on the outside they are all made of cooled hardened lava
at least on the surface & normally down to some depth below the surface too
but sometimes they are made of ash as well
often in alternating layers
but below the lava & ash they are generally made of the same great variety of stuff the interior of the earth is made of everywhere else on the planet

What type of volcanoes are the hawiian islands?
The Hawaiian islands are made of two types of volcanoes, shield volcanoes and cinder cone volcanoes. Shield volcanoes have broad bases with gentle slopes. Cinder cone volcanoes have steeper sides, are made from fragments of lava, and are usually located at the base of shield volcanoes.
Do shield volcanoes have a steep sloping cone made up of rocks and lava?
No. Shield volcanoes have gentle slopes composed almost entirely of cooled lava flows.
Why are composite volcanoes steeply sloped?
It depends on viscosity of the lava. the runnier the lava, the farther it flows before solidifying, so it cannot pile up as fast.
What are volcanoes with gentle slopes and quiet eruptions?
stalkers
What are volcanoes with gentle slopes that cover large areas and occur in Hawaii called?
Shield volcanoes
What are the three life cycles in a volcano?
Three different types of volcanoes are: 1) Shield volcanoes; they are large mountains with gentle slopes. 2) Cinder cones volcanoes; they are small volcanoes made of hardened lava chunks called cinders. 3) Composite volcanoes; they are medium sized mountains made up of layers of lava that alternates with cinders.
The three types of volcanoes?
Shield volcanoes are the largest of the three types of volcanoes, built from basaltic lava flows and shaped like a gentle dome. Cinder cone volcanoes have very steep slopes and reach heights of 300 meters or less, and are made from ejected lava. Composite Cone Volcanoes are large symmetrical cones made from viscous lavas that are extruded, and they are the most violent volcanoes of the three.
What type of eruption produces a gentle flow of lava?
Shield volcanoes produce fast flowing lava. They erupt frequently, but eruptions are gentle because the lava is so thin and does not trap gas in the volcano.
Why do shield volcanoes have steep sides but are still very tall?
shield volcanoes have gentle sides and aren't very tall
How does cider cone volcano and shield volcano differ?
Cinder cones are small and steep-sloped, composed of volcanic cinders, and have mildly explosive eruptions. Shield volcanoes are large and shallow-sloped with very runny lava and generally non-explosive eruptions.
What is similar about cinder cone volcanoes and shield volcanoes?
Both shield volcanoes and cinder cones erupt low-viscosity basaltic lava and have eruptions that are only mildly explosive if at all.Cinder cones are small, steep-sloped volcanoes composed primarily of a chunky variety of basalt called scoria.Shield volcanoes are large, gently sloping volcanoes composed primarily of layers of lava flows.
Where are volcanoes made?
All volcanoes are made of gas and magma.
