Geography chapter 13
Chemical weathering is greatest under conditions of
higher rainfall and temperatures
Which of the following is not a type of physical weathering process?
hydrolysis
Which of the following can lead to the slope failure that causes mass movement?
saturation, oversteepening of slopes, earthquakes, and volcanic eruptions
Which of the following is not a class of mass movement?
slip
Inclined surfaces that form the boundaries of landforms are known as
slopes.
Carbonation, in terms of chemical weathering, occurs when
water vapor dissolves carbon dioxide, yielding precipitation that contains carbonic acid.
A slow persistent mass movement of surface soil is called
soil creep.
Plants are important to the development of karst primarily because
they supply organic acids that enhance the dissolution process
All processes that cause reduction and rearrangement of landforms are included in the term
denudation.
When pressure is removed from overlying rock, the pressure of deep burial is relieved, initiating pressure-release jointing. The joints then separate into curved slabs. This is known as
exfoliation.
The fact that water expands as much as 9% of its volume as it freezes is the basis of
frost wedging.
Continuing dissolution and collapse may lead the coalescing of sinkholes to form a
karst valley.
