THE WATER CYCLE







I.- How do the following atmospheric conditions influence the water cycle? 1.- If the temperature is very high, does evaporation increase or decrease? Why? 2.- If there is a lot of wind, will water evaporate faster or more slowly? 3.- If humidity in the environment is very high and the temperatures high, will there be more or fewer clouds? Why? 4.- In the desert with low humidity and a high temperature, will there be clouds. Why? Why not? II.- What happens to the rain water that filters into the earth?
 * The high temperature makes water become vapour; therefore, when the temperature rises, evaporation increases. Human beings´s perspiration increases too. **
 * The wind makes water vapour evaporate more quickly **
 * When there is a lot of humidity and temperatures are high, ascending currents of hot, wet air are formed. When they cool down in the troposphere, they form clouds. **
 * In the desert there are almost no clouds, because as there is no water for evaporation the air humidity is very low. **
 * The infiltration water can reach the rivers, the lakes and the sea or it may remain in aquifers for centuries **
