Q. Which of the following are the depositional landforms formed by Wind?
Ripples
Zeugen
Seif
Yardangs
Loess
Choose the correct answer using the codes given below: Answer:
Only 1, 3 & 5
Notes:
Yardangs are parallel troughs cut into softer rock running in the direction of the wind, separated by ridges. The direction of the yardangs can indicate the direction of the prevailing wind.
A zeugen is a tabular mass of resistant rock, standing prominently in the desert. It is usually composed of alternating layers of hard and soft rocks.
Playa is a flat-bottom depression found in interior desert basins and adjacent to coasts in arid and semiarid regions, periodically covered by water.
Ripples are regular, wavelike undulations lying at right-angles to the prevailing wind direction.
Loess is terrestrial sediment composed largely of windblown silt particles made of quartz. Loess requires three things:
Dunes are collections of loose sand built piecemeal by the wind.
