What term describes the process by which water molecules can pass through materials?

  1. Absorption

  2. Evaporation

  3. Condensation

  4. Deposition

The correct answer is: Deposition

The process by which water molecules can pass through materials is best described by the term absorption. Absorption refers to the ability of a material to take in water or other liquids. When a material absorbs moisture, the water molecules penetrate the substance and become part of it. This can occur in various materials, including soils, fabrics, and construction materials, and is crucial in understanding how moisture interacts with these substances. The other terms listed relate to different processes: evaporation involves the transition of water from a liquid to a gas, condensation refers to the transformation of gas back into liquid, and deposition signifies a direct process where gas changes into a solid without passing through the liquid state.
