Small shallow hollows in rocks produced by wind deflation are called "swirls" or "wind pits." These features are a result of abrasion and erosion caused by wind-blown sand or particles impacting the rock surface over time.
Deflation is when the top layer of fine sediment or soil is picked up by the wind and reveals larger rock pieces underneath. One land feature produced by deflation is call Desert pavement, which is a surface made out of small rocks. Deflation Hollows are Bowl-shaped areas caused by -what else but- deflation.
Lunar hollows are small, shallow, irregularly shaped depressions found on the lunar surface. They are believed to be caused by the collapse of underground lava tubes or voids created by volcanic activity. Lunar hollows are of interest to scientists studying the Moon's geology and potential future exploration.

Hydrogen gas produced by Oxygen generation (electrolysis) is bled overboard as tiny bubbles, through a small manifold on the outer hull. The bubbles are small enough that they can't cause noise, nor be seen at shallow depths.

Deflation is the removal of worn rock by the action of wind carrying sand or small particles that erode the surface of the rock over time.
Cats Sleep in nests and small hollows they find.
Corries or Cirques are bowl like hollows in a mountain range, formed by the action of a small glacier.
