The mixture of crude oil and petroleum that comes straight from the ground is called crude oil.

Here's why:

* Crude oil is the unrefined form of petroleum.

* Petroleum is a broad term referring to a naturally occurring mixture of hydrocarbons found in the Earth's crust.

* Crude oil is the raw material from which many different products are made, including gasoline, diesel fuel, kerosene, and plastics.

So, while "petroleum" is a more general term, "crude oil" specifically refers to the mixture of hydrocarbons extracted from the ground before any refining processes.
