Definitions
Ash rock is a type of rock that is formed from volcanic ash. It is composed of small particles of volcanic glass, minerals, and other materials that are ejected from a volcano during an eruption. This type of rock is often light in color and has a porous texture.
Origin
Ash rock is formed when a volcano erupts and ejects volcanic ash into the air. This ash can travel long distances before settling on the ground and forming a layer of sediment. Over time, this sediment can become compacted and cemented together to form ash rock.
Meaning in different dictionaries
According to the Merriam-Webster dictionary, ash rock is “a rock composed of volcanic ash and other materials that have been compacted and cemented together.”
The Oxford English Dictionary defines ash rock as “a rock formed from the consolidation of volcanic ash.”
