This is known as pumice.
What is the solid form of lava that is so frothy with gas when it reaches the surface?
Pumice is volcanic rock formed from frothy lava. It will usually float on water because of all the gas bubbles in it.
Which igneous rocks would be formed by the fastest cooling of lava?
Glassy textured extrusive igneous rock, such as obsidian.
What causes the frothy appearance of pumice and scoria?
Both are formed during the eruption of gas-rich lava. The gas forms bubbles in the lava, which remain in place after it solidifies.

Is pumice foliated?
Pumice is a light and porous volcanic rock formed when glassy lava solidifies rapidly. Some pumice clasts are known to be foliated.
What rock is black glassy and was formed by rapidly cooling lava?
The answer is pitchstone. it is and igneous rock.

Why does obsidian have a glassy texture?
Obsidian has a glossy texture is because of how it is formed. When it solidifies, it does not crystallize due to the lava cooling too quickly.
Obsidian is a glassy form of?
Extruded lava.
What is smooth glassy lava called?
Obsidian.
