Final answer:
Solar energy is the primary source of water evaporation on Earth's surface, driving key processes in the water cycle.
Explanation:
The source of energy that causes most of the water evaporation on Earth's surface is the solar energy.
Heat from the Sun causes water to evaporate from the surfaces of the oceans, lakes, and land, forming water vapor in the atmosphere. This process is a key component of the water cycle and is primarily driven by solar energy.
Additionally, the Sun also plays a crucial role in driving winds, ocean currents, and various other processes on Earth's surface.
