Answer:
The different stages of water cycle such as evaporation, condensation and precipitation helps in the continuous redistribution and replenishment of water on Earth. Due to the Sun's heat, the water from oceans, rivers and lakes evaporates, from trees and plants through transpiration. When water vapour rises up, it cool down and condenses to form clouds and falls back to Earth as rain, snow and hail. This process is called precipitation. The rain refills lakes, oceans, rivers and aquifers, ensuring the continuous availability of water on Earth.
