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

What happens When the lava stops erupting out of the central vent what is left at the top?

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.


What is the name of volcanic rock with air bubbles found at Mount Vesuvius?

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.


What is a event when a volcano enjects gas liquid and solid materials into the atmosphere and surrounding area?

This is the description of a volcanic eruption.A eruption.


What is the tall column in which water and steam erupting from the earth's surface is called?

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.


What are Frothy volcanic rock are called?

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.


What is the tall column of water and steam erupting from the earths surface called?

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.


Are volcanoes volcanoes before they erupt?

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.


What makes bubbles form into rocks?

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.


What is a open cavity in a volcanic rock that was filled by gas bubble when the lava was still mainly liquid?

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.


What type of rock has holes in it?

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.


Is a volcano called volcano only when it is erupting?

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.
