SCIENCE, TECHNOLOGY, AND SOCIETY In many countries, irrigation is depleting aquifers to such an extent that land is subsiding, harvests are decreasing, and it is becoming necessary to drill wells deeper. In many cases, the withdrawal of groundwater has now greatly surpassed the aquifers' rates of natural recharge. Discuss the possible consequences of this trend. What can society and science do to help alleviate this growing problem?

- How do you think we might solve the problem of eutrophication in the Chesapeake Bay? Assess several possible solutions, your reasons for believing they might work, and the likely hurdles we might face. Explain who should be responsible for implementing these solutions, and whyarrow_forwardA river reached a flood that was passing through it. At a given instant, the storage of water in the reach was estimated as 20 Ha-m. What would be the storage in the reach after an interval of 3 hours, if the average inflow and outflow during the time period are 15 cubic meter per second and 10 cubic meter per second, respectively?arrow_forwardndustrial effluent from a metal processing factory released Cu into a nearby river without any treatment and causes ecological damage, particularly to the fishes and algae found in the river. a. Analyze FIVE aspects/factors why using either fish or algae has limitations in metal biomonitoring program?arrow_forward
- Humans have constructed millions of dams worldwide to control flooding, generate power and provide water for irrigation. What are three serious negative effects of dams? 2. Discuss the distribution of water on Earth, for example where is most water found, is it saline or fresh, etc…arrow_forwardCASE STUDY CONNECTION California’s governor has put you in charge of water policy for the state. Aquifers beneath the state have been overpumped, and many wells have run dry. Agricultural production in the state is down, and farmers are clamoring for you to do something. Meanwhile, more water is needed for burgeoning urban populations in cities such as Los Angeles and San Francisco. What policies would you consider to restore California’s water supply? Would you try to take steps to increase supply, decrease demand, or both? Explain why you would choose such policies.arrow_forward. You are working at the Loy Farm and are tasked with analyzing water supply for agriculture purposes. Answer the following questions: a) You run an experiment to estimate the water flow rate of the drip irrigation system in the Elon High Tunnel greenhouse. You randomly place 10 small 1-quart paint buckets in the soil along the irrigation system. The table below summarizes the water volume collected in the buckets. The irrigation system was running for 2 hrs. Each bucket has a diameter of 11.2 cm, and volume was measured in milliliters (ml). What is the average drip flow in the irrigation system in inches/hr? (Hint: look up the formula for the area of a circle if you don't already know it).

The soil is prepared to a depth of 24…arrow_forward
- Explain how streams can cleanse themselves andhow these cleansing processes can be overwhelmed.What is wastewater? Describe the state of streampollution in more- and less-developed countries.Give two reasons why lakes cannot cleanse themselves as readily as streams can. Distinguish betweeneutrophication and cultural eutrophication. Listways to prevent or reduce cultural eutrophication.Explain why groundwater cannot cleanse itself verywell. What are the major sources of groundwatercontamination in the United States? List ways to prevent or clean up groundwater contamination. Listsome ways to purify drinking water. Describe the environmental problems caused by the widespread useof bottled water.arrow_forwardWhich of the statements about groundwater is NOT accurate? a. In the United States, groundwater provides 50% of the population with drinking water. b. Groundwaters are being depleted faster than they can be recharged. c. Groundwaters are becoming increasingly polluted. d. Removal of pollutants from groundwaters is easily achieved.arrow_forwardNonearrow_forward
- 1) dissolved inorganic carbon such as bicarbonate, is plentiful in the surface ocean. a- In one sentence, what is the biological pump? b- What must happen for dissolved organic carbon to get exported to the deep ocean via the biological pump? Describe at least 2 stepsarrow_forwardPhosphorus immobilization occurs when: O a plant absorbs phosphorus from the soil, and converts it into ATP phosphate rich rock undergoes weathering, releasing biologically-available phosphorus into the environment O a coyote dies, and as it decomposes, it releases phosphorus back into the environmentarrow_forwardWhich of the following water sources will most likely have the highest amount of dissolved oxygen? O a wetland on a sunny, hot day a warm pond after an algal bloom O a cold, fast-moving mountain stream O a shallow pond with high turbidityarrow_forward
