Explanation:

Question 1

To solve this, we analyze each option:

• Option A (Condensation): Involves gas turning to liquid, not rising. Eliminate.
• Option B (Evaporation): Liquid turns to gas (vapor) and rises, matching Wally's rise.
• Option C (Precipitation): Water falling (rain, snow), not rising. Eliminate.
• Option D (Infiltration): Water soaking into ground, not rising. Eliminate.

We analyze each option:

• Option A: Describes liquid (Wally) turning to gas and rising, which is evaporation.
• Option B: Talks about cooling, related to condensation, not evaporation. Eliminate.
• Option C: Describes precipitation (rain), not evaporation. Eliminate.

Answer:

B. Evaporation
