Smaller volcanoes that typically throw ash into the air during eruption
A
cinder cone
B
shield
C
composite
D
fissure
Explanation: 

Detailed explanation-1: -Cinder cones are also known as ash cones. Cinder cones are the type of volcano that is formed by pyroclastic fragments like volcanic ashes, solidified lava pieces, volcanic clinkers, pumice and hot gases. These volcanoes are formed around the volcanic vent and are known to be the simplest form of a volcano.

Detailed explanation-2: -Layers of Ash and Cinders Cinder cones are made up of layers of pebble-sized or larger cinders and layers of ash. Larger volcanic bombs and blocks may also be present.

Detailed explanation-3: -Cinder cones are typically are made of piles of lava, not ash. During the eruption, blobs ("cinders") of lava are blown into the air and break into small fragments that fall around the opening of the volcano. The pile forms an oval-shaped small volcano.

Detailed explanation-4: -Cinder cones are the simplest type of volcano. They are built from particles and blobs of congealed lava ejected from a single vent. As the gas-charged lava is blown violently into the air, it breaks into small fragments that solidify and fall as cinders around the vent to form a circular or oval cone.

Detailed explanation-5: -Cinder cones get their name from the material that forms them, cinders. Cinder cones are the simplest volcanic formation. They form from explosions of red, hot magma cinders and ash. These cinders and ash settle around the main vent and build a steep sided cone.
