What substance or material that causes pollution
Non-biodegradable material is in-organic or man-made matter that will not decompose. Any material that is non-biodegradable does not decay or breakdown into simpler forms of matter.This means that when disposed it, nature cannot reuse these material to fuel and it will remain as pollution in the environment.EXAMPLE OF NON-BIODEGRADABLEplastics (polyethylene, nylon, rayon, polyester, lexan, PVC (polyvinyl chloride), dacron).metals (iron, platinum, steel, tin, aluminum, lead, silver, gold, mercury, arsenic, bismuth, zinc, chromium...),ceramics (carbon fiber, fiberglass, kevlar),foams (cups, coolers),glasses,circuit boards/silicon based materials,noble gases and more.
The rock fragments that accumulate at the base if a steep slope are usually known as scree or talus.
Paper decomposes because it is made of organic material. Paper is made of wood and water, so it decomposes rather quickly.
Newspaper. Its not plastic because plastic is not biodegradable.
A degradable pollutant is a pollutant which can be broken down by microorganisms and causes soil pollution. A non-degradable pollutant can not be decomposed or would take an extremely long time to be broken down.
Worms, moss, bacteria, fungi, protists, etc. decompose bio-degradable waste to keep our planet from being knee-deep in garbage.
Definitely. They may dry out and look as they will last forever, but if conditions are right they will decompose like all organic material
Simple Biodegradable waste:- The waste which gets compose quickly through the natural process like the dead remains of the plants and animals, faecal matters, etc.... Complex Biodegradable waste:- Some waste material does not decompose easily and has resistance to breakdown. Such material remains in environment for a long time and as such may prove harmful.
Pollutant
YES Silk is a biodegradable material as it mixes with soil easily
It depends on the material. For example, tin cans take 100 years to decompose, styrofoam cups take 400-500 years and plastics take thousands of years to decompose. Plastics are the materials that has the longest decomposition period because they contain materials that do not decompose easily.
Marine Pollutant
No a virus can not decompose any material including organic.
