on a molecular level they are different.
the polymers they are made up of have different shapes
No, not all plastics are petrochemicals. A few examples of bioplastics (plastics made from biologic sources) include Polyhydroxyalkanoates, Polylactic Acids and a wider variety of starch based plastics.
Glass, some plastics, air, water, and others.
Thermosetting plastics such as polyoxybenzylmethylenglycolanhydride better know as 'Bakelite' and some others.
There are two types of plastic: thermosetting and thermoplastic.Thermosetting plastics, such as Bakelite, use resins that are baked into their final form, usually in a mould. The chemical reaction of baking changes the resin so that it can no longer become fluid if reheated. These plastics cannot be "remolded", only powdered and put to other uses.Thermoplatics (the bulk of plastic materials) use resins that are not baked in their moulds. Thermoplastics are heated until they flow, then cast into shape. Because they are only heated to flow temperature, no chemical reaction of heating occurs, and they can be re-moulded in a recycling process.p.s. Bakelite is named for its inventor, Baekland, not because of its processing. True Bakelite is dark brown to black, so light-coloured "hard plastic" radio cabinets are *not* Bakelite - they are commonly Catalin, urea formaldehyde, or some other resin.
Some plastics dissolve in acetone, like styrene. Others don't - nail polish remover comes in plastic bottles, so there are plastics that will hold it.
Non-biodegradable materials are those that cant be broken down within a reasonable time span. Some examples include plastics, batteries, glass, computers and cellphones. New research now shows that some plastics do break down.

Some are made of standard plastics, while others are bio-degradable.
it depends on the park. some parks you can, others, you cant
Some of them we could possibly live on and others we cant.
Wise monkeys are ones that can do things others cant. Some of them can do very intelligent actions unlike others.
