Natural diversities- Conservation effort across india
Conservation effort across india News about efforts to conserve flora and fauna is often met with cyni cism and despondence in the country. The reactions are not mis. placed considering the multiple threats our ecosystems face from anthropogenic activities: displacement caused by large infrastruc ture projects, effluents and plastic being dumped into our lakes and rivers or the roadkill that takes place every day. A United Nations report in May 2019 named that globally, human pressures may push million species to ex extinction in the next …
Solid waste management
Solid waste management Initial problem in Solid-waste management- Following problems are in front of solid waste management agencies- Large no. of open Waste collecting spots Onsite burning of waste Unscientific Disposal Site Reckless staff With random working sites Lack of public awareness and co-ordination No any strict decision taken against waste generators Lack of garbage transport, Tool and Technology No master plan for waste management Weak connection with large Areas. Key features to reduce solid waste- Publ…
Beauty of Nature
Beauty of Nature Nature points to heart and mind to God the magnificent reaches of Gods universe loudly speak His name everything human have needed to survive, and thrive, was provided by the natural world around us: food, water, medicine, material for shelter and even natural cycle such as climate change nutrients. scientist have come to return such gift 'Ecosystem services'; however the recognition of such services go back thousands of years and perhaps even further. Yet we have so this can disconnect ourselves from …
Mariana Trench
Mariana Trench Some important information about Mariana Trench- The mysterious deep sea. Also known as the challenger deep. It is one of the deepest spot of earth. it is 7 miles(Approx 70,000ft) down from the sea level. Located in the western Pacific east of the Philippines and an average of approximately 124 miles (200 kilometers) east of the Mariana Islands. it is approx 4.375 times deeper than the Mount Everest height. In 2009 united nation protected it and gives permits for research on the monuments inside it. here the pressu…
Thermodynamic properties
Thermodynamic properties 1. Intensive properties - The properties which are independent of mass of the system is called intensive properties. e.g.-press.,temp.,density 2. Extensive properties- The properties which are inependent of mass of the system is called extensive properties. e.g.- Volume, Entropy, Enthalpy path- The locus of series of state through which the system process in going initial state to final state is called path process- The specified path on which the state is change is called path
Einstine theory of mass-energy
Einstein's mass-energy relation The most famous equation in physics is Einstein’s mass-energy equivalence: E = mc^2 E = m c 2 . It says that a stationary object's total energy E E is related to its mass m m by c^2, c 2 , the speed of light squared. The total energy is still conserved. As some energy is released in the form of radiation, the total energy of the massive particles after the interaction must be less. This process can be partially observed during nuclear fission when an atom splits into smaller, lighter nuclei…
Plastic Pollution
Introduction The pollution caused due to plastic materials is plastic pollution. The great achievement of the human being is the development of technology. this technology gives many things to the human being including plastics. plastics become a part of human activity. for example- when you wake up in the morning you use plastic brushes when you go to the kitchen you can find many small containers which are made up of plastics. when you go to the office you can get used of plastics in cars and bushes. in the office, there are many thin…
Ecosystem
Ecosystem term is first proposed by A.G. Tansley in 1935. According to Tansley "Ecosystem is the ecological unit consisting of biotics and abiotic components of the environment in a specific area" Eg.- Grassland ecosystem Forest ecosystem Desert Ecosystem Components of ecosystem There are two components of the ecosystem- Biotic components-All living things available in Ecosystem is biotic components. Abiotic components- other than biotic components are known as Abiotic components. classification of Ecosystem…
Deforestation
Definition Excess cutting of tree forest without plantation is called deforestation. Forest produce vital oxygen and provide homes for people and wildlife. Many of the world’s most threatened and endangered animals live in forests, and 1.6 billion people rely on benefits forests offer, including food, fresh water, clothing, traditional medicine, and shelter. Deforestation is clearing Earth's forests on a massive scale, often resulting in damage to the quality of the l…
Two stroke and four stroke engine
Difference between the two strokes and four stroke engine- Please watch in desktop mode S.No. Four stroke engine Two stroke engine 1. It has one power stroke for every two revolutions of the crankshaft. It has one power stroke for each revolution of the crankshaft. 2. A heavy flywheel is required and the engine runs unbalanced because turning moment on the crankshaft is not even due to one power stroke for every two revolutions of the crankshaft. The lighter flywheel is required and the engine runs balanced because …
Structure of atmosphere
What is the atmosphere? The atmosphere is the mixture of gases and water vapor which surrounds any planet system. E.g. For earth, these gases are oxygen, carbon dioxide, nitrogen and water vapor, etc. The atmosphere is classified into five parts- Troposphere Stratosphere Mesosphere Thermosphere Exosphere* segments of atmosphere Earth's atmosphere is about 300 miles (480 kilometers) thick, but most of it is within 10 miles (16 km) the surface. Air pressure decreases with altitude. At sea level, air pressure is abou…
solid waste management
What is solid waste? Any solid component that is thrown out after use and that materials effects the environmental conditions are known as solid waste. According to Britannica, “Solid-waste management, the collecting, treating, and disposing of solid material that is discarded because it has served its purpose or is no longer useful. Improper disposal of municipal solid waste can create unsanitary conditions, and these conditions in turn can lead to pollution of the environment and to outbreaks of vector-borne disease—that is, diseases s…
