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
