1150 - What is the main process of the water cycle in nature?

The main process of the water cycle is:

  1. Evaporation - The sun heats the water in the ocean, lakes, and rivers, turning it into water vapor that rises into the air.
  2. Condensation - The water vapor in the air cools down, turns back into liquid water, and forms clouds.
  3. Precipitation - When the clouds get too heavy with water, it falls back to the Earth as rain, snow, or hail.
  4. Runoff and Infiltration - The rainwater either flows across the ground (runoff) or soaks into the ground (infiltration), eventually making its way back to the ocean, lakes, and rivers, and starting the cycle again.

That's the main water cycle process in nature.
