Reflections on Reading Exploring the Weather

The air is invisible and intangible, but it changes magically every day, thus forming wind, rain, thunder and electricity. Do you know how these weather conditions are formed? Why did the typhoon land and why did the weatherman predict the coming of the storm? When we look at the blue sky, do you know why the sky is blue? The book Exploring the Weather gives you all the answers.

In all kinds of weather, rain is common, but if it is acid rain, how is acid rain formed? Then why is there acid rain? The answer to this question was found in Exploring the Weather.

In fact, rain is originally weakly acidic, because water vapor dissolves carbon dioxide in the air and forms weakly acidic carbonic acid. If the air is polluted by nitrogen oxides or sulfur oxides, the acidity of rainwater will increase. When these oxides are mixed with water vapor, weak nitric acid and weak sulfuric acid are formed. Acid rain can gradually destroy objects made of limestone, because acid can dissolve stones. With vinegar and chalk, you can demonstrate this process.

All you have to do is put a piece of chalk or concrete on the metal tray. Pour some vinegar on the stone, not too much, because this is simulated acid rain pouring on limestone. At this time, the sound of "hissing" began to appear on the head, indicating that the stone was being dissolved! This process releases bubbles of carbon dioxide, just like bubbles in sparkling drinks. You can hear the hiss, but you have to use a magnifying glass to see the foam! Unless your vinegar is sour.

Alas! In fact, acid rain can also lead to death. The acid rain landed in Canada, Norway, Sweden and other northerly areas, causing the greatest harm. The wind blows acid from nearby industrial countries there. In some acid rain areas, the rocks are very hard and there is no lime at all. Acid and lime will become harmless after reaction, but because the rocks there contain no lime, acid rain flows into rivers and lakes, killing all the fish. In many parts of northern Europe, large forests are dying out. This may be the harm caused by acid rain attack, or the air and rain there may be polluted by other things. It seems that we should protect the environment!

After reading this book, Exploring the Weather, I gained a lot, and all the meteorological mysteries in my heart were solved by this book. The experiment inside completely fascinated me, and I learned a lot of meteorological problems while playing. I think you may also have many meteorological mysteries, right? Read this book quickly and uncover the mystery of weather in your heart!
