The phrase "actions on the surface" is correct and usable in written English.
It can be used to describe observable behaviors or activities that are apparent or visible, often implying a lack of deeper significance or complexity.
Example: "The actions on the surface may seem straightforward, but they often mask underlying issues that need to be addressed."
Alternatives: "visible actions" or "superficial behaviors".
The altered blocks also show reduced granular cohesion so that mild mechanical actions on the surfaces result in grain detachments and powdering.
The model parameters of the Edwards Wilkinson equation are estimated from kinetic Monte Carlo simulations and their dependence on the deposition rate is used in the formulation of the predictive controller to predict the influence of the control action on the surface roughness and slope throughout the thin film growth process.
Amorphous silica presence is concentrated on the internal and external surfaces of the uncalcinated husk which may promote a pozzolanic action on the surface of the husk and hence enable its use in lightweight concrete (Jauberthie et al. 2000).
Cernan's last action on the surface of the moon in 1972 was to trace "TDC" — the initials of his then-9-year-old daughter, Teresa Dawn — in the lunar dust.
Sometimes broadcasting is used but this is not as efficient, the plants are loose on the bottom and can be moved by water motion induced by wind action on the surface.
Adding a little "mechanical action" on the surface--that is, rubbing while you rise--can help, but while that works for apples, tomatoes, cucumbers and other relatively smooth foods, you can't exactly massage every single grape or inside a bushy head of broccoli.
The produced ultra-fine surface (~Ra 0.1 µm) demonstrates the progression of the adhesion, the plastic deformation following the fretting and sealing actions on the workpiece surface.
Wave action on the ocean surface would force warm surface water down into the deeper ocean.
Rather than interpreting their actions or words on the surface, highly successful people ask why they are doing that.
However admirable these actions may seem on the surface, they are temporary patches in the holes of a sinking ship.
