What is a cone-shaped mountain that is built from layers of lava?
A cone shaped mountain that is built from layers of lava is called a volcano.However, that description does not quite fit any of the three accepted descriptions of the world's volcanoes.A dome shaped mountain built from layers of lavais called a 'shield volcano'.A cone shaped mountain built from layers of cinders (tephra) is called a 'cinder cone' or a 'cinder cone volcano'.A cone shaped mountain built from alternating layers of lava and cinders is called a 'composite volcano'.
A volcanic mountain with gently sloping sides built almost entirely out of basalt lava flows is called a cinder cone.?
The Answer is false/untrue. A basaltic volcano with gently sloping sides is sometimes refrred to as a 'shield' volcano.
What is the difference between cinder cones and spatter cones?
A spatter cone is formed of molten lava ejected from a vent of a volcano. Expanding gases in the lava fountains tear the liquid rock into irregular gobs that fall back to earth, forming a heap around the vent. The partly liquid rock splashes down and over the sides of the developing mound is called spatter. Because spatter is not fully solid when it lands, the individual deposits are irregular in shape and weld together as they cool, and in this way differ from cinder and ash. A cinder cone is a volcanic cone built almost entirely of loose volcanic fragments called cinders. 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. Most cinder cones have a bowl-shaped crater at the summit.
Is the rock Scoria found in the US?
Yes,Scoria (a type of Basalt) Basalt is a dark-colored rock that formed as lava cooled and hardened. Scoria is a type of basalt that's full of bubble holes. The bubbles formed as the lava was blasted out of a volcano, and were trapped as the lava cooled and hardened.
What type of volcano is built almost entirely from ejected lava fragments?
Cinder Cones
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.
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 cones produce lava flows?
Yes. Although its typical eruptions produce simple lava flows, there have been cases where water came in contact with magma, triggering explosive eruptions with pyroclastic flows.
Why does a cinder cone volcanoes have such steep sides?
when lava flows down it the lava that stayed on it gets hard
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 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 type of lava does a cinder cone volcano have?
A cinder cone volcano has basaltic lava.
What is the lava of cinder cone volcanoes?
A cinder cone has basaltic lava, which has a fairly low viscosity.
What are the 4 types of volcanoes which exist and what type of lava do they produce?
shield, cinder cone, composite, and dome. They produce basaltic lava, rhyolite lava and andesite lava.
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.
What color is the lava of cinder cone volcanoes?
The color of cinder cone volcanoes is a blackish-gray.
