Which describes an impermeable rock where oil and natural gas deposits are found it has pores large enough to allow absorption it is made up of porous materials it only allows certain materials to pass through it traps the deposits inside them
- It only allows certain materials to pass through it.
The description that matches an impermeable rock where oil and natural gas deposits are found is: it only allows certain materials to pass through it and traps the deposits inside them.
The description you provided does not match that of an impermeable rock. Impermeable rocks are dense and do not allow the flow or transmission of fluids, including oil and natural gas. Instead, the description you provided matches that of a permeable rock.
Permeable rocks have interconnected pore spaces that allow fluids like oil and natural gas to flow through them. These rocks are typically composed of porous materials, such as sandstone or limestone, which have larger pore spaces that enable the absorption and storage of oil and natural gas. As a result, permeable rocks act as reservoirs, trapping and containing oil and gas deposits within their pore spaces.
In contrast, impermeable rocks, such as shale or clay, have tightly packed and less interconnected pore spaces. They do not allow the movement of fluids and thus act as barriers, preventing the escape or flow of oil and gas deposits. Impermeable rocks are important in the petroleum industry as they can form "cap" or "seal" rocks, preventing the upward migration of oil and gas and allowing them to accumulate in porous, permeable rocks below.
