What are the layers in the three layer hierarchical structure?

The role of evaporation and condensation in the water cycle is They recycle and redistribute the water in an ecosystem. Evaporation is the process of turning of liquid into water vapor. Heat energy makes it possible for water to evaporate and turn it into gas. This or water vapor turns into liquid water in the form of clouds.

This process is called condensation. When the clouds are heavy, it will start to fall as rain. Without evaporation and condensation, water will not be distributed and recycled. If there would be no evaporation and condensation, there will be no clouds meaning rain will not also occur. All the water in the world will not be safe for any organism and might end to extinction.
