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 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.
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.
What are Frothy volcanic rock are called?
Pumice is a frothy, bubbly, light volcanic rock.
What are minute volcanic particles?
The tiny volcanic particles ejected from a volcano are rock fragments formed during explosive shattering of sticky magma. Particles called ash are fragments smaller than 2 mm in diameter and the finest ash, minute particles less than 0.06 mm in diameter, are called volcanic dust.
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.

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 dust come out of a volcano after it erupts?
The "dust" is called ash. Volcanic ash can form when explosions fragment magma into small particles or pulverize pre-existing rock.
Large angular volcanic fragments are called?
Volcanic fragments are small pieces of rock that come from a volcano. Fragments are usually thrown in the air during a volcanic eruption.
