When a volcano erupts explosively, some of the molten rock is ejected in the form of small particles. These cool to form tiny pieces of volcanic glass. Clouds of volcanic ash either race down the sides of a volcano in avalanches called pyroclastic flows, or fall to earth like snow from tall eruption plumes. In either form volcanic ash can be dangerous. Pyroclastic flows are extremely hot, burning almost everithing in their paths. Falling ash has had time to cool, but still prsents hazards. It is very dense and can cause roofs to collapse. It clogs engines and interferes with electical equipment. It can damage the lungs if inhaled. Volcanic ash can also mix with water from rain or melting glaciers to form deadly mudflows called lahars.

What is bedrock in a volcano?
Bedrock in a volcano refers to the solid, unweathered rock that lies beneath the volcanic materials such as ash, lava, and pyroclastic flow deposits. It forms the foundation on which the volcano is built and can help determine the stability and structure of the volcano.
What is an ash cloud from a volcano?
An ash cloud is something which comes out of the volcano
Is an ash fall a volcano?
No, an ash fall is not a volcano. An ash fall occurs when volcanic ash and debris are ejected from a volcano during an eruption and then carried by winds to surrounding areas, causing the ash to fall to the ground.
What is the name of the volcano that has caused the ash cloud?
The volcano that has caused the ash cloud is called Taal Volcano, located in the Philippines.
A volcano that is fairly symmetrical and has both layers of lava and pyroclastic deposits is a what?
A volcano that is fairly symmetrical and has both layers of lava and pyroclastic deposits is a stratovolcano, also known as a composite volcano. These volcanoes are characterized by their steep-sided conical shape and alternating layers of lava flows, volcanic ash, and pyroclastic debris. They are capable of explosive eruptions due to their viscous magma composition.

What is inside of a volcano and outside of a volcano?
Inside a volcano, there is magma (molten rock), gases, and sometimes solid rock fragments. Outside a volcano, you'll find the volcano's cone, made of layers of ash, lava, and other volcanic materials. The surrounding area might also have lava flows, ash deposits, and volcanic gases.
What is supervolcanoes?
A Supervolcano is a volcano characterized by the large area it affects. A supervolcano is generally accepted to be a volcano that discharges ash, lava, or pumis deposits that spread over 240 or more cubic miles from its center. The Indonesian Toba is an example of a supervolcano.
What is the definition of mound in a volcano?
A mound in a volcano is a raised area or hill that forms on the volcano's surface due to accumulated deposits of volcanic material, such as lava, ash, and rocks. These mounds can vary in size and shape, and are commonly found on the summits or flanks of volcanoes.
Which volcano hazard can be dangerous to passing sir planes due to its fine, abrasive quality?
Volcano ash hazard can be dangerous.
What is volcano rock?
A volcano rock is rock formed from ash or lava erupted from a volcano.
Can ash from a volcano break glass?
If the amount of ash is great enough.
What type of volcano is MtRuapehu?
It is an active volcano and spills out ash and lava.
