Ques: Answer the following question given this paragraph: Figure below shows the role of the atmosphere in the water cycle. Water vapor rises from Earth's surface into the atmosphere. As it rises, it cools. The water vapor may then condense into water droplets and form clouds. If enough water droplets collect in clouds they may fall as rain. This how freshwater gets from the atmosphere back to Earth's surface. Q: What does water vapor in the atmosphere cool and condense into? Choices: - puddles - rain - oceans - clouds A:
Ans:
clouds
