ID: B Name: How does water get from the atmosphere into the groundwater system? a. Precipitation falls into rivers and then flows downriver into the groundwater system b. Precipitation falls on the ground and infiltrates the ground surface to the groundwater 20. c. Water from the ocean is sucked up into the groundwater system because of a pressure difference d. Plants secrete water into the groundwater system in a process called evapotranspiration. 21. The greenhouse effect is a. the current increase in global surface temperatures b. the resulht of global warming. c. a climate change hypothesis that is no longer accepted. d. the trapping of reradiated energy by the atmosphere What type of mass movement is an area that shows bowed out tree trunks and misaligned fences? a. rock fall b. mudflow 22. creep d. debris slide Land subsidence is likely when a. groundwater recharge occurs. b. the calcium content of groundwater increases c. the water table rises d. discharge lowers the water table. 23. 24. Which of the following would decrease the resistance force? a lowering the slope angle b. adding a small amount of water chemical weathering of the slope d. adding material to the base of the hil 25. Which types of features would be found in a glacially carved landscape? a. eskers, drumlins, cirques, and kettles e cirques, arêtes, kettles, and tarns b. cirques, arétes, horns, and striations d. drumlins, ground moraines, and arêtes 26. The competence of a mountain river is than that of a river on a floodplain because lower, there are more bouldens a. lower, the gradient is greater c. d. b. higher, the gradient is greater higher, there is more water 27. Sea levelduring glaciation and during interglac iation. cremains constant; decreases decreases; increases a. b. increases; decreases -28. The loss of rain forests would the concentration of greenhouse gasses, leading to an in global atmospheric temperature a. increase; increase c. decrease; increase d. decrease; decrease b. increase; decrease 29. The discharge of a river traveling through a temperate region will typically downstream; the discharge of a river traveling through an arid region will typicallydownstream. a increase; increase b. decrease; decrease c. increase; decrease d. decrease: increaseExplanation / Answer
20) b
ground water recharging occurs through the infiltration of water through permeable soil layers.
21)d
the long wavelength radiations emitted by earth are trapped with in the earths atmosphere and which increases the temperature.
22) c
in the area of creep the tree truncks are found to be in bent form
23)d
when the water table deceases due to the increased discharge land subsidence occurs
24) c
when the rocks along the slope get chemically weathered, their ability to resist the forces decreases and cause sliding.
25) b
glacial erosion form such land scapes, they have high power to cut through the hard rock.
26) b
gradient of a mountain river is high, so the water will have more kinetic energy and so this will be capable of carry heavy rocks than flood plains.
27)a
when the seawater becomes ice, the water level decreases and more continents become exposed of water.
28) a
deforestation increases the amount of carbon dioxide in the atmosphere and increases the temperature.
29) b
