One day a little drop Dolly had a rest with her brothers and sisters on the water-plant in the sea. Suddenly the wind had blew. At that moment the wind had lifted Dolly with her relatives up in the sky. Then Dolly realized that she was laying in a grass. She understood that she was far from her native place.

Описание слайда:

The Term of “Acid Rain” “Acid Rain” is a broad term used to describe several ways that acids fall out of the atmosphere. A more precise term is acid depositions, which has 2 parts: wet and dry. Wet deposition refers to acid rain, fog, and snow. As this acidic water flows over and through the ground, it affects a variety of plants and animals. The strength of the effects depend on many factors, including how acidic the water is, the chemistry and buffering capacity of the soils involved, and the types of fish, trees, and other living things that rely on the water.  Dry deposition refers to acid gases and particles. About half of the acidity in the atmosphere falls back to earth through dry deposition. The wind blows these acidic particles and gases onto buildings, cars, homes, and trees. Dry deposited gases and particles can also be washed from trees and other surfaces by rainstorms. When that happens, the runoff water adds those acids to the acid rain, making the combination more acidic than the falling rain alone.

Описание слайда:

2. How do we measure Acid Rain? Acid rain is measured using a scale called "pH." The lower substance's pH, the more acidic it is. Pure water has a pH of 7.0. Normal rain is slightly acidic because carbon dioxide dissolves into it, so it has a pH of about 5.5. As of the year 2000, the most acidic rain falling in the Unites States has a pH of about 4.3.

Описание слайда:

3. Causes of Acid Rains Acid rain is a uniquely human - related phenomenon. The burning of fossil fuels ( coal and oil ) by power-production companies and industries releases sulfur into the air that combines with oxygen to form sulfur dioxide ( SO2 ). Exhausts from cars cause the formation of nitrogen oxides in the air. From these gases, airborne sulfuric acid ( H2SO4 ) and nitric acid ( HNO3 ) can be formed and be dissolved in the water vapor in the air. Although acid-rain gases may originate in urban areas, they are often carried for hundreds of miles in the atmosphere by winds into rural areas. That is why forests and lakes in the countryside can be harmed by acid rain that originates in cities.

Описание слайда:

5. Effects of Acid Rain The environment can generally adapt to a certain amount of acid rain. Often soil is slightly basic. Because bases counteract acids, these soils tend to balance out some of the acid rain's acidity. But in areas, such as some of the Rocky Mountains and parts of the northwestern and southeastern United States, where limestone does not naturally occur in the soil, acid rain can harm the environment. Some fish and animals, such as frogs, have a hard time adapting to and reproducing in an acidic environment. Many plants, such as evergreen trees, are damaged by acid rain and acid fog. We can seen some of the acid-rain damage to the evergreen forests in the Black Forest of Germany. Much of the Black Forest was indeed black because so much of the green pine needles had been destroyed, leaving only the black trunks and limbs!

Описание слайда:

6. How does acid precipitation affect stone and buildings Acid precipitation affects stone primarily in two ways: dissolution and alteration. When sulfuric, and nitric acids in polluted air react with the calcite in marble and limestone, the calcite dissolves. In exposed areas of buildings and statues, we see roughened surfaces, removal of material, and loss of carved details. Stone surface material may be lost all over or only in spots that are more reactive. Gypsum is white, but the crystals form networks that trap particles of dirt and pollutants, so the crust looks black. Eventually the black crusts blister and spall off, revealing crumbling stone.

7. Conclusion   No, we don't need to start wearing a rainhat. Now, acid rain is not pure acid falling from the sky, but rather it is rainfall or atmospheric moisture that has been mixed with elements and gases that have caused the moisture to become more acidic than normal. Acid Rain: Do we need to start wearing a rainhat ? Hypothesis: Conclusion:
