There are several different rocks that are formed in this manner, depending upon the makeup of the lava. You are probably looking for one of these three answers:
pumice
scoria
vesicular basalt
The volcanic rock with air bubbles found at Mount Vesuvius is called pumice. Pumice forms when volcanic gases are rapidly released from magma during an eruption, creating a frothy texture with numerous air pockets.
This is the description of a volcanic eruption.A eruption.
Frothy volcanic rocks are called pumice. Pumice forms when lava with high gas content erupts from a volcano and cools rapidly, trapping gas bubbles within the rock, giving it a lightweight and porous appearance.
The open cavity is called a vesicle, and it forms when gas bubbles are trapped in the lava as it solidifies. These gas bubbles can result from dissolved gases being released as pressure decreases during volcanic eruptions. Over time, minerals or other materials can fill the vesicles, creating unique features in the volcanic rock.
A volcano is called a volcano whether it is erupting or not.It is called an active volcano if it is erupting or has erupted recently.It is a dormant volcano if it hasn't erupted in a long time.Extinct volcanoes are not expected to ever erupt again.
When lava stops erupting out of the central vent, it solidifies and forms a volcanic rock structure called a volcanic plug or volcanic dome at the top of the vent. These structures can vary in size and shape depending on the type of lava that was erupted and the eruption style.

The tall column in which water and steam erupting from the earth's surface is called a geyser. Geysers are natural phenomena typically found in areas with volcanic activity, where underground water comes in contact with hot rocks and rises to the surface in a dramatic display.
Frothy volcanic rocks are called pumice. Pumice forms when lava with high gas content erupts from a volcano and cools rapidly, trapping gas bubbles within the rock, giving it a lightweight and porous appearance.
That is called a geyser, which is a natural hot spring that periodically erupts jets of water and steam into the air due to underground volcanic activity.
Yes they are. A volcano that is not erupting is called a dormant (meaning sleeping) volcano, while one that is erupting is called an active volcano.
Bubbles in rock form when gas-rich magma cools and solidifies without the gas being able to escape. The trapped gas forms bubbles within the cooling rock, creating a porous texture. Over time, the solidified rock with bubbles can become a type of volcanic rock called vesicular basalt.
The open cavity is called a vesicle, and it forms when gas bubbles are trapped in the lava as it solidifies. These gas bubbles can result from dissolved gases being released as pressure decreases during volcanic eruptions. Over time, minerals or other materials can fill the vesicles, creating unique features in the volcanic rock.
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.
