Questions Related to man made materials
Which material is responsible for the cause of animal death?
-
Plastic
-
Sand
-
Plants
-
None of the above
Most of the wandering animals eat plastic bags which take thousand of year to decompose and remain in the body of animals and become cause of death.
Which of the following materials is responsible for the cause of animal death?
-
Paper
-
Plastic
-
Chemicals
-
None of the above
Which of the following statement is true about non-biodegradable materials?
-
They are safe for environment
-
The wastes are made up of synthetic material
-
They can be constantly reused
-
The wastes are made up of natural ingredients
Non-biodegradable materials are those which do not decompose by natural processes. Non-biodegradable materials are generally synthetic polymers. They are not safe for the environment. Natural fibres degrade very easily in nature. However, non-biodegradable materials are made up of synthetic materials which are not broken down by micro-organisms.
Which of the following item cannot be recycled?
-
Plastic milk bottles
-
Plastic food trays
-
CD/DVD cases
-
Plastic cups
Plastic containers are relatively dense and compact which enables them to be easily sorted mechanically, into the different types of plastics. Plastic film and bags are not easily mechanically sorted making them very costly to sort. Also, recycling such plastic is an expensive process.
Examples of non-biodegradable is/are :
-
Tyre
-
Plastic
-
Electronic components
-
All of these
Non biodegradable waste is waste that does not break down into natural components and exists in the environment for a long time. Examples would be tyres, plastics, electronic components, metals etc
______ is an example of biodegradable .
-
Thermal power plants
-
Fertilizer industries
-
Steel plants
-
Cotton mills
Cotton mills (cotton clothes) is an example of biodegradable.
Other biodegradable materials are paper, wood, peels of vegetable and fruits, leftover foodstuff, woollen clothes etc.
Non-biodegradable materials are plastic bags, tin, aluminium, and other metal cans.
Note : Biodegradable waste consists of plant and animal waste that is broken down by other living organism. It is produced in industries like cotton mills, food processing units, paper mills and textile factories.
_____ waste products can also be called green waste, food waste, or organic waste.
-
Biodegradable
-
Non-Biodegradable
-
Chemidegradable
-
Physidegradable
Biodegradable waste consists of plant and animal waste that is broken down by other living organism, substances that are broken down by biological processes are said to be biodegradable. Biodegradable waste products can also be called green waste, food waste, or organic waste.
Burning of plastic causes :
-
water pollution
-
air pollution
-
sound pollution
-
All of the above
Plastics is burnt which releases toxic gases like Dioxins, Furans, Mercury and Polychlorinated Biphenyls into the atmosphere. Further, burning of Poly Vinyl Chloride liberates hazardous halogens and pollutes the air, the impact of which is climate change. The toxic substances thus released are posing a threat to vegetation, human and animal health and environment as a whole. These gases cause air pollution only.
Disposable plastic plates should not be used because:
-
They are made of materials with light weight
-
They are made of toxic materials
-
They are made of biodegradable materials
-
They are made of non-biodegradable materials
Disposable plastic plates should not be used because its waste is non-biodegradable and cannot be broken down into its base compounds by micro-organisms, air, moisture or soil in a reasonable amount of time. Non-biodegradable waste is an environmental concern, as it threatens to overwhelm landfills and create disposal problems.
Hence, the correct option is $D$
Non-biodegradable substance releases harmful gases when burnt.
-
True
-
False
Non-biodegradable products include plastic products, metal products, construction waste, electronics etc. Non-biodegradable products are items that cannot decay or be broken down by living organisms. The bio-degradable substances leach out toxic chemicals when they are burnt and are harmful to health.
