The definition of pervious in regards to rocks is (of a substance) allowing water to pass through; permeable: pervious rocks.
Pervious rocks are rocks that allow water to pass through them easily due to their high porosity and permeability. This property makes them important in groundwater storage and movement, as they can act as natural aquifers or conduits for water flow. Examples of pervious rocks include sandstone, limestone, and conglomerate.
Pervious rock is a type of rock, like limestone, which allows water to flow through it
Pervious surfaces are materials or surfaces that allow water to pass through them, such as grass, gravel, or permeable concrete. This helps to reduce stormwater runoff and allows rainwater to be absorbed into the ground, replenishing groundwater supplies.
Some rocks that are known to absorb water include sandstone, limestone, and shale. These rocks have interconnected pore spaces that allow water to be drawn in and stored within their structure.
Rocks just off the coast of an island are typically called sea stacks or offshore rocks. These formations are created through erosion and can vary in size and shape, adding to the natural beauty of the coastline.
Plants benefit from rocks and boulders in their environment as they provide stability for roots, help with water retention, and prevent erosion. In addition, rocks can serve as an anchor for plants to grow and provide a habitat for beneficial insects and microorganisms.

Underground water that is held in the soil and in pervious rocks.
Pervious surfaces are materials or surfaces that allow water to pass through them, such as grass, gravel, or permeable concrete. This helps to reduce stormwater runoff and allows rainwater to be absorbed into the ground, replenishing groundwater supplies.
An impervious rock is one that does not allow water to flow through it. It has no air spaces and has no way of storing water at all.
Lime stone is a porous rock as it absorbs water.
Spring water is water that is held underground in the soil and in pervious rocks. It is said to be healthier because of less contamination.

When water is able to enter rocks, it is because they are permeable. Permeable rocks either have spaces (pores - porous rocks, e.g. sandstone), or paths through their structure (pervious rocks, e.g. limestone). These features can only be found in sedimentary/clastic rocks. Clastic means that it is made up of small particles cemented together, which gives it a grainy texture. Metamorphic and igneous rocks are crystalline, which mades them impermeable because the crystals interlock, blocking a flow of water.
These are rocks that are highly compacted, having little or no pore spaces within their grains. They do not readily allow the passage of water through them.
