Which of the following statements is correct? Region A would receive the most precipitation Region B would receive the most precipitation Regions C would receive the most precipitation Regions A, B, and C would receive about the same amount of precipitation What feature might you expect to see developed in region C? an alluvial fan a delta a submarine fan point bars California imports most of its water supply. What is most of the water used for? agriculture domestic irrigation - lawns industry municipal drinking water Which of the following regions has the highest average annual rainfall? northeast US southeast US southwest US central US The average annual rainfall in Houston, Texas is _______? 10-20 inches US 20-30 inches 30-40 inches greater than 40 inches What river carries the most water _______? Amazon in South America Mississippi in US Amazon in Africa Ganges in Asia Groundwater represents how much of the world's fresh water supply? about 1% about 5% about 20% about 50% Which of the following rocks has the highest permeability? an unfractured shale a cemented sandstones an uncemented sandstone all of these rocks have approximately the same permeability Which of the following materials has the lowest porosity? shale gravel granite sandstone What is the difference between the saturated and the unsaturated zones of ground water? the saturated zone has a higher porosity than the unsaturated zone the saturated zone has a lower porosity than the unsaturated zone the pore spaces in the saturated zone are completely full of water; the pore spaces in the unsaturated zone are not completely full of water. the pore spaces in the saturated zone are not completely full of water; the pore spaces in the unsaturated zone are completely full of water The boundary between the saturated zone and the unsaturated zone is called the _____. water table aquifer aquilude porosity In the diagram above region A is the _______ . discharge zone recharge zone saturated zone unsaturated zone In the diagram above region B is the _______ . discharge zone recharge zone saturated zone unsaturated zone Influent streams are _______ more common in arid regions more common in humid regions only found in areas of permafrost sinkhole Excessive pumping in relation to recharge can cause_______ the water table to decline a cone of depression the well to go dry all of these In what type of rock do most caves form? granite shale limestone sandstone Sinkholes are a possible danger in regions underlain by what type of bedrock? granite sandstone shale limestone Water that is good enough to drink is called ________. potable water groundwater surface water artesian water Which of the following can contaminate an aquifer? landfills agricultural regions gas stations all of these Where Does Deep Groundwater Plot on the Global; Meteoric Water Line Source: https://uh.edu/~jbutler/physical/chap12mult.html Share :
