Chapter 13 Review
Water content in the slope material is highest during which of the following types of mass movement?
mudflow
Exfoliation occurs because
overlaying rock is removed, thereby allowing the underlying rock mass to expand and fracture
Uplift of the landscape creates __________ energy, which is converted to __________ energy when materials begin to move downslope.
potential; kinetic
In most areas, the upper surface of bedrock is partially weathered to broken-up rock called
regolith
Which of the following is a typical karst landscape feature?
sinkholes
A slow, persistent mass movement of surface soil is called
soil creep
All processes that cause reduction and rearrangement of landforms are included in the term
denudation
Delicate Arch in Utah is an example of
differential weathering
On which part of a slope would rocks tend to fall at the highest speed?
free face
Which of the following is true of spheroidal weathering?
It attacks the corners and edges of rocks
After a geomorphic threshold is crossed, the landscape:
adjusts to a new equilibrium condition
The dynamic equilibrium model refers to
a balancing act between tectonic uplift and rates of denudation by weathering and erosion in a given landscape
