hydrologic cycle
				   		Continuous circulation of water in its different states (liquid, solid and gaseous) between the oceans, the atmosphere and the Earth’s surface.
				
 
					
					
					
						solar radiation 
						It provides the heat necessary for water to evaporate.
						
						
				  	 
					
						condensation 
						The process by which water vapor is converted, by means of cooling, into liquid or solid water in the form of clouds.
						
						
				  	 
					
						action of wind 
						Driven by winds, clouds fly over the land.
				  	
 
					
						ice 
						Water that accumulates high in the mountains in solid form.
						
						
						
				  	 
					
						underground flow 
						Movement of infiltrated water that joins a watercourse on the surface or flows directly into lakes or the ocean.
				  	
 
					
						ocean 
						Vast body of saltwater covering a large part of the Earth’s surface and separating the continents.
						
						
						
				  	 
					
						precipitation 
						Various forms of water that fall from the atmosphere.
				  	
 
					
						evaporation 
						Conversion, without boiling, of liquid water into water vapor when exposed to heat.
				  	
 
					
						transpiration 
						Phenomenon by which plants discharge water vapor into the atmosphere.
				  	
 
					
						infiltration 
						Water penetrating into the soil through permeable rock.
				  	
 
					
						surface runoff 
						Flow of rainwater or melting snow on the surface of the ground; it produces watercourses.
