- The sun is the source of energy for physical cycles on earth
- An example of a physical cycle is the water cycle
- Hence, the sun is the source of energy for water cycle on earth

- The sun is the source of energy for water cycle on earth
- Precipitation is a stage in the water cycle process
- So, the sun is the source of energy for evaporation in the water cycle on earth

Hence, the sun is the source of energy for evaporation in the water cycle on earth
What is the primary source of energy that causes evaporation of water from the surface of bodies of water?
- The sun is the source of energy for physical cycles on earth 
- An example of a physical cycle is the water cycle 
- Precipitation is a stage in the water cycle process
