A tephra cone volcano, also known as a cinder cone volcano, is made entirely of tephra. Tephra is a term for fragmented material produced by a volcanic eruption, such as ash, cinders, and bombs. Tephra cone volcanoes are typically small in size and have steep slopes due to the build-up of tephra fragments from explosive eruptions.
Composite
Paricutin Volcano in Mexico is a rare example of a volcano that is entirely made of tephra, which are fragments of volcanic rock ejected during an eruption. It emerged in 1943 from a cornfield and grew rapidly, reaching a height of over 1,300 feet before becoming dormant in 1952.
A combination volcano develops from repeated lava eruptions and the accompanying tephra deposits Tephra is the debris from the eruption..
Tephra
cinder cone volcano
A cinder cone volcano forms from tephra eruptions. Tephra consists of volcanic matter like ash, cinders, and volcanic rocks exploded into the air during an eruption, which then settle around the vent to form a steep-sided cone-shaped structure.

Cindercone
Tephra is basically ash, rock, cinders, and solidified lava spurted from a volcano.
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.
