What else can I help you with?
Are river rocks porous?
No. It is a fine grained extrusive volcanic rock that is light in color. It is usually not porous.
Which rodents live in the porous volcanic rocks?
Rock hyraxes, also known as rock dassies, are small mammals that live in the nooks and crannies of porous volcanic rocks in Africa. They are herbivorous and have adapted well to living in such environments, utilizing the rocks for shelter and protection.
What are Frothy volcanic rock are called?
Frothy volcanic rocks are called pumice. Pumice forms when lava with high gas content erupts from a volcano and cools rapidly, trapping gas bubbles within the rock, giving it a lightweight and porous appearance.
What is a porours rock?
A porous rock is a type of rock that contains numerous small holes or voids, allowing it to absorb fluids or gases. This porosity is often a result of the rock's formation processes, such as volcanic activity or sedimentation. Common examples of porous rocks include sandstone, limestone, and pumice. The ability to hold water or other substances makes porous rocks significant in fields like geology, hydrology, and environmental science.
Which is the gas and solid in pumicestone?
Solid: volcanic rocks of very different compositions Gas: air and volcanic gases

What rocks are porous?
These are some porous rocks: chalk, limestone, sandstone, pumice, scoria.

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.
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.
Pumice obsidian and scoria are kinds of?
volcanic rocks formed from different processes. Pumice is a light and porous rock formed from foamy lava, obsidian is a dark volcanic glass formed from quickly cooled lava, and scoria is a dark, vesicular rock formed from gas-rich lava.
What makes some rocks porous?
The sediments (grain) have some definite shape and volume. Considering a spherical sediment the packing of the sediments around a grain can be octahedral leaving spaces in between. These are the pore spaces which makes the rocks porous.
What are Frothy volcanic rock are called?
Frothy volcanic rocks are called pumice. Pumice forms when lava with high gas content erupts from a volcano and cools rapidly, trapping gas bubbles within the rock, giving it a lightweight and porous appearance.

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 pumice foliated?
No, pumice is not foliated. Foliation is a term used to describe the layered structure found in certain rocks like schist and slate, whereas pumice is a type of volcanic rock known for its porous and frothy texture formed from volcanic glass and trapped gas bubbles.
What are the rocks that have pores?
Porous rocks.
