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.

What rocks are porous?
These are some porous rocks: chalk, limestone, sandstone, pumice, scoria.
Definition of a porous rock?
Porous rocks are like sandy soil and water seeps through these rocks.
What type of rock has holes in it?
Volcanic rocks with gas bubbles are called vesicular. This, however, is a descriptive term rather than an actual rock types. Some vesicular volcanic rocks include pumice, scoria, and vesicular basalt.
When rocks undergo weathering they become?
porous
Is bathstone porous?
By bathstone I assume you mean Pumice which is a volcanic rock with bubbles of gas trapped inside. And yes, it is usually porous
Which rodents live in the porous volcanic rocks?
Chincillas
What makes volcanic rocks light and porous?
please help me computer
Are river rocks porous?
No. It is a fine grained extrusive volcanic rock that is light in color. It is usually not porous.
What type of rock is porous volcanic rock?
Common, hihgly porous types of volcanic rock are pumice and scoria.
Is obsidian porous?
Obsidin rock, or volcanic glass is non-porous.
What are the rocks that have pores?
Porous rocks.
What rocks are porous?
These are some porous rocks: chalk, limestone, sandstone, pumice, scoria.
Is onyx non porous?
Obsidian, volcanic glass, is quite non-porous.
Can metamorphic rocks float?
The extrusive volcanic rock pumice can float on water. Other extrusive volcanic rocks are not so lucky.
How can there be a rock that floats and what are three ways that this rock can be formed?
Very porous rocks such as pumice can be very light and have the potential to float on water. Pumice is a volcanic rock.
Definition of a porous rock?

What does a porous rock mean?
porous rocks are rocks through which water etc. can seep or pass through.
