Volcanic Blocks are solid, irregularly shaped lumps of hardened lava, often large and boulder like in appearance; some rare volcanic blocks may weigh many tons!
Fragmental volcanic material is often referred to as pyroclastic or tephra, which includes ash, lapilli, and larger volcanic blocks and bombs produced during explosive volcanic eruptions.
Tilted blocks of rock are commonly found in areas where tectonic forces have caused the Earth's crust to be uplifted and deformed, such as in mountain ranges, along fault lines, or in areas of intense volcanic activity. These tilted blocks can provide valuable information about the geological history and processes that have shaped the landscape.

The rigid blocks of Earth's crust and upper mantle are known as tectonic plates. These plates float on the semi-fluid asthenosphere and move due to the heat-driven convection currents in the mantle, leading to processes like earthquakes and volcanic activity.
Folded mountains - formed by the folding of rock layers due to tectonic plate movement. Fault-block mountains - formed by the movement of tectonic plates causing blocks of the Earth's crust to uplift. Volcanic mountains - formed by the accumulation of lava and volcanic ash from volcanic eruptions. Dome mountains - formed by the uplift of large areas of the Earth's crust without significant folding or faulting.
VOLCANIC ASH, VOLCANIC CINDERS, VOLCANIC BLOCKS & VOLCANIC BOMBS.
Volcanic blocks
The 4 different types of solid pyroclastics are volcanic bombs, lapilli, volcanic ash, and volcanic blocks
Shield volcanoes are formed by the relatively quiet outpouring of lava, which results in a broad and gently sloping shape. Volcanic blocks are typically associated with explosive eruptions that occur in stratovolcanoes, where gas pressure causes fragmented volcanic material to be ejected. As shield volcanoes tend to have less explosive eruptions, the formation of volcanic blocks on their slopes is rare.
cinders
Fragmental volcanic material is often referred to as pyroclastic or tephra, which includes ash, lapilli, and larger volcanic blocks and bombs produced during explosive volcanic eruptions.
Large blocks of reformed volcanic rock, surfaced with marble.
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 gasesI answered this earlier but this is a better answer ;)
Volcanic blocks
It blocks (some of) it from reaching the surface of the Earth.
The three types of non-boundary mountains are volcanic mountains, dome mountains, and fault-block mountains. Volcanic mountains form from volcanic activity, dome mountains are created by the uplifting of large blocks of crust, and fault-block mountains are formed when large crustal blocks are uplifted along faults.
a pyroclastic flow is a cloud of volcanic bombs, volcanic blocks, volcanic ash, and lapilli. these flows can achieve speeds at over 125 miles per hour and can be more than 750 degrees Celsius.
