Review for Semester Final Exam Day 2 Items 18 - 34
18 What type of weathering usually takes place in a rock after a series of freezing and thawing events? frost wedging
19 Define the term “mass wasting.” the process responsible for moving material downslope without the direct aid of running water, wind, or ice.
20 List three factors that can increase the rate of soil erosion. removing vegetation steep slopes heavy rainfall
21 In areas where unconsolidated materials are saturated with water, earthquakes can turn stable soil into a fluid during a phenomenon called ________________________. liquefaction
22 List two factors that cause sea levels to rise and two factors that cause sea levels to drop. Sea level drops when water is stored in expanding ice sheets and continental glaciers, or when rates of evaporation increase. Sea level rises when ice sheets and continental glaciers melt, or when rates of precipitation increase.
23 Draw a picture illustrating the major steps in the water cycle.
24 List three factors that influence stream velocity. channel size and shape laminar flow (when a fluid flows in parallel layers, with no disruption between the layers) gradient
25 What is the world’s longest river, and what is the world’s largest river in terms of discharge? The Nile is the world’s longest river. The Amazon is the largest river in terms of discharge.
26 At a bend in a river, where does most of the river bank erosion take place? on the outside of the bend
27 What is an “oxbow lake?” an abandoned, cutoff, meander loop

29 List some characteristics of wide streams and valleys. natural levees; broad floodplains
30 What is the single most important erosional agent on Earth? running water
31 Explain the process that causes a geyser to erupt. With a slight reduction in pressure, water in a saturated, natural conduit suddenly boils, sending a plume of steam and hot water into the air above the vent.
32 In what type of rock do caves and caverns normally form? limestone
33 Identify the locations of world's two largest ice sheets? Which is the larger? Antarctica is the largest, with Greenland second
34 List five facts common to all glaciers. originate on land show evidence of past or present flow form from the recrystallization of snow are found in cooler climates have a high light reflectivity.
