The physical removal of material by mobile agents such as water, wind, or ice is called:

The transfer of rock and soil downslope under the influence of gravity is called:

Water works its way into cracks or voids in rock, then freezes and expands, enlarging the openings. After many freeze-thaw cycles, the rock is broken into pieces. A process called:

______________is the gradual rounding of the edges and corners of angular blocks due to their greater surface area.

Which of these is not an external process:

As water freezes its volume:

Where would frost wedging be the most common:

Which of the following describes the role salt plays in weathering rock:

Why do plutons undergo sheeting when they are uplifted?

Identify the type of weathering depicted:

Which of the following is the most important chemical weathering agent:

Where does most of the sand on beaches come from:

Identify the type of weathering depicted:

Which of the following tombstones is most likely made of marble?

The two types of weathering are:

The optimum environment for chemical weathering is a combination of:

______________refers to the downslope movement of rock, regolith, and soil under the direct influence of gravity.

_____________is the steepest angle at which material (unconsolidated granular particles) remain stable. The angle varies from 25 to 40 degrees.

______________refers to the downward sliding of a mass of rock or unconsolidated material moving as a unit along a curved surface.

_____________frequently occur in high mountain areas such as the Andes, Alps, and Canadian Rockies. They are sudden and rapid movements that happen when detached segments of bedrock break loose and slide downslope.

_____________is a relatively rapid type of mass wasting that involves a flow of soil and regolith containing a large amount of water.

Debris flows composed of mostly volcanic materials on the flanks of volcanoes are called:

___________most often form on hillsides in humid areas during times of heavy precipitation or snowmelt.

____________is a type of mass wasting that involves the gradual downhill movement of soil and regolith due to the alternate expansion and contraction of surface material caused by freezing and thawing or wetting and drying.

When soil is saturated with water, the soggy mass may flow downslope at a rate of a few millimeters or a few centimeters per day or per year. It is common in regions underlain by permafrost. Such a process is called:

_____________refers to the permanently frozen ground that occurs in Earth's harsh tundra and ice-cap climates.

The force that controls mass wasting is:

Which of the following is a control/trigger of mass wasting:

Mass wasting processes are classified by:

Which of the following are types of motion associated with mass wasting:
