What is the water cycle?

• The process of water evaporating from the Earth's surface and condensing in the atmosphere, then falling back to the surface as precipitation.

• The process of water freezing and melting in the Earth's polar regions.

• The process of water being absorbed by plants and released through transpiration.

• The process of water being stored in underground aquifers.
