It is made up of porous materials.
The correct answer is: It traps the deposits inside them.
To arrive at this answer, we need to understand the characteristics of impermeable rocks and how they relate to oil and natural gas deposits.
Impermeable rocks are rocks that do not allow fluids or gases to pass through them easily. They act as a barrier, preventing the flow of substances. In the context of oil and natural gas deposits, impermeable rocks are crucial because they keep the hydrocarbons trapped within them.
Oil and natural gas are typically formed deep underground over millions of years. These hydrocarbons accumulate in porous rocks that have spaces or pores within them. However, these porous rocks alone cannot hold the oil and gas in place. This is where impermeable rocks come into play.
Impermeable rocks, also known as seals or cap rocks, have very low permeability, meaning they do not allow the hydrocarbons to escape easily. As oil and gas migrate through the underground layers, they reach a point where they encounter an impermeable rock layer. This rock layer acts as a confining layer, trapping the oil and gas beneath it.
Therefore, when we say that an impermeable rock is where oil and natural gas deposits are found, we mean that these rocks function as a reservoir, keeping the precious hydrocarbons locked in place.
