Multiple-Choice Quiz

Our Multiple-Choice Quiz will test your knowledge of the basic concepts and ideas offered in Chapter 15. By successfully reviewing these concepts, you will reinforce your comprehension of these geographic ideas.

This activity contains 20 questions.

	Which of the following is not an example of a chemical weathering process?   carbonation salt wedging oxidation hydrolysis

	Which of the following sets of conditions is most favorable for chemical weathering?   low moisture and high temperature high moisture and low temperature high moisture and high temperature low moisture and high winds low moisture and low temperature

	Exfoliation is characterized by   biological weathering. frost shattering. the chemical degradation of bedrock. hydrolysis. curved layers peeling away from bedrock.

	What is the difference between a joint and a fault?   Joints show displacement of the rock structure; faults do not. Joints are horizontal cracks, while faults are vertical cracks. Joints are always longer than faults. Faults show displacement of the rock structure; joints do not. None of the above are true.

	Which of the following is the most important mechanical weathering process?   freeze-thaw action of water hydrolysis salt wedging oxidation exfoliation

	Which of the following is not a category of mass wasting?   fall flow creep slip slide

	Solifluction   is gravity-force driven downslope movement of sediment overlying frozen ground. consists of pieces of rock falling downslope. is the rebound shockwave that occurs following large earthquakes. is viscous, water-saturated sediment that flows rapidly downslope in poorly vegetated environments. is an ocean tidal wave generated by large earthquakes.

	Identify the incorrect statement about mass wasting as an agent of denudation.   Mass wasting is more important in desert regions than in humid regions. Mass wasting occurrences are often initiated by tectonic events. Rates of mass wasting tend to increase with increasing water content of Earth materials. Mass wasting rates increase as hillslope angles increase.

	Which of the following is not generally associated with soil creep?   over many years, fence posts and telephone poles begin to tilt downhill the freeze-thaw cycle slowly moves particles downhill very slow downslope movement of the top layer of soil blocks of weathered rock slide downhill on a layer of clay

	Which category of mass wasting is the slowest?   flow slip creep fall slide

	Rock weathering in general is strongest under what climatic conditions?   cold and wet hot and dry cold and dry hot and wet

	The intensity of physical (mechanical) weathering would be greatest in which one of the following environments?   Great Plains prairie grasslands middle-latitude deserts tropical savanna tropical rain forest tundra

	Slumping   is caused by freeze-thaw activity. occurs along a curved failure plane. is almost imperceptable to the human eye. occurs on dry hill slopes. all the above.

	The most important type of mechanical weathering is   salt wedging. carbonic acid action. hydrolysis. oxidation. none of the above.

	Solifluction is a common mass wasting process in   the rain forest. the desert. the short-grass prairie. the tundra. all the above,

	Quickly removing the stress imposed by overlying rock layers could directly cause ___ in bedrock.   chemical weathering exfoliation lithification subsidence calcification

	_____ are a result of grazing animals on slightly unstable slopes.   Terracettes Solifluction lobes Slump scars Joints Hillslope scarps

	When a mineral is oxided the new substance _____ than the original mineral.   is greater in volume is more easily eroded has weaker bonding is all the above is none of the above

	Undercutting a hill slope during road construction could cause _____.   an earthquake creep mudflow solifluction landslide

	Which following process causes metals to rust?   hydration carbonation oxidation hydrolysis frost shattering
