An unconfined aquifer is an aquifer with a permeable water table. A confined aquifer is bounded above and below by less permeable beds of rock, and its water is confined under pressure. Some aquifers are replenished by precipitation; others are not.Water tableInfiltrationLake14.InfiltrationUnconfined aquiferLess permeable material such as clayConfined aquiferConfining impermeable rock layerFig. 13-3, p. 316

22 24. Which of the following human activities contribute to flooding A. UrbanizationB. DeforestationC. OvergrazingD. Draining wetlandsE. All of the above
23 25. 26. Forested Hillside Oxygen released by vegetation Diverse ecological habitatEvapotranspiration25.Trees reduce soil erosion from heavy rain and windAgricultural land26.Figure 13.25Natural capital degradation: hillside before and after deforestation. Once a hillside has been deforested for timber, fuelwood, livestock grazing, or unsustainable farming, water from precipitation rushes down the denuded slopes, erodes precious topsoil, and can increase flooding and pollution in local streams. Such deforestation can also increase landslides and mudflows. A 3,000-year-old Chinese proverb says, “To protect your rivers, protect your mountains.” See an animation based on this figure at CengageNOW. Question: How might a drought in this area make these effects even worse?Tree roots stabilize soilVegetation releases water slowly and reduces floodingForested HillsideFig a, p. 339
