Lapilli--Lapilli is pyroclastics the size of walnuts.
Cinders-- Cinders are a type of pyroclastic material the size of a pea. According to the text, Earth An Introduction to Physical Geology, Cinders come in different forms when "ejected lava blobs are pulverized by the escaping gases".
Blocks-- Blocks are particles larger than Lapilli's and are formed by harden lava.
Bombs-- Bombs too help to produce blocks, but they are ejected as lava. They take on an streamline shape. They usually tend to fall on the slopes of a cone volcano and they can be ejected far from the volcano due to the force of escaping gases
I answered this earlier but this is a better answer ;)
What else can I help you with?
The particles produced in volcanic eruptions are called what?
The pulverized particulates are called ash. Larger chunks of magma are called tephra.
What are burnt particles from a volcano eruption called?
Tephra refers to any airborne particles from a volcanic eruption, and includes pumice, cinders, dust, and ash. Ash refers to particles smaller than 2 mm, and volcanic dust particles are less than 0.06 mm in diameter. Volcanic blocks, also known as bombs, are the largest pieces of tephra and are more than 64 mm in diameter (baseball size or larger) and may be as large as small cars.
What is a slab of volcanic rock called?
A slab of volcanic rock is called a "lava flow" or a "lava rock".
What are minute volcanic particles?
Minute volcanic particles are tiny fragments of volcanic ash and rock that are produced during volcanic eruptions. These particles can be carried by wind over long distances and have the potential to affect air quality, climate, and human health.
Is ash the gas of lava?
No. Volcanic ash is not gas. It is made of tiny solid particles of rock or glass formed either when molten rock is fragmented or when solid rock is pulverized by explosive eruptions. Gas from a volcano is simply called volcanic gas.
Volcanic particles about the size of a rice grains are called?
Volcanic particles about the size of rice grains are called volcanic ash. Ash is made up of small rock and mineral fragments that are expelled during a volcanic eruption.
The particles produced in volcanic eruptions are called what?
The pulverized particulates are called ash. Larger chunks of magma are called tephra.
What are volcanic rock particles ranging in diameter from .25mm to less than 5mm?
Volcanic rock particles in this size range are classified as either lapilli or volcanic ash, depending on their exact size. Lapilli are volcanic rock fragments between 2 mm and 64 mm in diameter, while volcanic ash particles are smaller than 2 mm.

What is ash cloud made of?
An ash cloud is primarily made up of tiny particles of pulverized rock, minerals, and volcanic glass. These particles are created from the shattering of solid volcanic rock during an eruption and can range in size from fine ash to large boulders. Ash clouds can be carried high into the atmosphere by volcanic plumes and dispersed over wide areas by wind.
What is a molten volcanic rock called?
igneous rock
A sheet of volcanic rock that protrudes into the surrounding layers of rock?
It's called a volcanic sill.
What is classifies into?
Cooled magma is turned into a plutonic igneous rock, eg. Granite (you can see the difference between plutonic and volcanic because plutonic have large crystal particles)
Why does volcanic rock magnetize?
Volcanic rock, especially basalt, contains some iron. When the rock is still molten the particles of iron are free to move, but are influenced by Earth's magnetic field. When the lava hardens into rock these iron particles are locked in place, essentially recording the orientation of Earth's magnetic field.
