Dear aspirant !

Hope you are doing great ! Acid rain occurs when water pH value goes down 5.6 .It occur due to chemical reactions between some sulphur oxide and oxygen with water to form sulphuric acid H2SO4. it's affecting our day to day life very badly ,the very bad effect can be seen on taj mahal which is loosing it's whitening day by day and becoming pale yellow ,if you see taj mahal then you will notice that it has become yellowish that is due to acid rain . Also the another bad effect is on the plants. Acid rain removes the minerals and nutrients from soil that is the need of plants to grow

Hope it helps you!

Thank you

Hi,

Acid rain, or acid deposition, is a broad term that includes any form of precipitation with acidic components, such as sulfuric or nitric acid that fall to the ground from the atmosphere. These may be  in wet or dry forms.  This can include rain, snow, fog, hail or even dust that is acidic.

Acid rain results when sulphur dioxide and nitrogen oxides are emitted into atmosphere and transported through air and wind

Acid rain cause harmful effects on living forms , when it enters oceans or rivers aquatic animals due because of high acidic conditions.

Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. These substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.

Acid rain affects nearly everything. Plants, soil, trees, buildings and even statues can be destroyed by the precipitation. The ecological effects of acid rain are most clearly seen in aquatic environments, such as streams, lakes, and marshes where it can be harmful to fish and other wildlife. As it flows through the soil, acidic rain water can leach aluminum from soil clay particles and then flow into streams and lakes. The after effects of acid rain have been found to be very hard on trees. It weakens them by washing away the protective film on leaves, and it stunts growth.

Acid rain describes a form of precipitation that contains high levels of nitric and sulfuric acids. It can also occur in the form of snow, fog, and tiny bits of dry material that settle to Earth. Normal rain is slightly acidic, with a pH of 5.6, while acid rain has ph between 4.2-4.5.the effects of acid rain could be many like climate change, it has major pollutants which are harmful to people on earth. these pollutants damage both the environment and health of people.it also causes some serious problems to aquatic life. Few of them can tolerate but many aquatic life die which eventually causes a disturbance in food chain.it also spoils the soil of the forest which contains essential nutrients, hence no water to plants and trees so it causes problems to forests as well. hence it causes some serious problems .

Hope this helps.

Hi Bharath.

Hope you are doing well  in this current pandemic.

I guess you have taken the xerox copies of the original Hall Ticket. So I suggest you to take the original copy and the xerox copies, so that you can show those to the concerned officers and explain the reason to them.

So carry all the necessary documents with the original and xerox copies of the KCET Examination hall ticket. That would be enough.

You can go through this link to get more information about the KCET Counselling:

If you have any more doubts you can ask.

BEST OF LUCK!!!

Hi aspirant,

Woodland rain forests and trees around the world should be sustainably managed because:

• They provide shelter and foods to the wildlife.
• Trees absorb carbon dioxide as they grow and release oxygen which maintains the air quality level.
• They help us in stabilizing the soil and thus prevents floods and soil erosion to occur.
• They provide us timber for furniture and materials for essential tools.

Hope it helps!!

First identified in 1872 in Sweden and studied in the U.S. beginning in the 1950s, acid rain is precipitation in the form of rain, snow, hail, dew, or fog that transports sulfur and nitrogen compounds from the high atmosphere to the ground. Sulfur dioxide (SO ₂ ) and nitrogen oxides (NO, NO ₂ ) are bi-products from burning fuels in electric utilities and from other industrial and natural sources. These chemicals react with water, oxygen, carbon dioxide, and sunlight in the atmosphere to form sulfuric and nitric acids. The acids reach the ground and change the chemistry within the environment.

The acidity of any solution is determined on the pH scale of 0 to 14. A pH level of 0 to 7 is considered acidic; 7 is neural; and a level above 7 is alkaline. As the pH number decreases, acidity increases. Unopened bottled distilled water has a pH of 7, so it is neutral. In comparison, household ammonia is an alkaline with a pH of 11.5. Milk is slightly acidic with a 6.5 pH, and soft drinks, which contain phosphoric acid, have a 3.1 pH.

DEAR CANDITATE,

Acid rain results when Sulfur dioxide (SO ₂ ) and nitrogen oxides (NO _X ) are emitted into the atmosphere and transported by wind and air currents. The SO ₂ and NO _X react with water, oxygen and other chemicals to form sulfuric and nitric acids. These then mix with water and other materials before falling to the ground. It can have harmful effects on plants, aquatic animals, and infrastructure.

Acid rain, or acid deposition, is a broad term that includes any form of precipitation with acidic components, such as sulfuric or nitric acid that fall to the ground from the atmosphere in wet or dry forms.  This can include rain, snow, fog, hail or even dust that is acidic.

• Burning of fossil fuels to generate electricity.  Two thirds of SO ₂ and one fourth of NO _X in the atmosphere come from electric power generators.
• Vehicles and heavy equipment.
• Manufacturing, oil refineries and other industries.

Winds can blow SO ₂ and NO _X over long distances and across borders making acid rain a problem for everyone and not just those who live close to these sources.

Processes involved in acid deposition (only SO ₂ and NO _x play a significant role in acid.

Hope it is useful.

Hello Candidate,

When a raindrop is falling down from the sky at a constant speed then it refers that its initial and final velocity before hitting the ground at the same so during its motion in the atmosphere it has no relative acceleration in that particle.

So, if we either know the distance travelled by the raindrop for the time taken for it in order to reach a particular height then we can we relate it with the law of motion to find out the other variable quantities.

Hope you found it helpful. If you have any further queries feel free to post it here!!

Hi Aspirant,

Acid rain is a form of precipitation that is acidic in nature and it has elevated levels of Hydrogen Ions.It can have harmful effects on plants, aquatic animals, and infrastructure. Acid rain that seeps into the ground can dissolve nutrients, such as magnesium and calcium, that trees need to be healthy. Acid rain also causes aluminum to be released into the soil, which makes it difficult for trees to take up water.

Hope it helps!!

Hi Vinod,

Acid rain occurred by the chemical reaction which begins when different harmful chemicals such as sulphur dioxide, nitrogen oxides are released into the air. These subjstances rise very high into atmosphere and get mixed with the droplets, and react with water, oxygen and other checmicals by formic acidic pollutants. And when rain occurs, it caries these polltants in itself, so known as acidic rain. One of the most easily visible effect of acidic rain is on the Taj Mahal, the color of its marble ha sbeen changed to yellowish from white due to the acid rain. As acid rain contains many harmful chemicals so its affects forests, freshwater, decreases fertility of soil, kills insects  and aquatic life forms, fades the paint color, causes corrossion of different metals or statues. It also affects human health.

Thankyou!
