Which one of the following is an Aeolian sedimentary rock?

Correct option is A

Loess is an Aeolian sedimentary rock. Aeolian sedimentary rocks are formed from materials transported and deposited by wind action. Loess is composed of fine, silt-sized particles that are typically derived from glacial or desert regions. Its deposition occurs in large quantities over extensive areas, especially in arid and semi-arid climates.
Information Booster:
· Loess is characterized by its porous and loose structure, making it prone to erosion.
· Loess deposits are prominent in regions like China, the U.S. Midwest, and parts of Europe.
· It is often fertile and supports significant agricultural activity.
· Aeolian processes are most active in arid and semi-arid regions.
· Loess can form steep vertical faces and is highly susceptible to landslides.
Additional Knowledge:
· Shale: Composed mainly of clay minerals; forms in low-energy environments like deep oceans.
· Sandstone: Made primarily of sand-sized particles, indicating a more energetic depositional environment, such as rivers or beaches.
· Moraine: Glacial deposit consisting of unsorted material, ranging from clay to large boulders, accumulated during ice movements.
