The model shows where water can be found during different stages of the water cycle. What should be added to the diagram to better explain the water cycle? (5.8B)

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? (5.8B)

• Heat from the sun warms the ocean, causing the 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 one 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 into the air and gather over the ocean into a cumulonimbus cloud.
