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?
Composite volcanoes can erupt both mafic and felsic material, but intermediate material is the most common.

How are cinder cone volcanos same as shield volcanos?
A composite volcano is a combination of a cinder cone and a shield cone. The top of a composite volcano is steep like a cinder cone. The bottom of a composite volcano is flatter, like a shield volcano.
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?
There are three kinds of cone volcanoes shield cones, composite cones, and cinder cones. Shield cones have very fluid lava. They erupt with a quiet lava flow. An example of a shield cone volcano is Mauna Loa. A shield cone is pretty much a little dome that has been flattened. Composite cones have sticky lava and rock bits. They have the most explosive eruptions An example of a composite cone volcano is Vesuvius. Composite cones are steep at the top but gentle at the bottom. Cinder cones have cinders. They have explosive eruptions An example is Paricutin. A cinder cone is very steep.
