they are often porous because of fossil imprints and pressure put on them at different spots
What else can I help you with?
Are igneous rocks less porous than sedimentary rocks?
Generally, yes. Igneous rocks are typically less porous than sedimentary rocks because they form from molten magma that cools and solidifies quickly, leaving minimal space for pores to form. Sedimentary rocks, on the other hand, are often composed of loose grains or fragments that can create more pore spaces within the rock.
Which types of rocks contains coal and petroleum?
Coal is typically found in sedimentary rocks such as sandstone, shale, and limestone. Petroleum is found in sedimentary rocks as well, usually in porous reservoir rocks such as sandstone or limestone that are capped by impermeable rock layers like shale or mudstone.
What types of rocks contain oil?
Sedimentary rocks, such as sandstone and limestone, are commonly associated with oil deposits. When organic matter accumulates and gets buried over time, it can transform into oil and become trapped in porous rock formations. These sedimentary rocks serve as reservoirs for oil extraction.
Why are sedimentary rocks softer than igneous rock?
It's because sedimentary rocks have big air spaces in them which makes them very porous, whereas igneous and metamorphic rocks are less porous, as the crystals are tightly packed.
What kinds of sedimentary rocks are oil and natural gas found?
Oil and natural gas are typically found in sedimentary rocks such as sandstone, limestone, and shale, where they accumulate in porous spaces or traps created by layers of impermeable rock above and below. The sedimentary environment plays a key role in the formation and trapping of these hydrocarbons.

Is porous a rock formed from grains stuck together?
A rock formed from grains stuck together would be Porous
How can one visually identify rocks as sedimentary rocks?
Research has shown that it is not always very easy to identify sedimentary rocks with the naked eye. It has been stated that sedimentary rocks are porous and may contain small holes. Also, if one is to rub the rock and small grains tend to come off it might also be sedimentary.
Are sedimetary rocks vesicular?
No, sedimentary rocks are generally not vesicular. Vesicular rocks are typically igneous rocks that contain gas bubbles trapped during cooling, creating a porous appearance. Sedimentary rocks form from the accumulation and compression of sediments, which do not typically contain vesicles.
Rocks formed from weathered debris from preexisisting rocks are called?
They are called clastic sedimentary rocks.

What types of materials are Porous?
Sedimentary rocks such as sandstone are examples of porous materials.
What are the properties of sedimentary rock?
sedimentary rocks have layers showing the deposition of sediment at different time periods.sedimentary rocks consists of lots of small grains. these grains maybe weakly and together so the rocks are often porous and maybe soft and crumbly.sedimentary rocks often have fossils trapped with in them.sedimentary rocks consist of layers of lots of small particals.
