Water Cycle
 
This model represents schematically an important natural phenomenon - water cycle. After you press the "Start" button you will observe how sea healing by solar radiation initiates clouds formation from water vapor, followed by sedimentation and water return into seas by rivers. After you switch the model into regime of illustration of pollution of the environment (this may be done by radio-buttons in lower part of the model) you may see that the water may be polluted either as a result of air venting by aggressive compounds during function of plant facilities or by discharge of crude waste water into rivers and other ponds. As usually, the "Start" button serves to terminate process while the Reset" button returns the model into initial state.
