Which of the following is correctly matched?

6: Debris avalanche

Which of the following is false regarding joints?

Joints are small, localized fault planes along which movement occurs.

The rate at which rocks weather depends upon

all of these

In the Andes Mountains of South America, entire towns of thousands of people have been buried suddenly when snow fell from high on a mountain side, melted on impact, and then mixed with loose materials that traveled downhill as a viscous fluid. This type of catastrophic event is known as a

debris avalanche.

All processes that cause the wearing away or rearrangement of landforms are included in the term

denudation.

When rock is broken and disintegrated without dissolving, the process in operation is

physical weathering.

Human-induced mass movements produce a category of processes known as

scarification.

Physical weathering is greatest under conditions of

temperatures that reach below freezing.

An example of chemical weathering is

the limestone formations of Carlsbad Caverns in New Mexico.

A landslide differs from a debris avalanche in that

the materials in a landslide are not saturated with water

The disintegration and dissolving of surface and subsurface rock is called

weathering

Which of the following is true of spheroidal weathering?

It attacks the corners and edges of rocks.

Iron oxidation produces red and yellow stains on rocks

True

Soil creep is a natural process sometimes related to a freeze-thaw cycle of soil moisture.

True

If Earth did not experience endogenic processes, the landscape would

be of very low relief as a result of weathering and erosion in the absence of uplift.

Exfoliation occurs because

overlying rock is removed, thereby allowing the underlying rock mass to expand.

The uplift of mountains is caused by

endogenic processes

The science that specifically studies the origin, evolution, form, and spatial distribution of landforms is

geomorphology.

Chemical weathering is greatest under conditions of

higher mean annual rainfall and temperatures.

Which of the following is a type of chemical weathering process?

hydrolysis
