they are often porous because of fossil imprints and pressure put on them at different spots

Are igneous rocks less porous than sedimentary rocks?
Sedimentary rocks tend to be more porous than igneous rocks because there is more open space between the individual sediment grains than between the minerals in a crystallized rock.
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 rocks are porous?
These are some porous rocks: chalk, limestone, sandstone, pumice, scoria.
What rocks are formed when sediments are compressed compacted and cemented togerther?
Sedimentary rocks.
What rocks are formed from broken rocks?
Clastic sedimentary rocks and Cataclasites (a form of metamorphic rock) are formed from broken rocks.
What types of materials are Porous?
Sedimentary rocks such as sandstone are examples of porous materials.
Are igneous rocks less porous than sedimentary rocks?
Sedimentary rocks tend to be more porous than igneous rocks because there is more open space between the individual sediment grains than between the minerals in a crystallized rock.
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.

Rocks formed from weathered debris from preexisisting rocks are called?
They are called clastic sedimentary rocks.
Are sedimentary rocks classified tofoliated sedimentary rocks?
Metamorphic rocks are classified by foliation or lack there of, not sedimentary rocks. They are classified into Clastic Sedimentary, and Chemical Sedimentary.
What are 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.

Are sedimentary rocks formed from fragments of other rocks chemical sedimentary rocks?
No. The rocks you describe are clastic or detrital sedimentary rocks.
What has the author Sam Boggs written?
Sam Boggs has written: 'Petrology of sedimentary rocks' -- subject(s): Sedimentary Rocks 'Petrology of sedimentary rocks' -- subject(s): Rocks, Sedimentary, Sedimentary Rocks
Are there any fossils in sedimentary rocks?
Yes all fossils occur in sedimentary rocks or rocks that began as sedimentary rocks.
What are the rocks that have pores?
Porous rocks.
