Our Environment Class 10 all Definition
All our Dear CBSE Champs, Here we Net Ex. have included Our Environment Class 10 all Definition. All the given definition are important for this year board exam.
- Wild life: The wild life can be defined as an animals or birds which cannot be domesticate by humans. The wild animals include tiger, lion, leopard, fox, wolf, Rhino, deer, zebra, Giraffe are some examples of wild animals, those of wild birds are eagle, swan, duck, ostrich, pigeon, crow, humming bird etc.
- Wild life importance: Wild life can be find any where like in forest, water, desert, grasslands, sanctuary etc. The wild life has much importance in environment. They maintain the food chain and food web of ecosystem. Most of the wild animals are in danger now due global warming, urbanization, trees cutting, and influence of human. Many wild animals are now counted in endangered list due to scarcity of water and food.
- Endangered animals: The term Endangered means the animals who are at the verge of extinction or very low in number are called as endangered animals if they are not conserved their species will be extincted.
- Conservation of forest : Conservation of forest and wild life can be defined as preservation and protection of wild life by providing optimum conditions which are essential for their life. The optimum conditions can be either natural or artificial, to save the life of endangered animals or plants.
- In-situ conservation: In- situ conservation can be termed as the preservation or protection of wildlife under natural conditions, conserve or protect the particular species in their habitat. It is 1st approach because any species can live better in their own habitat. It is protected within the habitat.
- Sanctuary: In one particular area if one species is important but the only particular species is protected. Sanctuary are made for particular species.
- National park: In a particular area or called as ecosystem which contains producers, herbivores and carnivores, then to protect a complete area or an ecosystem called as national park.
- Biosphere reserves: If any ecosystem is very beneficial or having rich sources then such area called biosphere reserve. In which center area called as core area, in which no activity is allowed. Surrounding the core area called as buffer zone 1 in which tourism, research and education is allowed. Surrounding the buffer zone 1 next area is called buffer zone 2 in which people can live.
- Ex-situ conservation: Ex situ conservation can be termed as the preservation or protection of an organism is not enough in natural habitat under such conditions the species kept out of natural habitat or artificial habitat called ex-situ conservation. It can be divided into 4 types such as botanical garden, zoological garden, cryopreservation and wildlife safari.
- Botanical garden: Botanical garden can be understood by the way where the plant specimen are collected and preserve by giving them artificial environment and protect the endangered plants.
- Zoological garden: The zoological garden as the name itself suggest all the wild animals those have not suitable condition in natural habitat are kept in zoological garden.
- Cryopreservation: It can be termed as storage and preservation of cells which are aim to grow are grown via the cryopreservation method.
- Wildlife safari: The animals live in all the artificial condition and it is the main attraction for tourist so without disturbing the animals, tourist can visit called as wildlife safari.
- Pollution: Pollution can be defined as the disturbance in the normal process of environment due to presence of contaminants, the environment get polluted called as pollution. There are basically 3 types of pollution such as water pollution, air pollution and noise pollution. Here we’re mainly concern with water pollution.
- Water pollution: Water pollution can be defined as the water which is not fit to drink. In which contamination is present. The contamination can be of any micro-organisms such as bacteria, viruses or fungus or the contamination due to any chemicals or mechanical factors can be there. The water contamination is now a days major problem facing world. There are various major sources of water contamination such as the water released through laboratories, industries, domestic or agricultural water.
- Sewage: Sewage it can be termed as the water which is released from industries, domestic and from household work. This type of water may contain pollutants as well as microorganisms. Such kind of sewage is directly dumped into the water bodies such as river, pond etc. It can be harmful to the aquatic life such as fishes, aquatic plants etc.
- Accidental oil leakage: The most of the times when oil is transporting via ocean, sea, then the accidental oil leakage can occur. Oil can never mixed with water so the uniform layer of oil forms on the surface of water body and this causes decrease in concentration of oxygen in the water. The depletion in concentration of oxygen leads to fish kill condition in water body.
- Agriculture: The water released from farms, agricultural area is directly release into river, ponds etc and this water contains insecticides, pesticides which can be harmful to living organisms. Under such condition the released water must be treated before dumped into river or any type of water body.
- Radioactive substances: The substances which are heavy in their action and toxic to environment. The discharge of such radioactive metals into water can spoil the water body and the health of aquatic organisms. Because aquatic organisms cannot tolerate the high range of heavy metals.
- Coal: Coal can be defined as the natural and non-renewable source also called as fossil fuel which is formed due to heating activity. It is made up of mainly carbon but also contains hydrogen, sulphur etc.
- Solid coal: Solid coal called as coke. It is formed when heat gets stop and the remaining black part called as solid coal. It is mainly useful to make various kinds of metals and especially iron.
- Liquid coal: Liquid coal is formed when there is extensive heating to a coke, and the liquid form is called as tar, which is used to make roads. It is also useful in making perfumes, drugs and dyes.
- Gas coal: It is formed when liquid coal is heated to 100 C then the fumes of gas are called as gas coal. It is useful in making fuel and in industries.
- Petroleum :Petroleum can be defined as mixture of hydrocarbon or also called as mineral oil or crude oil which is obtained from underground earth, is usually use to make the chemicals, plastic, petrol and other complex compounds. It is also called as black gold according to scientist.
