- Deflation: This involves the lifting and blowing away of loose materials from the ground. Such unconsolidated sands and pebbles may be carried in the air or rolled along the ground depending on the grain size.
- The finer dust and sands may be removed miles away from their place of origin, and be deposited even outside the desert margins. Deflation results in the lowering of the land surface to form large depressions called deflation hollows. The Qattara Depression of the Sahara Desert lies almost 450 feet below sea level.

Deflation is a geological process that involves the erosion and removal of loose particles from the Earth's surface by wind. It is a common phenomenon in arid and semi-arid regions where there is a scarcity of vegetation and little or no rainfall. Let's analyze the given statements to determine their accuracy:
1. This is the sandblasting of Rock surfaces by winds:
This statement is incorrect. The process described in this statement is actually known as abrasion, not deflation. Abrasion is the mechanical wearing down of rock surfaces by the impact of wind-blown particles like sand. It results in the smoothing and polishing of rocks rather than the removal of loose particles. Therefore, statement 1 is incorrect.
2. Deflation results in the lowering of the land surface to form large depressions called deflation hollows:
This statement is correct. Deflation is a process that involves the removal of loose particles like sand, silt, and clay from an area, resulting in the lowering of the land surface. As the wind blows, it picks up and transports these particles, gradually eroding the surface and creating large depressions called deflation hollows. These hollows are typically shallow and wide, and they can vary in size depending on the intensity and duration of the deflation process. Therefore, statement 2 is correct.
Based on the analysis, only statement 2 is correct. Therefore, the correct answer is option 'B' - 2 only.
In summary, deflation is a geological process characterized by the removal of loose particles from the Earth's surface by wind. It leads to the lowering of the land surface and the formation of large depressions called deflation hollows.
