Exam 13: Weathering and Mass Wasting

Fractures in rocks where there is no relative movement are referred to as _____________.

The sorting of surface pebbles and cobbles on slopes in periglacial regions results in:

Landslides can be responsible for the formation of

Which of the following processes could result in an induced earthflow?

Accumulations of regolith at the foot of a slope are called ____________ .

Human activities can _____________ mass wasting in forms ranging from mudflow and earthflow to landslide.

Mass wasting in which water saturated soil and regolith slowly flows downhill is referred to as an earthflow.

The strata covering resources such as coal that is being removed in strip mining is known as the:

____________ is the general term applied to the combined action of all processes that cause rock to disintegrate physically and decompose chemically because of exposure near the earth's surface.

______________ occurs when the stress created by the freezing of water into ice becomes greater than the cohesive strength of the rock containing it.

Using an annotated diagram,describe a vegetation slope and the factors that might contribute to mass wasting.

Landslides are triggered by heavy rains rather than earthquakes or sudden rock failures.

Alpine permafrost is restricted to elevations at which the mean annual temperature is below freezing.

Compare and contrast the features of weathering associated with moist and arid climates.

Water is a major agent of weathering because of its property that,when it freezes,it decreases in density and _______________.

Continuous permafrost and sporadic permafrost occur at the highest latitudes of periglacial regions.

The extremely slow down-hill movement of soil and regolith is called _______________.

Thermokarst is characterized by which of the following features?

The permafrost table ________________.

Compare and contrast the features of natural mass wasting to the impacts of scarification.
