Class 8 Science- Effects of air pollution and water pollution

Effects of Air Pollution

Global Warming– Increase in the amount of carbon dioxide and certain other gases in the atmosphere are responsible for a phenomenon called Global Warming.
Depletion of Ozone Layer -Everyone is well versed with Ozone Layer. It is a layer of the atmosphere which protects both plant and animal life on the earth by absorbing harmful ultraviolet radiation of the sun, which may cause skin cancer. Freon’s are responsible for the depletion of the ozone layer.
Effects on the plant: – Air pollution causes the long lasting and the harmful effects on the growth and development of plants. Few of them are listed as below:-

Photochemical smog forms a layer on leaves and along with dust blocks the sunlight from being absorbed by the leaf surface, this layer blocks the absorption of carbon dioxide by the leaves and also affects the functioning of stomata, thereby reducing the rate of photosynthesis.
Acid rain damages the plants and also causes the premature leaf fall.

Acid rain– When an air pollutant such as oxides of sulphur and nitrogen reacts with oxygen and water vapor of the atmosphere, they eventually form dilute solutions of sulphuric acid and nitric acid. Those acid mixes with rainwater and comes down usually in the form of acid rain. Acid forming gases and acid rain causes the below effect:-

Destruction of vegetarian due to acidification of soil.
Accelerated leaching of rocks and soils.
The decay of limestone, marble and other building materials.
Effect the human respiratory system.

Magnetic and non-magnetic material Class 6 Science

Magnetic and non-magnetic material Class 6 Science A magnet is a substance that is drawn to certain magnetic materials like iron, cobalt, and nickel. Magnets have the ability to draw iron to them. Natural magnets are rocks that naturally draw iron. Non-magnetic materials include things like wood, rubber, coins, feathers, leather, etc. that are not drawn to iron. Magnet characteristics It pulls magnetic materials, such as iron. The magnet's two ends are referred to as its poles. The magnet's diametrically opposed poles are drawn together. Heating, hammering, or dropping causes it to lose its characteristics. On the basis of properties types of Magnets Temporary magnets are those magnets that are magnetic for only a little duration. Typically, iron, cobalt, or nickel are used to make them. When they are close to the powerful magnet, they act like a magnet. When they are yanked away from the powerful magnet, they stop being magnetic. Permanent magnets are magnets that have magne...

What are Noble Gases? Example and noble gases name

What are Noble Gases? Example and noble gases name Noble Gases Noble gases, sometimes known as inert gases or erosions, are part of the modern periodic table's 18th group. This group is made up of the following individuals: Helium is a kind of gas (He) Neon (Ne) Argon is a gas (Ar) Krypton (Kr) Xenon is a kind of xenon gas (Xe) Radon is a gas that can cause cancer (Rn) Noble gases exist in a gaseous state under typical temperature and pressure conditions. Because all noble gases have stable electronic structures, they have very little chemical reactivity. They are monoatomic gases that do not readily form molecules. 'ns2np6' represents the basic electrical configuration of noble gases. As a result, noble gases' outermost valence shells can be deemed 'complete.' The chemical inertness of the group of 18 elements is due to this. Because of the stability of certain elements, these gases form a group. These stable elements' crusts are totally filled.
