The purpose of the lesson is to allow students the opportunity to explain how weather and pollutants are related. Acid rain corrodes the outer surface of buildings. Greenhouse gases present into the atmosphere trap these radiations and do not allow the heat to leave. Well, presence of those substances in our atmosphere which are harmful for us is known as pollution. One of the reasons for global warming is green house effect. So, let’s see what is water pollution? So helpful to know what air pollution and everything. 2.

Industries must treat the waste before discharging them into waters. CBSE Class 8 Science Notes Chapter 18 Pollution of Air and Water Air consists of a mixture of gases. All this is leading towards the pollution in the river Ganga. All these have resulted into adverse conditions for the aquatic animals residing in the Ganga. The lesson covers all important questions and NCERT solutions to book questions have also been provided for convenience of the students. The major cause of pollution on earth is air pollution. Industries are supposed to treat the waste produced before discharging it into waters, but quite often the rules are not followed. This process is known as eutrophication. discharged by various industries have lead to many bad effects like impure water, acidity changes in water, etc. . However, an indiscriminate increase for gases can lead to excessive increase in the Earth’s temperature leading to global warming. A tap that drips once every second wastes a few thousand litres of water every year. The rays that come from the Sun consist of visible light, infra red rays and ultra violet rays. This monument is also corroding day by day. We should not use more chlorine tablets than specified. So, the Ganga action plan was not as successful as it was thought.

The roof allows infra red rays to enter but after reflection, they are not allowed to go back. This has led to pollution in Ganga as people use Ganga River’s water for bathing, washing clothes and many other activities that affects the ph of water and makes it contaminated. This bacterium is otherwise found in human intestine. We should replace our vehicle fuel, diesel and petrol by LPG and CNG. The usage of pesticides and weedicides in the field gets mixed with water bodies during rainfall. Bacteria present in the faeces of mammals indicate the quality of water. var now = new Date(); These wastages are thrown out the water bodies, rivers and make the water contaminated. Large quantities of garbage, untreated sewage, dead bodies, and many other harmful things are discharged into the river. POLLUTION OF AIR & WATER 2. 1. 3. The Ganga at Kanpur in Uttar Pradesh (U.P.). 7. CLASS: PRIMARY 5. When there is excess discharge of chemical into the water, this result into excess growth of algae. So we should not create wastage by reducing the uses of goods. Whenever harmful substances such as sewage, toxic chemicals, silt, etc., get mixed with water, the water becomes polluted. Global warming can cause sea levels to rise dramatically. var month = ("0" + (now.getMonth() + 1)).slice(-2); On reaching earth, the infra red rays are reflected back and a portion of it is absorbed by earth’s surface. This in turn causes fishes and aquatic organisms to die. The major pollutants which cause water pollution are : Sewage, Fertilisers, Pesticides and Industrial wastes. A6- Explain circumstances leading to acid rain. Take a plastic bottle and cut it into 2 halves at the centre. But what are they? 5. So, planting more number of trees will reduce the amount of carbon dioxide responsible for Greenhouse Effect. By volume, about 78% of this mixture has nitrogen gas and about 21% is oxygen.
