Question

what is the process by which water vapor turns into liquid water in the atmosphere?
precipitation
sublimation
evaporation
condensation

Explanation:

To solve this, we analyze each term:

• Precipitation: Water falling from atmosphere (rain, snow, etc.).
• Sublimation: Solid to gas (e.g., ice to vapor) without liquid phase.
• Evaporation: Liquid to gas (e.g., water to vapor) at surface.
• Condensation: Gas (water vapor) to liquid (e.g., vapor to liquid water in clouds).

The question asks for water vapor to liquid water in the atmosphere, which matches condensation. Wait, but the options include "Condensation" (the bottom option, though partially visible). Wait, recheck: the process of water vapor turning to liquid water in the atmosphere is condensation. Wait, but the visible options: the last one is "Condensation" (partially shown). Wait, no—wait, the options are Precipitation, Sublimation, Evaporation, Condensation. Wait, the question is "water vapor turns into liquid water in the atmosphere"—that's condensation. But wait, maybe I misread. Wait, no: let's re-express:

• Precipitation: Liquid/solid water falling (after condensation).
• Sublimation: Solid → Gas.
• Evaporation: Liquid → Gas.
• Condensation: Gas → Liquid.

So the correct process is condensation. But in the image, the bottom option is "Condensation" (partially visible). Wait, but maybe the user's image has the options as Precipitation (top), Sublimation, Evaporation, Condensation (bottom). So the correct answer is the bottom option, Condensation. But wait, maybe I made a mistake. Wait, no—condensation is gas (vapor) to liquid. So the correct option is the one labeled "Condensation" (the fourth option, bottom).

Answer:

The bottom option (Condensation)
