carbonation, in terms of chemical weathering, occurs when

water vapor dissolves carbon dioxide, yielding precipitation that contains carbonic acid

which of the following human activities can contribute to mass movement

any human disturbance of a slope, including road cuts, surface mining, and development

salt-crystal growth (salt weathering ) is prevalent in which climate type

arid

which is the following is not necessary for well-developed karst to develop

arid condition

the fact that water expands as much as 9% of its volume as it freezes is the basis of

frost wedging

chemical weathering is greatest under conditions of

higher rainfall and temperatures

which of the following is not a type of physical weathering process

hydrolysis

Extensive landscapes formed by the dissolution of limestone and other carbonate rock and characterized by pitted, bumpy surface topography, poor surface drainage, and well developed solutions channels are known as

karst topography

continuing dissolution and collapse may lead the coalescing of sinkholes to form a

karst valley

a translational slide involves

movement of surface material along a planar surface

frost wedging is an example of ________ weathering processes

only physical

the type of mass movement in which material moves in a unit along a zone of weakness is

slides

a slow persistent mass movement of surface soil is called

soil creep

the maximum incline at which sediments on a slope can remain at rest before being pulled downward by gravity is known as the

angle of repose

which of the following is not exogenic in nature

tectonic uplift

hydration involves

the addition of water with little chemical change

hyrolysis involves

the chemical reaction of water

the principle that landscape formation is balance between endogenic and exogenic processes is called

the dynamic equilibrium model

________ occurs as rock surfaces heated by the sun during the day expand slightly, and then contract with nighttime cooling

thermal expansion

landscape formation is a balancing act between tectonic uplift and denudation. this figure depicts which of the following

dynamic equilibrium with threshold

a ________ is a type of debris flow associated with volcanic activity

lahar

the downslope movement of a body of material made up of soil, sediment, or rock propelled by the force of gravity is known as

mass movement

which of the following is not a class of mass movement

slip

chemical weathering that softens and rounds the sharp edges and corners of jointed rock is known as

spheroidal weathering

a slope is ________ if its strength exceed denudation processes and ________ if its materials are weaker than denudation processes

stable; unstable

which of the following are examples of dripstones

stalactites

plants are important to the development of karst primarily because

they supply organic acids that enhance the dissolution process

other than the rock itself, the most important chemical substance needed for the majority of weathering processes is

water

the process that breaks down rock at the earths surface through disintegration of rocks into mineral particles or dissolving it into water is known as

weathering

cones and cockpit karst develop in

wet tropical areas

pitted rock surfaces known as tafoni, or honey comb weathering, result from ________ weathering

salt-crystal growth

which of the following can lead to the slope failure that causes mass movement

saturation, over-steepening of slopes, earthquakes, and volcanic eruptions

the dynamic equilibrium model refers to

a balancing act between tectonic uplift and rates of denudation by weathering and erosion in a given landscape

flows involve

a slurry of unconsolidated materials moving downslope

if a material is to move downslope, it must overcome the force of

both friction and inertial resistance

any large cave formed by chemical processes is a

cavern

when rock is broken down and disintegrated in the presence of water and with chemical alterations to the rock, the process in operation is

chemical weathering

all processes that cause reduction and rearrangement of landforms are included in the term of

denudation

rocks of the same composition and structure found in the same area may have weathered at uneven rates due to a variety of factors. this is know as

differential weathering

the uplift of mountains is caused by

endogenic processes

when pressure is removed from overlying rock, the pressure of deep burial is relieved, initiating pressure-releasing jointing. the joints then separate into curved slabs. this is known as

exfoliation

exfoliation is most common in

foliated metamorphic rocks

rust formed by the reaction fo iron and oxygen in the presence of water is an example of

oxidation

the consolidation or unconsolidated materials from which soils develop is known as

parent material

when rock is broken down and disintegrated without any chemical alterations, the process in operation is

physical weathering

when the upper surface of consolidated rock undergoes constant weathering, it creates broken-up rock called

regolith

factors influencing the weathering process include

rock composition and structure, climate, organic processes, and subsurface water

the presence of talus slopes indicates the occurrence of

rockfall

________ may form at the bottom of cockpits and may even be an important cause of cockpit karst topography

sinkholes

the weathering of limestone can create circular depressions known as

sinkholes
