What is the difference between a vesicular igneous rock and a nonvesicular igneous rock?

Vesicular rocks contain lots of small cavities, usually filled with air. Non- vesicular ones don't have these holes. Vesicles are formed when magma suddenly rushes out on to the surface and its dissolved gases come out of solution, blowing bubbles in the liquid rock which are preserved as it cools quickly and sets. An example of a vesicular rock is pumice.

What are four felsic igneous rocks?
vesicular rhyolite, rhyolite, granite, and pegmatite!
Lava rock with air pockets?
Scoria and pumice are vesicular igneous rocks.
What are vesicles in an igneous rock?
Vesicles are rounded spaces that appear in igneous rocks from the solidification of the magma around gas bubbles. Pumice, scoria, and vesicular basalt are igneous rocks that contain vesicles.
Igneous feature would you find rocks with a vesicular texture?
Vesicular igneous rocks cool quickly from magma, resulting in pockets of trapped gas or gas bubble imprints that make it appear porous. Pumice and scoria are examples of igneous rock with vesicles.
How is the vesicular texture of an igneous rock formed?
A vesicular texture is one where there are small voids within the igneous rock. These tend to form in extrusive igneous rocks due to the loss of confining pressure which causes gasses dissolved in the molten material to come out of solution or exsolve. These gasses form bubbles within the cooling lava and can become trapped if the lava cools rapidly, leaving a permanent gas bubble or void space within the solidified igneous rock.
What are examples of igneous rock?
nothing
An igneous rock with lots of gas bubble voids has a?
It has a vesicular texture.
Lava rock with air pockets?
Scoria and pumice are vesicular igneous rocks.
What are four felsic igneous rocks?
vesicular rhyolite, rhyolite, granite, and pegmatite!
Which are igneous rocks?
== == Igneous rocks have formed from molten material either above (extrusive) or below (intrusive) ground level. Extrusive igneous rocks include obsidian, basalt, and rhyolite; intrusive igneous rocks include gabbro and granite.
What is the difference between basaltic and frantic igneous rock?
There sedimentary igneous and metemorphic
What is vesicular texture in rock?
* Vesicular rock texture is generally displayed in extrusive igneous rocks which contain many vesicles of trapped air, such as pumice or scoria. * Igneous rocks containing holes which were produced as gases escaped from the upper part of lava flow.
Where does pumice form?
Vesicular solidified lava, an extrusive igneous rock.
What are vesicles in an igneous rock?
Vesicles are rounded spaces that appear in igneous rocks from the solidification of the magma around gas bubbles. Pumice, scoria, and vesicular basalt are igneous rocks that contain vesicles.
In what type of igneous rock most of the time ore minerals are found?
Vesicular basalt or pegmatite veins.
What is the rock that is full of tiny connected air spaces?
You are probably thinking of pumice, and igneous rock.
How is pumice classified?
Pumice is classified as a felsic, glassy, highly vesicular, extrusive igneous rock.
