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.
