Exam 13: Weathering, Karst Landscapes, and Mass Movement

Volcanic ash deposits composed of maficminerals sometimes develop a very distinctive reddish-orange colour after weathering at the surface.This colouration results from the

The steepness of a slope made of loose material is called the

Which type of weathering is primarily found in arid environments?

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

A landslide designation is used when substantial amounts of water are saturated in the mass of materials.

Tower karst and cockpit karst develop in

The balancing act between tectonic uplift and reduction of the landscape by weathering and erosion,and between the resistance of crust materials and the attack of denudation processes,is summarized in the dynamic equilibrium model.

Plants are important to the development of karst primarily because

A mass of regolith and bedrock that is not saturated with moisture is categorized as an earthflow when it moves downslope in mass.

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

A translational slide involves

In the Andes Mountains of South America,entire towns of thousands of people have been buried suddenly when water and loose materials traveled downhill as a viscous fluid.This type of catastrophic event is known as a

The disintegration and dissolving of surface and subsurface rock in place is called

The convex upper portion of a typical slope is called a

All other factors being equal,landscapes of great relief experience

Debris slopes tend to be larger in arid climates than in humid climates.

Cave formations develop from the precipitation of

Physical weathering dominates in warm,wet climates.

All processes that cause reduction and rearrangement of landforms are included in the term

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?
