Which describes an impermeable rock where oil and natural gas deposits are found?
OIt has pores large enough to allow absorption.
O It only allows certain materials to pass through.
OIt is made up of porous materials.
OIt traps the deposits inside them.
The correct answer is: O It traps the deposits inside them.
To understand why an impermeable rock is where oil and natural gas deposits are found, we need to first understand the concept of permeability. Permeability is the ability of a substance to allow fluids to pass through it. In the case of rocks, permeability refers to the ability of a rock to allow the flow of fluids, such as oil and gas, through its pores.
An impermeable rock, on the other hand, has a very low permeability, which means it does not allow fluids to pass through easily. This characteristic makes it ideal for the accumulation and retention of oil and natural gas deposits.
When oil and natural gas are formed deep beneath the Earth's surface, they typically migrate through the rock layers until they are trapped by impermeable rocks. These rocks act as barriers, preventing the upward flow and escape of the hydrocarbons. Over time, more oil and gas can accumulate in the reservoir created by the impermeable rock, leading to the formation of valuable oil and gas deposits that can be extracted.
In summary, an impermeable rock is where oil and gas deposits are found because it acts as a barrier, trapping and containing the hydrocarbons within its layers.
