Types of Hazard Natural Hazards Human Made Hazards Combination or Socionatural Hazards. Precipitation is the result of the natural process in which: The process is driven by the heat of the sun; the hotter it is, the greater the rate of evaporation. Abnormal fluctuations in temperature correspond to abnormal variations in precipitation. Temperature of a body measures the molecular, what are the different of phase of matter. Rising temperatures increase the rate of evaporation, drying out soils as well as adding moisture to the atmosphere and changing precipitation patterns. xb```f``jaa`da@ N da`(A%L`#V 2N[ibv`z`l`Tx`A@D+S.V FF L@Crrhcce:0A@A@ a+cC33PC(tgIF,m\05zU;NuhGvl:ao>VoT5AfkNr!A]]bFM].2R4z\Wp~. 9 Easy April Fools' Pranks for Kids That'll Get Everyone Laughing.
