The reason I do this one first is that you may hit the sides of the. intake flange with the collet, leaving some small gouges in the material â see the second picture below. Doing the. inside cut first allows you to remove any collet gouges in the second cut that opens the runner side.
Composite Volcano. A composite volcano forms in subduction zones when a crustal plate is forced into the mantle and begins to melt. Andesite, dacite and rhyolite lavas are the primary types of lava that form these volcanoes.Eruptions on the volcanoes often alternate between tephra and lava flows. Subduction zone volcanoes.Geologists often use the term stratovolcanoes to describe the mountains that form in subduction zones.he melting oceanic crust forms pools of molten rock in a magma chamber. The magma, molten rock, in the magma chamber is lighter than the volcano rocks that surround it. The magma works its way to the summit where it erupts as tephra or in thick lava flows. Lava eruptions on stratovolcanoes.
Best Answer: Shield volcanoes are formed primarily by lava flows. This results in smooth sloping sides that resemble a convex shield laying down, facing up. Cinder Cone Volcanoes are formed primarily by ejected solid matter. This makes steep sides that make the volcano more conical. Composite volcanoes exhibit a mixture of ejected rock and lava flows. So they are something in between, a volcano not as steep as cinder cone volcanoes but still somewhat conical.
