Pollution is defined as undesirable change in physical‚chemical $ biological changes in our water‚air‚ $ noise. It can be natural or man-maid.the agents that causes such changes are termed as pollutants I INTRODUCTION Pollution‚ contamination of the environment by man-made substances or energy that haveadverse effects on living or non-living matter. This contamination of air‚ water‚ or soil materialsinterferes with human health‚ the quality of life‚ or the natural functioning of ecosystems. Insimple

The Montreal Protocol was an agreement of 46 sovereign states to reduce the production of ozone-harming byproducts and protect the Earth’s natural ozone layer (UNEP). The agreement forced manufacturers to halt the production of goods created with chlorofluorocarbon (CFC)‚ an extremely damaging chemical vastly used at the time. Since its initial reception‚ the Montreal Protocol

In order to better understand our universe we must first understand our planet and planetary system of which we reside. By understanding Earth’s properties we can get a better grasp of the rest of our solar system. Earth is the best studied of all the terrestrial planets and also where

The automobiles run on petrol or diesel‚the automotives burn the fuels to run the automobiles .The burned fuels are released into the environment‚This released smoke or burned fuels are depleting the Ozone layer of the earth.Due to the depletion of Ozone layer ‚ Green house effect is taking place and the earth is getting heated up and burning from inside. The Most important question to be answered in this Era is - What Can You Do to Save Mother Earth ? The answer is simple

How water is purified in water treatment plants Pre-treatment 1. Pumping and containment – The majority of water must be pumped from its source or directed into pipes or holding tanks. To avoid adding contaminants to the water‚ this physical infrastructure must be made from appropriate materials and constructed so that accidental contamination does not occur. 2. Screening (see also screen filter) – The first step in purifying surface water is to remove large debris such as sticks‚ leaves

chimneys design as well planning trees as they provide a good air quality. The air quality is poorer in urban areas than sparely populated areas. B- Ozone layer: Ozone layer is important because it protect earth from the UV radiations coming from upper atmosphere‚ some gazes are harmful for the ozone layer and caused the creation of a hole in that layer‚ these gazes are prohibited in the protocol of Montreal. C-Soil: The soil quality is measured by different criteria most common criteria’s are drainage

the organisms were buried under layer of sediments and the CO2 became “locked up” in carbonate rocks. 3) Green plants evolve over most of the Earth. 4) Green plants removed CO2 from the air and produced O2 by photosynthesis. (oxygen level increased) Phase 3 – Ozone layer allows evolution of complex animals. 1) The built-up of oxygen in the atmosphere allowed more complex organisms to evolve and flourish. 2) The oxygen also created the ozone layer (O3) which blocked harmful rays from

Warming happens naturally however because of the human race we have increased how fast it’s happening. There have been many meetings with other nations to control the amount of carbon-dioxide released. Along with the release of CFC’s that hurt our ozone. The Ozone deflects 99% of the UV rays which cause a variety of disease. We all know that it is bad but because most people don’t know what to do to help their environment. Well it’s the simple things like recycling and reducing your carbon-foot print.

What are the three major layers (zones) found in the ocean? Describe each layer briefly. The three layers of the ocean are the surface layer‚ the thermocline‚ and the deep zone. The surface layer goes up to 100 meters deep and consists of low density‚ warm water. In the thermocline temperatures decrease rapidly as it extends to depths of 1500 meters. The deep
