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.
Does metamorphic rocks have a higher porosity than sedimentary rocks?
Metamorphic rocks would have less porosity than sedimentary rocks.
Are volcanic rocks porous?
Igneous rocks range from the highly porous pumice to the nearly non-porous granite. In some explosive eruptions of felsic magma, as is the case with pumice, the frothy mixture of rock and gas cools so rapidly that open vesicles are preserved, making it very lightweight and porous. With granite, the intrusive igneous rock has had a long time to cool underground, and with its interlocking crystalline structure, it has an extremely low porosity.
Is metamorphic rock non porous rock?
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.
How do fine grain igneous rock form?
Fine-grained igneous rocks form when the magma cools quickly.
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 are the three types of rock and their formation?
there are 4 bill bob and jerry and the one in abi's head she likes to call a brain Igneous, Sedimentary, and Metamorphic.
Can metamorphic rocks float?
The extrusive volcanic rock pumice can float on water. Other extrusive volcanic rocks are not so lucky.
Light-colored igneous rocks are less what than dark-colored igneous rocks are?
less dense
Does the grand canyon have a rock called metamorphic?
Yes. There are some metamorphic rocks in the Grand Canyon.(there are much more sedimentary and even some -though less- igneous rocks too!)
Are black diamonds more or less expensive than regular diamonds?
Black diamonds are more porous and from younger sedimentary rocks, so they are not as expensive as other diamonds.
Does metamorphic rocks have a higher porosity than sedimentary rocks?
Metamorphic rocks would have less porosity than sedimentary rocks.
Light colored igneous rocks are less what than dark igneous rocks?
basaltic rocks are darker because they are more dence granitic rocks are less dence so they are lighter
Is sandstone extrusive?
sedimentary rock are extrusive when the were formed outside land than in the dirt extrusive rocks take less time to form than intusive (formed under ground) becase wind and help it form faster. i hope this is very helpful =)
Are rocks that are changed by metamorphism more porous or less?
Than?? Marble certainly isn't porous.
How does the density of a light colored igneous rock differ from that of a dark colored igneous rock?
Normally, light colored igneous rocks are less dense compared to dark colored igneous rocks. This is because the light colored rocks have a less iron in them.
What are the main things about sedimentary rock?
Usually, sometimes sedimentary rocks can be found creating on the side of pool's. And even though sedimentary rock is small, they can be used for big thing. Like houses, or even sculptures. 6 billion years ago when the earth was forming there were no Sedimentary rocks, as well as metamorphic, but there were igneous rocks. It was 3.9 billion years ago when the first sedimentary rocks began to appear!
