Exam Questions and CORRECT Answers
Mass wasting, a process that often occurs between weathering and erosion, involves
________.
the chemical dissolution of minerals due to water
the mechanical breakdown of minerals due to exposure to the Sun and atmosphere
the transport of material by water, wind, or ice
the transport of material due to gravity - CORRECT ANSWER✔✔- D
One important relationship between chemical and mechanical weathering is ________.
chemical weathering can produce smaller pieces of rock that can then be modified by
mechanical weathering
mechanical weathering forms more brittle materials that are easily broken down by chemical
weathering.
mechanical weathering can produce smaller pieces of rock that have more surface area for
chemical weathering to work on.
The processes are entirely different and do not influence each other. - CORRECT
ANSWER✔✔- C
All of the following are factors that affect rates of weathering except for ________.
,rock characteristics
surface area
climate
geologic age of earth materials - CORRECT ANSWER✔✔- D
Assume that water filling a crack in a rock undergoes cycles of freezing and melting. Which
of the following statement is true?
Water expands as it melts, causing the crack walls to be pushed apart.
Water shrinks as it freezes, causing the crack walls to be drawn closer together.
Water expands as it freezes, causing the crack walls to be pushed apart.
Water shrinks as it melts, causing the crack walls to be pulled closer together. - CORRECT
ANSWER✔✔- C
Consider a weathered rock or soil particle lying on a slope. How will the energy transfered
from gravitational force pulling the particle downward along the land surface vary with the
inclination of the slope?
It will increase as the slope angle is lessened.
It will decrease as the slope angle is lessened.
It is not affected by the slope angle.
It could increase or decrease as slope angle is lessened, depending on what the slope is made
out of - CORRECT ANSWER✔✔- B
, The primary agent of contact metamorphism is ________.
folding
heat
stress
strain - CORRECT ANSWER✔✔- B
Which of the following is not one of the ways that sedimentary rock can form?
Water evaporates and leaves precipitated chemicals bonded together behind.
An immense amount of pressure placed on top of sediments squeezes water out and forms
chemical bonds between them
Hot fluids permeate between sediments and evaporate, leaving behind residual minerals that
glue the larger sediments together
An immense amount of heat causes the sediments to slightly melt, elemental atoms to align,
and then solidify - CORRECT ANSWER✔✔- D
Which of the following correctly describes why minerals tend to be separated into differential
layers inside of intrusive igneous rock?
Minerals crystalize at different temperatures, when they crystalize these minerals become
more dense then the surrounding molten rock and sink to the bottom of the chamber.
Minerals crystalize at different temperatures, when they crystalize these minerals become
