Deserts and Winds > Concept #1 Quiz
a. at about the latitude of the equatorial region
b. located at about 30°N and S latitudes
c. in a "rain shadow" on the landward side of high mountains
only b. and c.
all of these
Deserts are located surrounding steppes.
Steppes are located surrounding deserts.
Deserts are semiarid and act as a transition zone between humid and arid regions where steppes are formed.
Steppes are semiarid and act as a transition zone between humid and arid regions where deserts are formed.
Rainshadow deserts occur where air masses descend after first having risen to cross a mountain range.
Despite infrequent rainfall, erosional and depositional features of running water are important in deserts.
Desert landscapes are monotonous, relatively flat areas covered to various depths with sand.
Deserts and dry lands are concentrated in areas of ascending air masses and relatively low atmospheric pressure.
Identify each of the indicated general climatic types (based on aridity) by selecting the correct response.
For each item below, use the pull-down menu to select the letter that labels the correct part of the image.
regional distribution of air and water pressure
global distribution of water and ocean currents
global distribution of air pressure and winds
global distribution of glaciers and ice shelves
The air is less moist on that side.
All the rain is on the ocean side.
Wind blew the moisture away.
Clouds blown in from the ocean don't make it over the mountains.
less than 30% is covered with dunes and drifting sand
wind erosion and deposition are important processes
most desert areas are characterized by descending wind patterns
running water has little effect on shaping the landscape
mid-latitude deserts are found at the foot of large igneous intrusions at continental volcanic arcs
mid-latitude deserts are formed in response to continental rifting
mid-latitude deserts form in rainshadows on the landward side of mountains formed by continental collision
mid-latitude deserts form in humid areas on the ocean side of mountains formed by volcanic activity
