They are called volcanic bombs.
This is called a volcanic bomb.
Blocks is the name used for the biggest pieces of tephra. Tephra is produced by a volcanic eruption.
Dust is less then 0.25 in diameter, ash is larger then dust but less then 2 mm in diameter, and the somewhat larger tephra are called lapilli which are larger than dust but less then 64 mm in diameter.
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.
The pulverized particulates are called ash. Larger chunks of magma are called tephra.
If you are referring to the crossword puzzle clue, a medium sized tephra is also known as lapilli.

King or Queen sized.
Tephra, the material ejected into the air during an explosive volcanic eruption, consists of molten lava materials such as pumice, cinders, and volcanic ash that have cooled and solidified as they fell through the air. Large tephra deposits form where the material lands and eventually become compacted into rock called volcanic tuff.

The smallest size of volcanic tephra is Ash, particles smaller than 2 mm (0.08 inches) in diameter.
Yes, extra large tires are referred to as plus sized. The correct industry term is wheel plus sizing. I do not think the tire would mind being called fat.
The rails, or Rallidae, are a large family of small to medium-sized birds.
The pulverized particulates are called ash. Larger chunks of magma are called tephra.
The large island near the southern tip of Italy is called Sicily, while the similar-sized one to Italy's west is called Sardinia.
