The Effects of Acid Rain Acid rain has a pH value between pH 5.5 and pH 2 – in some cases, the rain is as acidic as vinegar! The acidity of the rain depends upon the amount of acidic gases dissolved in it. Some areas of the country, and even some countries around the world, will have a bigger problem than others. When acid rain reaches streams and lakes, it makes them acidic. This may kill the water life, including any fish. When acid rain falls on the ground, it soaks into the soil and reacts with the minerals in the soil. This may prevent plants from taking up minerals such as iron, zinc and magnesium which they need for healthy growth. As a result, plants and even wellestablished trees may die. When acid rain falls directly onto plants, it may damage new shoots and leaves. This also prevents the plant from growing. When acid rain falls on buildings and other structures it also causes damage. The acid rain reacts with any carbonates contained in the rocks used for building. Acid rain also corrodes metals such as iron, weakening bridges and other large structures. Choose Task A or Task B: A B Choose one of the effects of acid rain listed above, and research it in more detail. When you have researched your chosen effect of acid rain, produce a three-minute talk to tell another person of your age about your findings. Present your talk to your class, or another group of pupils. Produce a leaflet to explain the effects of acid rain. You should consider each of the effects in turn, explaining why it is important that the production of acidic gases should be reduced. [ knowledge, research ]
