Which agent of erosion causes the sandblasting of bedrock

Wind

Explanation:

Wind is an agent of erosion which causes the sandblasting of bedrock. Sandblasting is a stream of sand projected by compressed air. It is a high velocity blast of air or steam carrying sand to etch glass or to clean stone or metal surfaces.

In response to rising atmospheric conditions, wind is caused by the movement of gas molecules in the Earth's atmosphere. The winds act like a pneumatic scouring agent and the top layer of fine soil is dislodged and transferred to undesirable places as a result.

Which agent of erosion causes the sandblasting of bedrock

glaciers

wind

running water

wave action

Gravity, water, wind, and glacier are things that can erode material

Sandblasting is process of smoothing and cleaning a hard surface by forcing solid particles across that surface at high speeds using compressed air and  is the most common method used for surface preparation; they can occur naturally, usually as a result of particles blown by wind causing aeolian erosion, or artificially
