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.
What else can I help you with?
One kind of volcanic glass that has holes caused by pockets of gas?
Pumice is a type of volcanic glass that contains holes caused by pockets of gas trapped during its formation. These holes give pumice a lightweight and porous texture, making it commonly used in beauty products and as an abrasive.
Will scoria float or sink in water?
Scoria is a type of volcanic rock that is typically denser than water, so it will sink in water.
Is scoria formed above ground?
Yes. Scoria is formed in lava fountains that occur during some volcanic eruptions.
What is the environment of scoria?
Scoria is typically found in volcanic environments, such as volcanic craters or areas where volcanic eruptions have occurred. It forms when lava cools rapidly and traps gases inside, creating a porous structure with a dark, reddish-brown color.
Is scoria permeable?
Scoria is a type of volcanic rock that is generally porous and can be permeable depending on its porosity. The vesicles (holes) in scoria contribute to its permeability, allowing fluids to pass through it.
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 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.
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 minerals present in scoria?
Scoria typically contains minerals such as plagioclase, pyroxene, olivine, and magnetite. These minerals are commonly found in volcanic rocks and contribute to the characteristic appearance and composition of scoria.
Is scoria metamorphic?
no, extrusive because it is made by lava not magma.
Is granite the lightest rock?
no scoria is the lightest it is volcanic and has many holes in
