Exam 10: Weathering, Karst Landscapes, and Mass Movement

Flood control often produces conditions of worse flooding in subsequent high-water events.

If material is to move downslope, it must overcome the force of

The degradation of a landscape by weathering, erosion, and transportation has an ultimate "goal" of reducing the landscape down to

Concrete that is buried below the ground will usually weather faster than that above ground. This is because

After a threshold is crossed, the landscape

In the Northern hemisphere mid-latitudes, slopes that face ________ have more trees on them because ________.

Iron oxidation produces red and yellow stains on rocks.

In most areas, the upper surface of bedrock is partially weathered to broken-up rock called

Nickpoints migrate downstream.

The effect of urbanization on a typical stream hydrograph is to

Which of the following is a type of chemical weathering process?

Which of the following may act as a base level?

A $\underline {\text { landslide } }$ designation is used when substantial amounts of water are saturated in the mass of materials.

Which of the following might be expected to occur in an ash-covered, mountainous volcanic region following a heavy rain?

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 kmph (16 mph). The ground that flowed consisted of silts and clays-not large, rocky regolith. What type of mass wasting event was this?

In reality, a landscape behaves as

Chemical weathering is greatest under conditions of

A central peak, or a dome of a volcanic mountain, generally produces ________ drainage patterns.

The average size of sediment in a natural levee is ________ that found in the surrounding floodplain.
