"Petroleum" products are distilled from crude oil, so what comes out of the ground is crude oil.

As it comes from one source, and contains not other ingredients, it is homogenous. To be a 'mixture' it would need to have something added.
Petroleum occurs in porous and permeable rock which is surrounded by less porous and impermeable rock which prevents or slows its eventual escape to a body of water or the surface.
gas and other stuff are all made out of the stuff that comes out of the ground called petroleum.
Crude oil straight out of the ground is not uniform (clean), but is composed of many fractions which can be extracted simply by weight. Other fractions can be 'cracked' by heat, pressure, solvents and distillation. To distinguish from other, purer oils, the basic material is called 'crude'. Strictly speaking, 'petroleum' itself is a fraction of crude.
Petroleum is recovered from the ground by drilling deeply into the ground. There are also many other Fossil Fuels, if you would like to look them up. They are all taken from the ground.
Petroleum safety is the absence of injury or illness when using or exposed to petroleum or during its extraction from the ground.

Together with natural gas, it makes up petroleum, which is Latin for "rock oil". Petroleum is basically a mix of naturally occurring organic compounds from within the earth that contain primarily hydrogen, carbon and oxygen. When petroleum comes straight out of the ground as a liquid it is called crude oil if dark and viscous, and condensate if clear and volatile. When solid it is asphalt, and when semi-solid it is tar. There is also natural gas, which can be associated with oil
Petroleum and coal.
they both are made from the ground
petroleum is usually taken form the ground by drilling a narrow hole into a petroleum deposit and simply pumping out the oil
