Each one of us has sometime or the other heard someone advicing not to eat junk food as they are bad for the health. We should always eat healthy food. But what is the difference between junk food and healthy food why is junk food called bad. Have you ever thought about this? As we know that we require balance amount of nutrients in our daily diet. We require some amount of Carbohydrates for energy some amount of fat and also protein for our body building and body repair. Further we also require small quantities of vitamins and minerals added with roughage . The correct amount and proportion of these food nutrients consist the balanced diet.
Secondly we know that excess of anything even if it’s good is bad. Junk food items contain various type of chemical and preservatives. Further they contain an overload of fats and carbohydrates. They also contain a lot of spices and oil. All these things can make us obese. We should avoid junk food like chips pizza burger at all cost. Because various diseases can be caused after consuming junk food. Diabetes obesity are some of the major problems that can be caused due to the excess eating of junk food.
Children should form the habit of eating healthy food since childhood as big Lifestyle changes seldom occur after childhood. The teenage age is very delicate and adolescents tend to indulge in binge eating of junk food which can cause major complication for them in the later life. Therefore it is always advised to avoid junk food as much as possible.

It is because most carbon compounds form covalent bonds and do not have free electrons, as all the electrons are used in making the covalent bonds. Also, carbon compounds do not dissociate into free ions in aqueous solution and therefore are not able to conduct electricity. Therefore they are poor conductors of electricity.

There are various reasons for this :
1.The levels of air pollution in Delhi are very high. Also the industries near taj mahal release toxic fumes and smoke into the air, polluting it even more. Since the air quality is very filthy therefore it has a very negative impact on the marbles of taj mahal.
2.The tiny insects which live in the yamuna river, which itself is very polluted due to the sewage waste which is being dumped in the river, crawl to the taj and their excrement further stains the marble.
3. Also taj mahal is situated beside a polluted river, enveloped by various industries and covered in dust all day long. Therefore all these factors are having a very negative impact on the marble quality of taj mahal and therefore it is changing its natural colour and turning to yellow.

Human beings require some essential components to survive on this planet Earth. This essential components include sunlight, plants ,water, soil and many other things. Plants are one of the main essential requirements human beings. This is due to various reason plants provides us food and the other reason which is the main reason is plants provide us with the life-saving gas oxygen. Without oxygen humans won’t be able to survive on this planet.
Plants produce food through their process of photosynthesis and oxygen gas is released as a by-product of this process. This oxygen gas which is released by plants is inhaled by human beings and other living organisms.
Oxygen that is said to be a life saving gas because it is required in various important processes that is carried out in our body. It is required for respiration in human beings , which helps human beings to extract energy from the food consumed. All the cells in our body require oxygen for producing energy from the food. Oxygen help a body to replenish the old cell and build new cells. Oxygen it is important because it help us to continue our life processes smoothly. Without oxygen life cannot be imagined on planet Earth.
Human beings inhale oxygen with the help of nose which travels through the windpipe and finally reaches lungs. The oxygen in the air is absorbed by the blood and is transported to various parts of the body, so that they can function well

Plaster of Paris is chemically calcium sulphate. So when it comes in contact with moisture it changes into a hard substance called gypsum. This reaction cannot be reversed and therefore it gets wasted. So it is advised to store plaster of Paris in a moisture proof container.

It was launched on 5th September 1920 by the Indian National congress under the guidance and leadership of Mahatma Gandhi. It was a mass mobilization and peaceful protest. Gandhiji travelled across the whole country for about an year to explain his aims and plan to the common people. His main motives where
1.adopting swadeshi habits live weaving
2.preaching swadeshi behavior and
3.Eradication of untouchability and caste differences from the society.
•Some important features of this movement included:
1. It was a peaceful and non violent protest against the British government.
2. People were asked to give up their titles.
3. They were also asked to resign from government jobs.
4. People were expected to use more of swadeshi goods and behaviour and boycott foreign items.
5. People were asked not to serve in the army.
6. The INC mainly demanded swarajya or self-governance.
• Why was non co-operation movement called off?
It was called off by gandhiji in 1922 in the wake of chauri chaura incident in uttar pradesh. In chauri chaura , a mob of villagers had killed 22 policeman in a violent protest. Gandhiji became very sad after this incident.

Balanced diet means eating adequate amounts of various nutrients like fats, carbohydrates, proteins, vitamins and minerals. All of these are required in different quantities.All these nutrients are found in different types of food. Children who don’t eat balanced diet are prone to infections and diseases and they also have less immunity. People also face difficulties like lack of concentration, weakness and fatigue.

