What is accumulation in the water cycle?

Accumulation in the water cycle refers to the process where water gathers in large bodies such as oceans, lakes, reservoirs, and rivers. It is the stage where water that has undergone precipitation collects.

The collected water may remain stored for varying periods, ranging from a few days to thousands of years. Accumulation is a vital part of the water cycle, providing water resources for various purposes, including drinking water, irrigation, and industrial use. It is also essential for supporting aquatic ecosystems.
