Define the term source rock.

A source rock is a type of sedimentary rock that contains organic matter (such as dead plants and animals) that can generate hydrocarbons (such as oil and gas) when subjected to heat and pressure over millions of years. Source rocks are the starting point for the formation of oil and gas deposits, as the organic matter within them breaks down and transforms into hydrocarbons through a process known as maturation.

A source rock is a sedimentary rock that contains organic matter that can be converted into petroleum or natural gas.
