Layers of ash and lava refer to the various levels of volcanic material deposited during an eruption. Ash is composed of small fragments of volcanic rock, while lava is molten rock that flows out of a volcano. Together, these layers provide a record of the volcano's eruptive history and can help scientists understand past volcanic activity.
A layer of ash and lava is a geologic feature formed by the deposition of volcanic ash and solidified lava during volcanic eruptions. These layers can build up over time to create thick sequences of volcanic material, which can be preserved in the rock record as distinct stratigraphic units.
Eyjafjallajökull is a stratovolcano, which is a steep-sided volcanic cone made up of layers of lava and ash. It is located in Iceland.
Mount Fuji is the archetype of the stratovolcano and probably rivals Vesuvius for the best-know volcano. The volcano rises about 3,500 m above the surrounding plain. Fuji has erupted at least 16 times since 781 AD. Most of these eruptions were moderate to moderate-large in size.
It is a stratovolcano, so it has a conical shape
A stratovolcano is a tall cone-shaped mountain formed by alternating layers of ash and lava during eruptions. These types of volcanoes are known for their explosive eruptions and steep sides due to the viscosity of their lava. Examples include Mount Fuji in Japan and Mount St. Helens in the United States.

Composite
The definition is: Where the lava and volcanic ash escape
Composite VolcanoesComposite Volcanoes. Composite volcanoes are tall, cone shaped mountains in which alternate layers of lava alternate with layers of ash. This happens when smooth lava flows alternate with explosive eruptions of lava fragments.
Ash
A stratovolcano is made of layers of tephra and lava. Stratovolcanoes are steep-sided and composed of alternating layers of volcanic ash, tephra, hardened lava flows, and other volcanic materials.
A mountain formed by the build up of lava and ash is a composite volcanic cone.
a volcano
The composite volcano.
The different layers of a volcano are made from the lava and ash produced by the volcano. Some volcanoes have different thicknesses of layers or only one type of layer depending on the kind of eruption and how much ash it produces.
Stratovolcanoes primarily consist of layers of solidified lava and tephra, which is a powdery substance consisting of ash, volcanic rock fragments, and pumice. These alternating layers of lava and tephra form the characteristic composite cone shape of stratovolcanoes due to their explosive eruptions.
