water absorbed by the rock sample using a graduated cylinder.
• Calculate the porosity of the rock sample using the following formula: porosity = (volume of water absorbed / volume of rock sample) x 100%.
• Measure the flow rate of water through the rock sample using a permeameter.
• Calculate the permeability of the rock sample using the following formula: permeability = (flow rate x viscosity of water x length of rock sample) / (cross-sectional area of rock sample x pressure drop).

2. What are the different types of weathering processes, and how do they affect the properties of rocks?

Physical weathering

• Frost weathering: Occurs when water seeps into cracks in rocks and freezes, causing the cracks to expand and break the rock apart.
• Thermal weathering: Occurs when rocks are heated by the sun and then cooled by the night air, causing the rocks to expand and contract and eventually break apart.
• Exfoliation: Occurs when thin layers of rock peel off from the surface of a rock due to changes in temperature or pressure.

Chemical weathering

• Hydrolysis: Occurs when water reacts with minerals in rocks, causing the minerals to break down and form new minerals.
• Oxidation: Occurs when oxygen reacts with minerals in rocks, causing the minerals to break down and form new minerals.
• Carbonation: Occurs when carbon dioxide reacts with minerals in rocks, causing the minerals to break down and form new minerals.

Biological weathering

• Plant roots: As plant roots grow, they can break apart rocks.
• Animals: Animals can burrow into rocks and break them apart.
• Microorganisms: Microorganisms can produce acids that can dissolve minerals in rocks.

3. What are the different types of rocks, and how are they classified?

• Igneous rocks: Formed from the cooling and solidification of molten rock.
• Sedimentary rocks: Formed from the accumulation and cementation of sediments.
• Metamorphic rocks: Formed from the alteration of existing rocks by heat, pressure, or chemical reactions.

4. What are the different types of faults, and how do they form?

• Normal faults: Form when the hanging wall moves down relative to the footwall.
• Reverse faults: Form when the hanging wall moves up relative to the footwall.
• Strike-slip faults: Form when the rocks on either side of the fault move horizontally past each other.

5. What are the different types of folds, and how do they form?

• Anticlines: Folds that have a convex-up shape.
• Synclines: Folds that have a concave-up shape.
• Monocline: Folds that have a single limb.

6. What are the different types of unconformities, and how do they form?

• Angular unconformity: Occurs when two sets of rocks have different orientations and are separated by an erosional surface.
• Disconformity: Occurs when two sets of rocks have the same orientation but are separated by an erosional surface.
• Nonconformity: Occurs when two sets of rocks have different compositions and are separated by an erosional surface.

7. What are the different types of groundwater, and how do they differ in terms of their quality and availability?

• Unconfined groundwater: Groundwater that is not confined by an impermeable layer of rock or clay.
• Confined groundwater: Groundwater that is confined by an impermeable layer of rock or clay.
• Perched groundwater: Groundwater that is separated from the main groundwater table by an impermeable layer of rock or clay.

8. What are the different types of water pollution, and what are their effects on human health and the environment?

• Point source pollution: Pollution that comes from a single source, such as a factory or sewage treatment plant.
• Nonpoint source pollution: Pollution that comes from multiple sources, such as agricultural runoff or stormwater runoff.
• Chemical pollution: Pollution caused by the presence of harmful chemicals in water.
• Biological pollution: Pollution caused by the presence of harmful microorganisms in water.

9. What are the different types of water treatment methods, and how do they work?

• Filtration: Removes suspended solids from water by passing it through a filter.
• Coagulation and flocculation: Removes suspended solids from water by adding chemicals that cause them to clump together and settle out.
• Disinfection: Kills harmful microorganisms in water by adding chemicals such as chlorine or ozone.

10. What are the different types of environmental regulations related to water, and how do they affect businesses?

• The Clean Water Act: Regulates the discharge of pollutants into waters of the United States.
• The Safe Drinking Water Act: Regulates the quality of public drinking water supplies.
• The Resource Conservation and Recovery Act: Regulates the generation, transportation, storage, and disposal of hazardous waste.
