Yes.
Scoria ("lava rock") is found on the surface of lava flows or in fragments that have ejected from the volcano's explosive opening. In these conditions, the molten rock was immediately exposed to the open air on the Earth's surface, causing it to cool and solidify very rapidly. This solidification process is too quick for atoms within the solution to bind together to form large crystals, so the solid rock is consequently made up of tiny glassy fragments that are amorphous, or do not contain crystalline structures. Since scoria is made up of these glass fragments, it is defined as VOLCANIC GLASS.

One kind of volcanic glass that has holes caused by pockets of gas?
Scoria is the best answer, but under some circumstances, probably pumice
Is scoria formed above ground?
Yes. Scoria is formed in lava fountains that occur during some volcanic eruptions.
What type of rock is porous volcanic rock?
Common, hihgly porous types of volcanic rock are pumice and scoria.
What is the environment of scoria?
Scoria refers to a cindery, vesicular basaltic lava that is a dark colored volcanic rock. Its environment is typically near volcanoes.
What rock has air bubbles in it?
I may be wrong, but it might be volcanic rock.
Is volcanic glass full of air spaces?
Not necessarily. Scoria and pumice are forms of volcanic glass that contain air spaces, while obsidian, another volcanic glass, contains minimal air spaces if any.
What is volcanic glass?
Volcanic glass is material produced by a volcano that lacks any sort of crystalline structure. While most rocks contain crystals in some form of another, glass does not. Volcanic glass usually forms when molten rock cools too quickly to form a crystalline structure. Examples of volcanic glass include obsidian, ash, pumice, and scoria.

What are the properties of scoria rock?
Scoria is a highly vesicular (porous), dark colored volcanic rock.
Is scoria formed above ground or underground?
Scoria is formed above ground during volcanic eruptions.
Is scoria formed above ground?
Yes. Scoria is formed in lava fountains that occur during some volcanic eruptions.
Is granite the lightest rock?
no scoria is the lightest it is volcanic and has many holes in
What type of rock is porous volcanic rock?
Common, hihgly porous types of volcanic rock are pumice and scoria.
What is the environment of scoria?
Scoria refers to a cindery, vesicular basaltic lava that is a dark colored volcanic rock. Its environment is typically near volcanoes.
Is scoria a fine grained rock?
Scoria is a volcanic igneous rock that is composed of approximately 50% silica and 10% calcium oxide and lesser contents of potash and soda. Its hardness on the Mohs scale is 5 - 6.
What is black volcanic rock?
A few varieties including basalt, obsidian, and scoria.
If a rock has many small holes what is it?
It is possibly a volcanic rock, for example scoria
