1. The three fundamental needs for clouds to take place are as follows:
a. Water vapor must be present in adequate concentrations so that saturation can be attained by certain means.
b. CCN (cloud condensation nuclei) must be there to offer a surface on which water will condense.
c. Cooling procedure is needed to cool the temperature of the air to the dewpoint temperature.
2. Precipitation is the process of the water cycle where, big and heavy droplets of water fall back to the Earth as snow, rain, hail or sleet.
3. Evaporation refers to the procedure of the escape of the molecules of water from the surface of lakes, oceans, and soil.
4. Transpiration is the discharge of water by the plants.
5. The warmer the air is, the more moisture it can withhold.
7. The water molecules in the vapor produce certain tiny constituents of ice, sea salt, dust, and pollution suspended in the atmosphere. These particles are known as condensation nuclei that function as the starting point for the creation of ice crystals and water droplets.
