What statement is not true about cinder cones?
They do not produce lava flows.
What materials do cinder cone volcanoes produce?
Cinder cones produce ash and chunks of lava rock called scoria.
Do cinder cones erupt felsic or mafic lava?
Composite volcanoes can erupt both mafic and felsic material, but intermediate material is the most common.
What type of lava do cinder cones have?
Basaltic. There is more gas content than in most basaltic magma so that when a cinder cone erupts, The pressure builds up and makes the eruption somewhat explosive. Tephra, or dried lava/magma, is shot up, and joined to the volcano making it larger.
What type of lava does a cinder cone volcano have?
A cinder cone volcano typically has basaltic lava, which is low in silica content and flows easily. This results in the formation of steep-sided cones made of mostly cinders and volcanic ash.
Does a cinder cone produce lava flows?
Yes, cinder cones can produce lava flows. Typically, these flows are relatively short and are composed of basaltic lava. Cinder cones are formed from the accumulation of volcanic cinders and ash around a central vent.
What statement is not true about cinder cones?
They do not produce lava flows.
Is hot gases the only thing that come out of a cinder volcano?
No. Cinder cone volcanoes erupt fountains of lava, which is how the cinder cone is built up. Cinder cones that are nearing the end of activity may also produce lava flows.
What materials do cinder cone volcanoes produce?
Cinder cones produce ash and chunks of lava rock called scoria.
Why does a cinder cone have steep sides?
Cinder cones are not made from lava flows. They are made of fragments of righ that have piled up and rest at their angle of repose.
Do cinder cones erupt felsic or mafic lava?

How are cinder cone volcanos same as shield volcanos?
Both cinder cone and shield volcanoes are primarily composed of basaltic lava flows. However, cinder cone volcanoes are characterized by steep slopes, smaller size, and built up from pyroclastic material like ash and cinders, while shield volcanoes are much larger with gentle slopes built from numerous lava flows.
Are hot gases the only material that can come out of a cinder volcano?
No. Cinder cone volcanoes also fountain lava into the air and may produce lava flows as activity is coming to an end.
Do cinder cone volcanoes have AA lava or pahoehoe lava?
Pahoehoe and a'a refer to different texutres of lava flows. Although cindercones can produce lava flows, their main mode of eruption is called "fire fountaining" which tends to produce chunks of lava called scoria, rather than pahoehoe or a'a.
What are the kinds of cone volcanoes?
The two main types of cone volcanoes are stratovolcanoes and cinder cone volcanoes. Stratovolcanoes are large, steep-sided volcanoes composed of layers of lava flows, ash, and volcanic rocks. Cinder cone volcanoes are smaller, symmetrical volcanoes formed from pyroclastic material ejected during eruptions.
