Answer:
1= Precipitation reactions occur when cations and anions in aqueous solution combine to form an insoluble ionic solid called a precipitate. A precipitate is a solid that forms out of solution.
A common example is that of the mixing of two clear solutions: Silver nitrate (AgNO
3
) and sodium chloride (NaCl):
AgNO
3
(aq)+NaCl(aq)→AgCl(s)↓+NaNO
3
(aq)
2= Snow is made up of one or more tiny ice crystals that come together to form the intricate and unique shapes of a snowflake," says ABC weather specialist and presenter Graham Creed, "Whereas, hail is a frozen raindrop and is generally a lot bigger than a pure crystal of ice."
3= Within a cloud, water droplets condense onto one another, causing the droplets to grow. When these water droplets get too heavy to stay suspended in the cloud, they fall to Earth as rain. ... Water vapor turns into clouds when it cools and condenses—that is, turns back into liquid water or ice.
4= The three types of rainfall include relief, convectional, and frontal rainfall. Relief rainfall is rainfall that occurs when wind blows moist air...
5= Two processes, possibly acting together, can lead to air becoming saturated: cooling the air or adding water vapor to the air. Precipitation forms as smaller droplets coalesce via collision with other rain drops or ice crystals within a cloud. Short, intense periods of rain in scattered locations are called "showers."
6= Acid rain is caused by a chemical reaction that begins when compounds such as sulfur dioxide and oxides of nitrogen are released into the air. These substances can rise very high up into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants called acid rain.
