Answer:
Precipitation and runoff
Step-by-step explanation:
The water cycle is made up of numerous different processes, with each one either producing more water or getting rid of water.
Two processes that contribute more water are precipitation and runoff. Precipitation is when any form of water falls from the atmosphere to the Earth. This can be rain, snow, sleet, hail, etc. Runoff is when water from nearby fields or mountains runs down the slopes and collects in a flatter space. Together, precipitation and runoff will create a lake.
