Question

question: liquids form a flat or slightly curved upper surface when acted upon by ___. answer input spelling counts but capitalization doesnt.

Explanation:

Liquids form a flat or slightly curved (meniscus) upper - surface due to surface tension and the balance of forces at the liquid - air interface. Gravity also plays a role in determining the overall shape of the liquid surface. Surface tension causes the liquid to minimize its surface area, and gravity acts on the mass of the liquid.

Answer:

gravity and surface tension
