Concept explainers
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?

- The control of water for irrigation and human use was a critical factor in developing all city-states throughout the world.  Today, as the world’s environment changes, water has become a serious concern for billions of people. Very few cultures achieved the level of water control like the Inca and the cultures that preceded the Inca. From the Nasca irrigation system to the cleansing of water in Machu Picchu, the Inca developed water systems from the highest mountains to the coastal deserts. So the question is Explain thoroughly how the Inca Empire and the different techniques they used to control and clean water?arrow_forwardTest Your Understanding 9. Which of the following processes is not directly involved in the hydrologic cycle? (a) transpiration (b) evaporation (c) precipitation (d) nitrification (e) condensationarrow_forwardIn lakes around the world, some have thick deposits of limestone, which is made up of calcium carbonate, and are resistant to the effects of acid rain. What parallels can you draw between these lakes and the smokestack scrubbers being used in coal-powered factories?arrow_forward
- Hello! I have an assignment this week but I don't understand how to create a controlled experiment and can't come up with any ideas yet. The question is the following: What do climate change and ocean acidification have in common? Â Design a controlled experiment to test the hypothesis that water acidification caused by acid rain would inhibit the growth of Acropora, a reef-building coral. Â Thanks in advance!arrow_forwardWater circulation is complex.Arrange five distinctive steps of water that continually cycle around the planet.arrow_forwardIn the water cycle, what happens during evaporation? Group of answer choices a. liquid water changes to water vapor b. water flows over the ground c. water vapor changes to liquid water d. water falls to the ground from cloudsarrow_forward
- which is the currently CO2 content of Earth'satmosphere is approximatelyA. 1%.B. 20%.C. 25 ppm.D. 330 ppm.E. 600 ppm.arrow_forwardAnswer the question Briefly 1.) Is rain water safe to drinks? Why? 2.) Now that we are experiencing global climate change, what do you think will happen to polar caps and glaciers? What will be the effect of these to Islands? 3.) Why are trees needed in the watershed? 4.) Why are dams destructive to the watershed? 5.) What are the worst effect of fertilizers to our water system? 6.) Does mining contribute to watershed? 7.) How does aeration help us improve water quality? 8.) If we build septic tanks, how far should it be from the pump well? Why? 9.) Where do you find radon? 10.) How can be avoid runoff contaminants?arrow_forwardWhy is carbon dioxide, a life sustaining, compound considered pollution and how do scientists know that humans are responsible for the increasing levels of CO2 in the atmosphere and global warming? When does carbon dioxide become a pollutant? Global warming has caused a rise in the world’s oceans. How is this affecting world coastlines? How is this affecting the coastline closest to you? Can you envision some popular tourist locations that might be endangered by a rising ocean? Are “greening” efforts like using biofuels and low-carbon imprint practices too little, too late? Task: Do some research on increasing levels of carbon dioxide in our biosphere and what consequences that will have. Additionally what are some options suggested to help combat this issue?arrow_forward
- Continuous movement of elements and compounds that make up nutrients through air, water, soil, rock, and living organisms.arrow_forwardList two sources of dissolved oxygen in a lake and based on your understanding of those sources, explain how you would expect the amount of dissolved oxygen in a lake to vary between day and nightarrow_forwardStarting with a drop of water in the ocean, describe a full cycle of movement of the water drop through the hydrologic cycle (the water must end up back in the ocean). Through what reservoirs does that water move? What physical forms does the water take (e.g., liquid, solid, gasarrow_forward
