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.
vesicular
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.
Scoria and pumice are vesicular igneous rocks.
The answer is Shale. Slate is a metamorphic rock derived from shale, granite is an intrusive igneous rock, and pumice is a vesicular extrusive igneous rock.
Vesicular basalt has small rounded voids called vesicules formed by the molten rock cooling and freezing around pockets of gas. It looks a lot like a rock hard sponge. Non vesicular basalt is a normal solid rock.

A rock with little to no grain development and a vesicular texture is typically called a vesicular rock. It is formed from a volcanic eruption, where gases trapped in the lava create bubbles or vesicles. The most common example is vesicular basalt.
Yes. Pumice is so fine-grained, often times it's crystals are vesicular and glassy.
No. Pumice is a glassy vesicular volcanic rock.
No. Pumice is a glassy vesicular volcanic rock.
vesicular
Pumice
yes a porous vesicular rock or stone
I may be wrong, but it might be volcanic rock.
Scoria is a highly vesicular (porous), dark colored volcanic rock.
It has a vesicular texture.