The battle of plassey played a very significant role in the entry of the British forces in the history of India.In this battle the nawab of bengal lost to the English army lead by Robert Clive. The nawabs army was very large as compared to that of English but his own people betrayed him.More than half of his army did not participate in the battle. It was after this battle that british took over the administration of India in their hands and the nawab of bengal was merely reduced to a puppet king, who had no power or money but had all the responsibilities of the kingdom. The British forces on the other hand enjoyed all the money and power.
Factors that led to battle of plassey :
1.Internal conspiracies and fights in the court and among the family of the nawab.
2.The arrival of Robert clive strengthened the English army.
3. Courtesan like jagat seth, mir chand, omichand betrayed the nawab.

Oxygen is one of the most elements on the earth atmosphere. It is required for the humans to breathe and without it humans might not even be able to survive. It is one of the life saving gases present on the earth. The main composition of water has oxygen molecule which is needed for human beings for drinking. Oxygen is released through various processes on the earth atmosphere. Plants play a very vital role in the formation of oxygen. Production of oxygen is not possible without plants. Plants produce oxygen through a process known as photosynthesis.
Photosynthesis is a process in which plants use the green chlorophyll present in the leaves to prepare food for itself. Plants also use sunlight water and carbon dioxide in the process. In this process of fusion is released as a byproduct.Oxygen released by the process of photosynthesis is released into the atmosphere with the help of the pores present in leaves.
The plants are the main producer of Oxygen gas in the atmosphere. They breathe in carbon dioxide and release of Oxygen which helps in human survival. Without oxygen humans won’t be able to survive on earth.
The chemical events that occur during photosynthesis are complex. The result is that six carbon dioxide molecules and six water molecules become six glucose molecules and six oxygen molecules. The word “photosynthesis” means “making things with light.
The oxygen produced by The plant has to undergo through a cycle known as Oxygen cycle. The oxygen cycle is a biogeochemical cycle in which the oxygen has to go through various states and phases such as oxides, Ions etc.
Oxygen which is a life saving gas is produced by plants. Therefore we should plant more plants and trees so that the oxygen level of earth never gets depleted.
Oxygen from plants when released into the atmosphere as various uses. Before plants are rightly said as life savior and autotrophs as they provide each organism with food and other crucial things to survive.

Air pollution means the degradation of air quality due to the pollution caused by various man made factors.Air pollution has may harmful side effects as it can impact the life of human beings very greatly. Various causes of air pollution are :
Harmful toxic gases released by various industries.
Emissions from various vehicles. Vehicles are one of the main cause of air pollution.
Burning fossil fuels releases gases and chemicals into the air.
Eruption of volcanoes
Pollen grains
Wildfires
Smog : Smog occurs when emissions from combusting fossil fuels react with sunlight.
Soot, or “particulate matter,” is made up of tiny particles of chemicals, soil, smoke, dust, or allergens, in the form of gas or solids, that are carried in the air.
•Effects of air pollution :
Drastic and long-term health effects from air pollution include heart disease, lung cancer, and respiratory diseases such as emphysema.
Air pollution can also cause long-term damage to people’s nerves, brain, kidneys, liver, and other organs ,damaging them seriously. Some scientists suspect air pollutants cause birth defects in newborns.
Air pollution also has various detrimental effects on environment and our surroundings. Monuments such as Taj Mahal have turned yellow or showed some of the other defects due to air pollution caused by industries surrounding them.
Global warming, climate change, smog effect, acid rain, extinction of animal species etc are some of the other detrimental effects that air pollution produces to the environment.
The constant pollution of the air has very negative effects on nature and on human health. Those long-term and medium-term effects have become problems that are difficult to solve.Both human activity and natural processes can generate air pollution.
• how to reduce air pollution :
1.use public transport and start carpooling.
2.Do not burst crackers.
3.Walk or cycle short distances and avoid using bikes etc.
4. Recycle and reuse
5. Say no to plastic bags.
6.Avoid smoking and prevent forest fires.
7. Use filters in chimneys
8.Treat the industry waste before releasing it in the environment.
9.use fans instead of AC, as they release Cfc’s in the environment.
10.Plant more trees.
Air pollution is a man made phenomenon and it is our responsibility to reduce it. We can do it bta planting more trees and following all the above mentioned steps whole heartedly. Earth is our home and we have to take care of it otherwise it will soon become uninhabitable and human population would perish.

