3. Heat from the Sun drives evaporation, turning water on Earth's surface into water vapor.
Explanation:
Water cycle starts with evaporation of water from water bodies which includes transition of water into water vapor by heat of sunlight. The water vapor rises up in the sky and gets condensed to form clouds. This is followed by precipitation and collection of water into the water bodies again through surface run off. Hence, the very first step of water cycle, that is, evaporation is driven by energy from Sun.
