hydrosphere. Water on our planet can be stored in any one of the following major reservoirs: atmosphere‚ oceans‚ lakes‚ rivers‚ soils‚ glaciers‚ snowfields‚ and groundwater. Water moves from one reservoir to another by way of processes like evaporation‚ condensation‚ precipitation‚ deposition‚ runoff‚ infiltration‚ sublimation‚ transpiration‚ melting‚ and groundwater flow. The oceans supply most of the evaporated water found in the atmosphere (“The Water Cycle.”). Of this evaporated water‚ only 91% of it is

Edelman views these concepts and listing examples that are given in the State of the Union it should be evident on how President Trump used these concepts. According to Edelman‚ condensation symbols have been used throughout time to stir the emotions of those listening. Condensation symbols can be almost anything. Most condensation symbols today are short catch phrases such as ‘me too’ or ‘black lives matter’ movements. The use of catch phrases or visual symbols have a way of hitting at our emotions by

journey water takes as it circulates from the land to the sky and back again. When the temperature and atmospheric pressure are right‚ the same droplets of water in clouds from larger droplets and precipitation occurs. The raindrops fall to Earth. Condensation is the opposite of evaporation. It occurs when a gas is changed into a liquid. Evaporation is the process where a liquid‚ in this case water‚ changes from its liquid state to a gaseous state. Clouds are a large collection of very tiny droplets

and always changing forms‚ it can go from a liquid to a solid to a gas and back to a liquid. The water cycle is how we track movement of water above‚ in and on the earth. The water cycle consists of three major processes‚ condensation‚ evaporation and precipitation. Condensation is the process of a gas changing to a liquid‚ water vapor condenses‚ turns into a gas and then clouds form. Two influences of this process are air pressure and the sun. Another process is called evaporation‚ evaporation happens

Melting or the fusion of ice is endothermic‚ the equation for the fusion of ice is or melting is ∆Hfusion. Solidification goes from a liquid state to a solid state making this an exothermic reaction. Vaporization & condensation is from a liquid to a gas causing an endothermic reaction‚ the equation for liquefying or steam is ∆Hvaporization. Condensation is an exothermic reaction because it goes from a
