You can determine if a rock is porous by observing if it has small holes or open spaces on its surface. Porous rocks will also generally have a high water absorption rate when placed in water, causing them to become heavier. Conducting a porosity test, such as measuring the volume of water absorbed by the rock, can also help determine its porosity.
Granite: A durable and dense rock that is resistant to water absorption due to its low porosity. Basalt: A fine-grained volcanic rock with low porosity that is commonly used in construction and landscaping. Marble: A metamorphic rock that is often polished and used in countertops and sculptures due to its non-porous nature.
Porous volcanic rock is commonly classified as either pumice or scoria. Pumice is often lighter in color and has a very porous texture due to the presence of numerous gas bubbles, while scoria is darker and similarly porous but is typically more dense than pumice. Both are formed from volcanic eruptions and can float on water.
porous rocks are rocks through which water etc. can seep or pass through.
No. It is a fine grained extrusive volcanic rock that is light in color. It is usually not porous.
Pumice is a light, porous volcanic rock that is commonly used in beauty and skincare products for exfoliation. It forms when volcanic lava rapidly cools and traps gases, creating its characteristic porous texture.

Yes. Chalk is a porous rock.
The story proved to be quite porous. Lava is a porous rock.

No, gabbro is not a porous rock. Gabbro is a dense, coarse-grained igneous rock that is formed from the slow cooling of magma beneath the Earth's surface. It typically does not have significant porosity or permeability.

Non-porous rocks are solid materials that do not allow water or other fluids to pass through them due to the absence of interconnected pore spaces. This lack of porosity prevents the storage or movement of fluids within the rock, making them impermeable. Examples of non-porous rocks include granite, basalt, and marble.
Space between the particles of the rock.
Granite is considered a low-porosity rock, meaning it has very small, interconnected pores. While it is not as porous as some other types of rock, like sandstone, granite can still absorb water and other liquids if not properly sealed.
The rock is porous.

Yes. Since metamorphic rocks are rocks that have been changed through intense heat and pressure, they have been compacted and are more dense. For example, a conglomerate is a sedimentary rock comprised of large grains of gravel that have been cemented together, and can be porous. When a conglomerate undergoes massive heat and pressure, it is metamorphosed into a metaconglomerate, which is more dense and not at all porous.
