A group of students used two plastic bags to model the water cycle. The students placed 100 milliliters of water into each bag and sealed the bags tightly. Then the students placed one bag in a dark closet and the other bag on a windowsill, in a sunny room. After a few hours the students checked the plastic bags. What did the students most likely see when they checked the plastic bags?

• The bag in the windowsill was empty, but the bag in the closet was full.

• The bag in the closet had more condensation than the bag in the windowsill.

• The bag in the closet and the bag in the windowsill both showed equal amounts of evaporation.

• The bag on the windowsill had more condensation than the bag in the closet.

The picture shows a cumulonimbus cloud forming over an ocean. Which statement best explains how the sun and the ocean interact to form a cumulonimbus cloud?

• Heat from the sun warms the ocean causing water to evaporate. The water vapor then condenses to form a cumulonimbus cloud.

• Heat from the sun causes clouds in the area to gather over the ocean and form on large cumulonimbus cloud.

• Light from the sun shines on the ocean, causing water vapor to condense. The water then evaporates to form a cumulonimbus cloud.

• Light from the sun causes ocean water to reflect water vapor in the air and gather over the ocean into a cumulonimbus cloud.
