Illustration of Water cycle or Hydrologic cycle in nature. The image shows snow covered mountains with precipitation falling from the clouds in the form of snow and rain. The melting snow and the rain water is shown as surface runoff water flowing down from the mountains. The water collected in the lake is shown evaporating from the surface and moving upwards and forming clouds. The image also shows the water that is absorbed into the earth and forming ground water. The ground water is shown being taken in by trees and the transpiration from trees is shown going upwards in the form of arrows.
