Environment   Water Water is an abiotic component of the environment which is essential for the survival of life on the earth. It is present on the earth in all three states solid, liquid and gas. It covers about 71% of the earth surface.   Importance of Water It is the water which makes life possible on earth. Without water existence of life was not possible on the earth. Therefore, water is very important for all of us.  
  • Water is essential for the survival of life.
  • Water provides shelter to the large variety of plants and animals.
  • Plants use water for preparing food.
  • Water is essential for germination of seeds and their growth.
  Uses of Water  
  • Water is used for different purposes in our day to day life.
  • Water is used for drinking, bathing, cooking and cleaning clothes.
  • Water is used for irrigation in agriculture.
  • Water is used in the industries for the production of various substances.
  • Water is used for the production of electricity.
  States of Water Water is found on earth in all the three states. Solid: Snow is the solid state of water. When water is cooled, it is converted into ice. This process is known as freezing or solidification. Liquid: When ice is heated, it is converted into water. This process is known as melting. Condensation is the process by which water vapor cooled down to convert into water. Gas: Water vapor is gaseous state of water. When liquid water is heated, it gets convened into water vapor. This process is known as evaporation.   Water Cycle The continuous circulation of water from the earth's surface to atmosphere and from the atmosphere back to the earth is called water cycle. Related image Water Cycle     Due to sunlight water from the different sources converts into water vapor. These water vapors rise up in the atmosphere and condense to water drops forming cloud. Then they return back to the surface of earth in the form of rain.   Sources of Water Oceans, seas, lakes, rivers, ponds, rainwater and ground water are the sources of water. Rain Water: Rainwater is the purest form of water. It collects on the earth in the form of surface water and underground water. Surface Water: Water present on the surface of the earth in the form of oceans, seas, rivers, lakes, ponds and streams is called surface water. Ocean contains almost 97% of water present on the earth. But it is saline therefore it is unfit for drinking. Underground Water: Some of the rainwater seeps through the soil and gathers in the non-porous rocks below. This water is known as underground water.   Conservation of Water As we have studied earlier water is very important for us. So we must conserve water whenever it is possible. Some ways more...

  Essay   Disaster Management Management is directly related to planning about future means, what will be the alternate options if your present plan does not work. Similarly managing the situation for disaster. Disasters are generally very destructive in nature. It results huge loss to life and necessary commodities. If it is a case of flood the basic articles like food, matches, drinking water, medicines become big issues because these things get washed away with the flood. Crops, animals and houses also suffer a big loss. To come to normal situation it takes several years. Earthquake or war with a country pushes the country a decade behind. Earthquake destroys the buildings, roads, powder plants and loss to life is large in numbers. People overcome from financial loss but they can not overcome from emotional loss occurred in these disasters. So, it is the responsibility of Government to take action to ensure for the basic facilities in case of disasters. And also it is the responsibility of a common man to take care of all these things.   Inflation An indirect attack to Indian economy- inflation slows down the growth rate of any economy. As inflation is the flow of money decreases into the market. We know that inflation is directly proportional to purchasing power of rupees. In the last few months inflation cracked some new records. It touched around 12% (11.68%) which was really very high and government was not able to control it. But slowly and gradually it came down. The inflation is said to be good if it is between 4 to 6%. Inflation calculation contains so many commodities which are used in day to day life. The possible factors for the growth of inflation may be American economy, prices of oil, National Stock Exchange of Europe, production-agriculture and also political movement in the country. All these mentioned factors decide the inflation.   Mobile: Need, Fashion Necessity The symbol of status is now the means of communication, a common man is now carrying a mobile phone.

But few handsets which are full of facilities like MP3 ringtone, camera, bluetooth, etc., are symbols of status or way of fashion also.   Time Machine Time keeps changing, everyone know\s this fact but most more...

  Paragraphs   A paragraph is a number of sentences grouped together and relating to one topic, or a group of related sentences that develop a single point.   A Car Accident It is the mad craze for speed that is responsible for many motor accidents. Only last year I witnessed what might have been a fatal accident on the Kashmir road. I was motoring down from Srinagar, and as I was nearing Kohala. I came upon the wreckage of two cars on the road. The smash had been caused, by a car coming down, which swept round a sharp corner at forty miles an hour and crashed into a car coming up. Happily no one was killed; but several were badly injured, and the two cars were wrecked. To drive at such a speed down a twisting mountain road is simply to court disaster.   Republic Day India became a Sovereign Republic on 26th January 1950. On this day our new Constitution prepared by Constitution Committee was introduced. On this day, the government was formed by the people of India according to the new Constitution.