A volcano is an opening or rupture in the earth’s crust through which lava, volcanic ash, and gases escape out of the earth’s crust. Beneath a volcano, liquid magma containing dissolved gases rises through cracks in the Earth’s crust. As the magma rises, pressure decreases, allowing the gases to form bubbles.
Volcanic activities have a profound influence on the Earth’s landforms. Solid liquid or gaseous material may find their way to the surface from some deep-seated Reservoir beneath. Molten magma is mobile rock that forces its way into the plains of weakness of the crust to escape quietly or exclusively to the surface.
The ancient greeks believed that volcanic eruptions occurred when vulcan the God of The Underworld stroked his subterranean furnace beneath the volcano, an island in Sicily from where the present word volcano is derived.
Geologist and volcanologist have confirmed that volcanic activity is closely connected with the Crustal disturbances particularly where there are zones of weakness due to the deep faulting or mountain folding.
As the depth of the earth increases the temperature also increases. The interior of the earth is in semi molten state comprising of solid liquid and gases materials which are very hot and are collectively called magma.
The Magma is very hot and heavily charged with the gases such as carbon dioxide, nitrogen etc. The gas and vapour increases the mobility and explosiveness of the magna which cause the volcanic eruption. These materials are then admitted to the vent of a volcano during the eruption.
Volcanoes are located in a clearly defined pattern around the World and are closely related to the regions that have been intensively folded or faulted. Therefore folding or faulting of region is one of the main reasons that cause the eruption of volcano.
Examples of active volcano which erupted in the recent years are Mount pelee, Mount Krakatau etc.
Different types of volcanoes have different types of lavas. Some have acid lavas while others have basic lavas. This composition of lava determines the amount of damage the volcanic eruption will produce.
Acid lavas are highly viscous and cause less damage whereas basic lavas are the hottest and highly fluid and cause widespread damage to life and property.

Quit India Movement also known as leave India Movement or the August movement was a civil disobedience movement launched by Mahatma Gandhi In 1942.
The quit India movement or “bharat choro andolan” was a movement launched at the Bombay session of the All-India Congress Committee by Mahatma Gandhi on 9 August 1942, during World War II, demanding an end to British rule in India. This movement movement placed the the demand of complete Independence at the top of the agenda of freedom movement. Even though the Britishers said that Independence could only be granted after the war but this moment drove to this point that India could not be ruled without the support of the masses.
On 7 to 8 August 1942, the All India Congress Committee met in Bombay and voted in favour of the ‘Quit India’ resolution. Gandhi called for ‘Do or Die’. The next day, on 9 August 1942, Mahatma Gandhi along with the members of the Congress Working Committee and other Congress leaders were arrested by the British Government under the Defence of India Rules. The Working Committee, the All India Congress Committee and the four Provincial Congress Committees were declared unlawful associations under the Criminal Law Amendment Act of 1908. The assembly of public meetings were prohibited under rule of the Defence of India Rules. The arrest of Gandhi and the Congress leaders led to mass demonstrations throughout India.People protested in large numbers and demanded “poorna swaraj” or complete freedom. Thousands were killed and injured in the wake of the ‘Quit India’ movement. Strikes were called in many places. The British swiftly suppressed many of these demonstrations by mass detentions; more than 100,000 people were imprisoned.
The ‘Quit India’ movement, more than anything, united the Indian people against British rule. Although most demonstrations had been suppressed by 1944, upon his release in 1944 Gandhi continued his resistance and went on a 21-day fast. By the end of the Second World War, Britain’s place in the world had changed dramatically and the demand for independence could no longer be ignored.
The Quit India Movement acted as a binding source for the Indian masses and the Indian masses United against the foreign rule . The Quit India Movement had a great impact and was significant in many ways as the masses lead the protest in the absence of their leader Gandhiji. People were ready to do or die for their country and its freedom. Patriotism was the new flavour of the Indian soil. People gathered in large groups and demonstrated against the British rule and all this led to the freedom of India from the shackles of the British rule.

As we all know that plants are able to make their own food and therefore they are known as autotrophs. This ability of plants to make their own food help sustain living organisms on the planet Earth. The process by which plants make their food is known as photosynthesis. Photosynthesis form and integral part of the function of plants. In this process plants use raw material such as sunlight water and carbon dioxide from the air and chlorophyll pigment present in the leaves of the plant to make their food. Therefore we can conclude that chlorophyll is a very important pigment that help the plants in making their food and without which It wouldn’t be possible for plants to prepare their food. This pigment is present in the leaves of the plant and helps the plant to tap sunlight and use the energy from it.
Chlorophyll is the molecule that absorbs sunlight and uses its energy to synthesise carbohydrates from CO<sub>2</sub> and water.
Does the chlorophyll pigment is very important from living organisms and not only for plant as if plants do not prepare food the humans will also not be able to get food and similarly all the animals will also die of starvation. Since plants form the most integral part of food chain therefore chlorophyll pigment forms one of the most important components of human as well as plant life.
It is because of the chlorophyll pigment that the leaves of the plant look green. The variation in colour is due to different amount of chlorophyll pigment present in the leaves some plants have large amount of chlorophyll in their leaves while other others may have less.
