Chapter 16 Lab Textbook Reading Questions

This landform feature is the last remnant of a mountain peak, meaning is must be a ________________________ .

Inselberg

What is true of arid regions? Choose all that are true.

They can contain large amounts of sand. They are characterized by mostly rocky landscapes. They are found at the north and south polar regions.

By which means does wind erode solid rock?

abrasion

The shape of a sand dune and its position relative to the wind depends on which of the following?

all of the possible answers are correct

In a basin surrounded completely by mountains (like Death Valley), what can streams do?

all of the possible answers are correct.

What might streams in arid regions do?

all of the possible answers are correct.

After exiting the mountain canyon the streams slowed down and deposited alluvium, meaning this feature must be a ______________________________.

alluvial fan

Landforms in arid regions are more than in humid regions because .

angular; soil creep is less common

Limestones are easily eroded in humid regions. In arid regions, limestones

are more resistant and can form cliffs because of the scarcity of water.

Arid landscapes tend to

change more slowly than humid landscapes.

Remnants of highlands nearly covered by a blanket of sediment are called

inselbergs

Physical weathering in arid regions

is slower than in humid regions because some processes are less effective.

To form this sand dune, wind is blowing from ___________ to ___________.

left to right

Which of the following rock types would make a good tombstone in an arid region but not in a humid region?

marble

Chemical weathering in arid regions is

much less effective because there is little water available.

What stage of desert landscape evolution is represented in the photo below? Hint: the flat areas in the foreground consist of thick piles of alluvium leading up to pediments and inselbergs.

stage 3 (relatively old)

In transverse sand dunes,

the gentle side faces the direction from which the wind is blowing.

Wind erosion and deposition are more important landscape forming agents in arid regions than in humid regions because

there is no soil moisture to hold sand grains together at the ground surface.
