Today most plastics are made from crude oil and natural gas, although they can be also produced from corn and other biomasses. First, refineries process the crude oil to produce fuels, such as gasoline, and many petrochemicals. Petrochemicals then are used by chemical plants to obtain many products, like fertilizers, lubricants, and plastic resins. Plastic resins are, in turn, used to produce many different types of plastics.
Refineries and manufacturers use process called Catalytic Cracking to break Crude Oil into Liquefied Gases, Gasoline, Diesel, Asphalt, and many others, and then reforming and alkylation processes to turn simple hydrocarbons of Liquefied Gases and/or Naphtha into polymers (chains of molecules). Polymers are then processed into plastics that we know today.
Oil is a carbon-rich raw material, and plastics are large carbon-containing compounds. They're large molecules called polymers, which are composed of repeating units of shorter carbon-containing compounds called monomers.
The process involves both kinds of change. Essentially it's chemical because plastics are different substances from the hydrocarbons in oil. However, some steps such as fractional distillation are physical.
It's made during the refining process of the oil, where petroleum is the base that you use to make plastic.
It's a chemical change. You are transforming one molecule (the hydrocarbons used as base stock) into another (the polymer).
These are chemical changes,
A chemical change involve chemical reactions and the transformation of reactant molecules in products molecules.

Oil.

Plastic is made from oil, so some kinds of vegetable oil are being used to make plastic. This is usually bio-degradable, so it breaks down in landfills and oceans.
A plastic always sink in oil like a plastic bottle will always float in oil.
On a 2005 Forrester you need to take out 8 or 10 plastic screws in the underneath splash shield then you can turn it out of the way giving you excess to oil plug.
Plastic bottles, atlhough originally made from petroleum, do not leach oil; the oil has been transformed into plastic and there is no oil in the plastic. Plastic bottles may, in some cases, leach bisphenol A, which is a plasticising agent (i.e., it is used to make the material more flexible).
Plastic is made from oil which comes from oil fields, on land or at sea
Crude oil is the most common type of oil that is found in plastic. Oil is considered to be a carbon-rich raw material.
Plastic is made from oil, usually fossil fuel oil.
plastic will float in water because it is lighter than oil

yes
In any country that has oil. Since plastic is made from oil, pretty much any country with oil can make and manufacture oil. Hope I helped. =)
