Further, when they reach the ground, they are known as snow pellets. Graupel forms from ice-coated snow crystals falling on the surface of the earth. In other words, sleet is partly frozen rain and hail is essentially ice balls. Furthermore, sleet will happen in winter weather conditions. However, hail usually associates with thunderstorms or summer weather conditions. Sleet, Hail, and GraupelĪll these are very similar forms of precipitation. Further, it falls on the earth’s surface in flakes when the ice crystals get too heavy to stay suspended. Water vapor turns into ice crystals upon freezing at the cloud level. The temperatures below freezing from the cloud levels to the ground are advantageous to precipitation in the form of snow. Snow is another most commonly found type of frozen precipitation. This is a form of precipitation originating from condensation in the atmosphere. It happens because the droplets of water get too heavy to stay suspended so they fall to the ground in the form of fog drip. Fog Dripįog is a cloud of water vapor which is condensed and suspended in the air near the earth’s surface level. We also have freezing rain in which the rain droplets go through a cold air’s layer and freezes when comes in contact with the ground. Rain depends on three things which are the temperature in clouds, atmosphere and ground level. For instance, drizzle is referred to as light steady rain.įurther, we have sprinkles which are raindrops falling in fine drops for a short period of time. There are diverse terms used by the meteorologists to define these droplets. These solutions conduct electricity due to the mobility of the positive and negative ions, which are called cations and anions respectively. They can be divided into acids, bases, and salts, because they all give ions when dissolved in water. It comprises of little water droplets that turn heavy enough in the clouds so as to fall on the surface of the earth. Substances that give ions when dissolved in water are called electrolytes. The most common type of precipitation is rain. The types of precipitation are rain, fog drip, snow, sleet, hail, and graupel. In order to understand clearly what is precipitation, we will go through the different types and examples so that students can relate it with real life and get a clearer understanding. Moreover, the other forms like drizzle, sleet and fog drip do not limit to a particular season. On the other hand, the one with summer is rain and hail. The ones which are associated with winter are snow and graupel. Moreover, there are particular types of precipitation which associate with summer and others are winters. When we look at dew, it condenses on objects and fog condenses in the air. It is so because both of these are examples of water condensing. However, we will see that fog and dew do not fall into the category of precipitation. You can consider heavy or light rain as precipitation and even snow, drizzle and hail. Now that we are clear on what is precipitation, let us move on to the different types. In other words, any form of water which falls, whether it is in liquid or frozen form, falls as precipitation only. Precipitation is water that falls back to the surface of the earth upon condensing in the atmosphere. (This is why wax is insoluble in water: it is non-polar, so the wax-wax interactions are weak, but the wax-water interactions are weaker than the water-water interactions.1.4 Questions on Precipitation Definition of Precipitation (Ionic salts are a good example: usually they have strong interactions in the solid and solvated states.) If the interactions in the solid are weak, the compound can still be insoluble in polar solvents if the interactions with the solvent are weaker than the Coulomb interactions of the solvent molecules with other solvent molecules. For instance, if it has very strong interactions between molecules or ions in the solid state, then it won't be very soluble unless the solvation interations are also very strong. Solubility depends on the relative stability of the solid and solvated states for a particular compound. (It's also a little funny because many salts aren't strong electrolytes, so teachers might be telling their students to write an equation that doesn't show what's really happening.) However, it does help show what it means to be a spectator ion, since they are the same on both sides when you write it like this. No real chemist would be likely to do this because it is a nuisance.
