Document Summary
Which of the following processes occurs first in the formation of fossil fuels: diagenesis, photosynthesis, burial under low o2 conditions it depends on the type of fossil fuel. After, you have accumulation of remains that undergo burial in low to no oxygen conditions, then diagenesis. Geothermal heat is ubiquitous, and driven mainly by radioactive decay: types, hot geothermal, cold-heat pump source for our energy is hydrothermal circulation. A porous and permeable rock unit that transports water is known as ______: aquifer, aquitard sandstone unit. A sedimentary or rock unit that does not transmit water easily is known as ____: aquifer, aquitard sandstone unit. Groundwater wells are the most widespread water supply: terms, recharge, discharge, water table, aquifer, stream. Groundwater mining is unsustainable: ogallala aquifer, unconfined aquifer rate at which we extract far exceeds rate of recharge, contaminants can also affect groundwater.
