Tephra flow is fragments of volcanic rock and lava. Pyroclastic flow is fast moving current of hot gas and rock.
What else can I help you with?
What is Pieces of rock and debris that are carried within lava and propelled through the air during an eruption are called?
Volcanic airborne debris is classified as either solid (tephra, aka pyroclasts, including "volcanic bombs") or particulate (ash). Lava chunks ejected into the air around a vent is called "spatter."*When solids condense from gaseous pyroclastic flows, the rock material is called ignimbrite.
Are pyroclasts formed by basaltic magma or andesitic magma?
Pyroclasts can be formed by both basaltic and andesitic magma. Basaltic magma typically forms pyroclastic materials like scoria and ash, while andesitic magma can produce a variety of pyroclasts including volcanic bombs and pumice. The type of pyroclasts produced depends on factors such as the composition of the magma and the eruption style.
The particles produced in volcanic eruptions are called what?
The pulverized particulates are called ash. Larger chunks of magma are called tephra.
What is the name of the largest sized tephra?
Blocks is the name used for the biggest pieces of tephra. Tephra is produced by a volcanic eruption.
What is a medium sized tephra called?
A medium-sized tephra fragment is typically called lapilli. These fragments are between 2 and 64 mm in size and are formed during explosive volcanic eruptions.

What are pyroclastics?
Pyroclasts are rock fragments or rocks formed from volcanic fragments thrown into the air as a result of a volcanic eruption. Also known as tephra, some examples of these rocks include pumice, reticulite and scoria.
The particles produced in volcanic eruptions are called what?
The pulverized particulates are called ash. Larger chunks of magma are called tephra.
What type of eruption is characterized by abundant pyroclasts?
The type of eruption that is characterized by an abundant pyroclasts is Strombolian eruption. Large blobs of lava and hot rock, called pyroclasts, are tossed from its central vent during this eruption.
What is the name of the largest sized tephra?
Blocks is the name used for the biggest pieces of tephra. Tephra is produced by a volcanic eruption.
What is a medium sized tephra called?
A medium-sized tephra fragment is typically called lapilli. These fragments are between 2 and 64 mm in size and are formed during explosive volcanic eruptions.
What is bits of rock or solidified lava dropped from the air after a volcanic eruption?
tephra, or debris from the eruption of a volcano:)
What volano is made entirely of tephra?
A tephra cone volcano, also known as a cinder cone volcano, is made entirely of tephra. Tephra is a term for fragmented material produced by a volcanic eruption, such as ash, cinders, and bombs. Tephra cone volcanoes are typically small in size and have steep slopes due to the build-up of tephra fragments from explosive eruptions.
Large round or streamlined tephra are called?
Large round tephra are called bombs, while streamlined tephra are known as lapilli.
What are the three types of volcanoes and what are the difference?
cinder strato and shield shield is the least dangerous and the lava slowly flowsa down cinder erupts tephra not lava like a shield and is cone shaped strato is the most dangerous it erupts both tephra and lava
What is the difference between tephra and pyroclastic flow?
Tephra refers to fragmented volcanic material ejected during an eruption, including ash, lapilli, and bombs. Pyroclastic flow is a fast-moving mixture of hot gas and volcanic particles that flows down the side of a volcano during an explosive eruption, capable of reaching speeds of hundreds of kilometers per hour and causing widespread destruction.
