Clemson Geology 1010- Exam 4 Latest Update Graded A Groundwater: why should we care? YOU MUST have this resource to survive hydrologic cycle ocean = biggest reservoir (1,000,000 units) 2nd largest = glacier (26000 units) 3rd largest = ground water (15000 units) runoff water that runs across the landscape and eventually ends up in a river or stream and continues to move downstream infiltration water soaks INTO ground, becomes part of ground water supply porosity The percentage of the total vo...

Geology Exam #4 Questions With Answers What is a parent isotope? A daughter? Parent Isotope: An isotope that undergoes decay to form a daughter isotope Daughter Isotope: May be stable or may decay to form another daughter (formed from the parent isotope) What is a half‐life? The time required for 1/2 of a radioactive isotope to decay ion a stable daughter isotope What is meant by mass wasting? The general term for all gravity induced movement of material down a slope. How a...

Hydrolic Cycle correct answers movement of water through the hydrosphere Hoe does water get trapped in certain parts of the hydrolic cycle? correct answers - longest in ice caps (10,000-200,000 years) - shortest in living organisms (hours-days) - shallow-deep ground water (100-10,000 years) so once it gets polluted it's really hard to clean Why are we so interested in groundwater? correct answers - water stored in sediments or rocks underground provides ~2/3 of the water we use - its t...

A barrel of oil is priced at $6, to switch to natural gas, what would natural gas need to be priced at? correct answers The price of natural gas must be more than $36. Is nuclear power a non-renewable, renewable, fossil fuel, or alternative? correct answers An alternative What is photovoltaic? correct answers Solar energy What is the different between ROI and EROEI? correct answers ROI is return on investments and is monetary while EROEI is energy return on energy investments and relate...

Aquifer correct answersunderground geologic unit that is saturated with water which contains sufficient permeability to yield the water to wells. Unconfined aquifer correct answersWater surface is at atmospheric pressures. Confined aquifer correct answersAquifer that is confined by an impermeable material, such as clay or shale, resulting in the aquifer being under pressure. Permeability correct answersA measure of the ability to transmit fluids based on the material within the aquifer....

How is the percent porosity of an aquifer calculated? - Answer-porosity= volume of pore space/total volume of rock Write Darcy's Law and identify terms. - Answer-Q = KIA where Q= ground water discharge (m3/day) K= hydraulic conductivity (permeability)(m/day) I = hydraulic gradient (ratio)(delta/L) A= cross - sectional area aquifer - Answer-a body of rock or sediment that stores, filters, and transmits water via opening within rock sediment consolidated aquifer - Answer-Develop...
