Aeolian landforms are the features that are formed by the action of wind. These landforms are commonly found in arid and semi-arid regions where wind erosion and deposition processes are dominant. Aeolian landforms are shaped by the abrasive action of wind-borne particles such as sand, silt, and clay.


- Sand Dunes: These are mounds or ridges of sand that are formed by wind deposition. They are characterized by their shape and orientation, which are influenced by wind direction and speed.
- Loess Deposits: Loess is a fine-grained sediment that is deposited by the wind. It is usually composed of silt-sized particles and is commonly found in regions with a dry climate.
- Desert Pavements: Desert pavements are flat, rocky surfaces that are formed by the removal of fine-grained particles by wind erosion. They are composed of larger rocks and pebbles that are left behind after the finer particles are blown away.
- Yardangs: Yardangs are elongated, wind-eroded ridges that are typically found in desert regions. They are formed by the selective erosion of softer rocks, leaving behind harder, more resistant rock formations.
- Blowouts: Blowouts are depressions or hollows that are formed by wind erosion. They are usually found in sandy areas and are characterized by their bowl-shaped appearance.


Geography is an important subject for the UPSC Civil Services Examination (CSE). It is included in the Preliminary Examination as well as the Mains Examination. The study of geography helps candidates understand various aspects of the physical and human world, including landforms, climate, population, resources, and more.

The syllabus for geography in UPSC CSE includes topics such as physical geography, human geography, economic geography, environmental geography, and geographical thought. Candidates are required to have a thorough understanding of these topics and their interconnections.

Studying geography for UPSC CSE involves analyzing maps, understanding geographical concepts, and being aware of current affairs related to geography. It is important to develop a holistic approach to the subject and integrate knowledge from various disciplines such as history, economics, and science.

Candidates can refer to various study materials and resources to prepare for geography in UPSC CSE. They can read textbooks, reference books, and online resources to gain a comprehensive understanding of the subject. Additionally, solving previous years' question papers and taking mock tests can help candidates assess their preparation and improve their performance in the examination.

In conclusion, aeolian landforms are important geographical features formed by wind erosion and deposition. Understanding these landforms is essential for candidates preparing for the UPSC CSE examination, as geography is an integral part of the syllabus. By studying geography in depth and keeping up with current affairs, candidates can enhance their chances of success in the examination.
