Exam 14: Weathering, karst Landscapes, and Mass Movement

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

Continuing dissolution and collapse may lead to the coalescing of sinkholes to form which feature?

In which climates would rocks experience the highest amounts of chemical decomposition and decay?

If Earth did not experience endogenic processes,which would best describe the landscape?

Physical and chemical weathering processes are not separate-they often operate in concert to decompose and dissolve rock.

Which is the convex upper portion of a typical slope?

Salt-crystal growth (salt weathering)is an example of which weathering process?

The photograph shows an example of which mass movement processes?

List and describe the various classes of mass movement.

Briefly describe chemical weathering,providing examples of several physical weathering processes.

In polar and alpine regions,which slow downslope movement results from thawing and saturation of the upper layer of soil?

Which is weathering that softens and rounds the sharp edges and corners of jointed rock?

Which is a mass of falling and tumbling rock,debris,and soil traveling at a high velocity owing to the presence of ice or water?

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

By definition,a landscape in a state of dynamic equilibrium experiences no change.

A niche in sandstone,such as that in Arizona's Canyon de Chelly,is indicative of which weathering process?

Weathering is not influenced by vegetation.

In 1973,part of the flat ground on which a subdivision was located became saturated and began to flow toward the Saint Lawrence River at speeds of up to 26 km · h-1.The ground that flowed consisted of silts and clays-not large,rocky regolith.What type of mass wasting event was this?

Which is a slow persistent mass movement of surface soil?

Freeze/thaw cycles contribute to soil creep.
