Exam 13: Weathering, Karst Landscapes, and Mass Movement

Which of the following is correct?

Which portions of a slope overlap substantially?

In what ways can water be involved in physical and chemical weathering processes?

A landslide differs from a debris avalanche in that

Endogenic forces are responsible for ________ and result from ________.

Movement at the geomorphic threshold signals

If you have ever played on a beach and made a sand castle,you used wet sand rather than dry sand.You did this because the ________ of wet sand is greater than that of dry sand.

First discuss the formation and characteristics of karst.Then examine the various types of karst topography and the conditions necessary for the formation of each.

What is soil creep and what are its causes?

The most common type of mass movement in a moderately sloped and dry environment is soil creep.

Karst topography is formed primarily by

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

Chemical weathering is greatest under conditions of

One side of a sand dune is typically steeper than the other side.The steepest slope is controlled by the angle of repose for sand and most materials,which is about

The presence of talus slopes indicates that ________ occur and that the area near them is ________ for real estate development.

You would expect only slight physical and chemical weathering under conditions of

Differentiate between rockfall,debris avalanche,landslide,mudflow,and soil creep.

The large sheets of rock that break off batholiths,such as Half Dome in Yosemite National Park,develop as a result of

On which part of a slope would rocks tend to fall at the highest speeds?

Describe the forces acting on a slope,and also the various physical aspects of a slope,such as waxing slope and debris slope.
