Yardang - Wikipedia
A yardang is a streamlined protuberance carved from bedrock or any consolidated or semiconsolidated material by the dual action of wind abrasion by dust and sand and deflation (the removal of loose material by wind turbulence). [1] .
Yardang | Wind-eroded, Desert Landforms | Britannica
yardang, large area of soft, poorly consolidated rock and bedrock surfaces that have been extensively grooved, fluted, and pitted by wind erosion. The rock is eroded into alternating ridges and furrows essentially parallel to the dominant wind direction.

Yardangs - (Intro to World Geography) - Vocab, Definition
Yardangs are streamlined landforms that are shaped by the erosive forces of wind and typically found in arid or semi-arid environments. They often resemble elongated ridges or hills and are created through the process of aeolian erosion, where wind-carried particles wear away softer rock or sediment while leaving harder materials intact.

Yardangs on Earth and implications to Mars: A review
2020年9月1日 · Earth yardang model is helpful to identify Martian yardang and its related climate. Yardangs, as typical aeolian landforms, are extensively identified in arid/hyper-arid areas on Earth and other terrestrial bodies.
Before ancient Egyptians, nature sculpted sphinxes. Here’s how
2023年11月29日 · Steady winds can carve landforms called yardangs — thought to have inspired the Great Sphinx of Gaza — from featureless blobs, a new study suggests.
Yardangs - Wikenigma
Yardangs are enigmatic wind-parallel ridges found in arid environments. They often form downwind of rocks in sandy environments. They can be unusually stable structures, given their sandy / dusty composition (and the fact that the wind which forms them can also erode them).
Yardangs - (Earth Surface Processes) - Vocab, Definition ... - Fiveable
Yardangs are streamlined landforms that are shaped by wind erosion, commonly found in arid and semi-arid regions. These elongated ridges or hills are formed when wind selectively erodes softer materials while leaving harder materials intact, resulting in distinctive shapes that can often resemble the features of animals or other objects.
Yardang - EPOD - a service of USRA
2004年11月22日 · Yardangs, in spite of their evocative name, are geologic landforms that are of special interest to geologists working on the surface features of Mars. These long ridges are only found in places that have very little rain, a source of sand, and strong prevailing winds.
What is a yardang and how are they produced? | Socratic
2015年1月21日 · A yardang is a sharp irregular ridge of compact sand lying in the direction of the current wind in exposed desert regions. Yardangs are formed by the wind erosion of adjacent material that is less resistant. Much like if you piled feathers on top of rocks and blew on them. The feathers would blow away, but leave the heavier rock shapes behind.
Aeolian (Dunes) Landforms - Geology (U.S. National Park Service)
Yardangs - streamlined ridges of compact sand lying in the direction of the prevailing wind, formed by wind erosion of surrounding material; Deflation Hollows - also called a blowout dune, created when loose surface material is scooped out by the wind, leaving a hollow.
Yardangs: Nature's Wind-Carved Shelters for Bushcraft and Survival
2024年10月20日 · Yardangs are created over thousands of years by wind erosion, which carves out streamlined ridges and grooves in softer sedimentary rock, leaving behind a jagged yet smooth structure that can reach impressive heights and lengths.
Yardangs - (Physical Geography) - Vocab, Definition ... - Fiveable
Yardangs are streamlined landforms that are sculpted by the erosive forces of wind, typically found in arid and semi-arid regions. These formations are characterized by their elongated shape and steep sides, created as wind erodes softer rock layers while leaving harder layers intact.
Yardangs and Rock Pedestals - Desert Landforms
What are Yardangs and Rock Pedestals? Yardangs are low and long ridges found in the desert. They are made of soft rocks, mostly of siltstone and sandstone. Although yardangs are related to rock pedestals or mushroom rocks, they are not the same thing.
Did These Curious Rock Formations Inspire the Great Sphinx?

What are Yardangs? Answer at BYJU’S IAS
A yardang is a fluted aerodynamic feature formed by eolian erosion. In arid regions, layers of hard and soft rocks are aligned vertically. As winds blow, the soft rocks get eroded, while the hard rock formations remain. Some of the abrasion undercuts parts of the rocks, and these formations are called yardangs.

Introduction: Wind-eroded ridges known as yardangs are common in most arid desert regions on Earth. They also have been identified on Venus, Titan, and Mars [1-2]. Among those on Mars, various yardangs exist especially in the Aeolis-Zephyria Planum (AZP) region, west of the Medusae Fossae Formation (MFF).
