Lava, ash, smoke, and rock
A crater is not a separate material or part of a volcano. It is a depression or hollow at the summit of a volcano that forms when the volcano erupts and releases magma, gases, and other materials. The crater is a result of the collapse or expulsion of material during the eruption.
The three main types of volcanoes are shield volcanoes, cinder cone volcanoes, and composite (or stratovolcanoes) volcanoes. Shield volcanoes have gently sloping sides and are formed by layers of lava, while cinder cone volcanoes are steep-sided with a conical shape and are made of pyroclastic material. Composite volcanoes are a mix of both lava and pyroclastic material, with a classic symmetrical cone shape.
A conical volcano is a volcano with a classic triangular shape, formed from layers of lava, ash, and other volcanic debris. These types of volcanoes, such as Mount Fuji in Japan, typically have steep slopes and a conical appearance due to their eruptive style.
The substance that alternates with lava in a composite volcano is pyroclastic material. This material includes various types of fragmented volcanic rock, such as ash, cinders, and volcanic bombs. It is ejected during explosive eruptions and can be deposited around the volcano, building up layers over time.
The weakest type of volcano is known as a "cinder cone" volcano. These volcanoes are typically small in size and are formed from ejected volcanic material that builds up around the vent. They have short eruption periods and are not as explosive as other types of volcanoes.
The general term for the different types of material that a volcano spews out is ejecta.

Cinder Cone Volcano
The weakest type of volcano is known as a "cinder cone" volcano. These volcanoes are typically small in size and are formed from ejected volcanic material that builds up around the vent. They have short eruption periods and are not as explosive as other types of volcanoes.
When a volcano erupts, molten rock reaches the surface as lava, ash, or similar material. This is addes to the surface of the volcano. So the mountain or edifice of a volcano is essentially a pile of material that has erupted in the past.
A cinder cone volcano is often the product of gas-rich basaltic magma erupting explosively, forming loose pyroclastic material like cinders and ash. These volcanoes have steep slopes due to the eruption style, and they typically have a relatively short lifespan compared to other volcano types.
Cinder is a kind of volcano...a steep and active volcano :D
I really need to know what are the three main types of volcanoes??? A:the three main types of volcanoes are: active volcanoes dormant volcanoes extinct volcanoes -shiv kumar.v
