porous rock

Porous rock is a type of earth material that contains tiny holes or spaces called pores. These pores can store fluids like water, oil, or gas, allowing the rock to act as a natural reservoir. The size and connectedness of the pores determine how much fluid the rock can hold and how easily the fluid can flow through it. Examples include sandstone and limestone. Porous rocks are important in natural processes such as groundwater movement, petroleum storage, and geothermal energy. Understanding their properties helps in resource extraction and managing water supplies effectively.
