Yes. If it doesn't erupt and never has erupted then it is not a volcano.
bi lava
because movement of tectonic plates
Usually both.
You've got to be kidding me. A volcano that erupts often is called a cinder cone volcano, a volcano that does not erupt at all is called a shield volcano, and a volcano that can erupt but doesn't is a composite volcano. Here is the chart. Cinder cone: eruption Shield: dead Composite: sleep Hope you use my answer wisely. NOOBS!
Shield Volcanoes erupt less violently and flows further then composite volcanoes. A composite volcano erupts more violently.
Generally shield volcanoes do not explode. They erupt in a non-explosive fashion, fountaining or oozing lava.
This is because of the time of volcano it is and the type of lava it excretes. A steep volcano will erupt with basaltic lava which is runny and can clog at the top. A shield volcano, however is different as the thick lava emitted just glops onward.
So far that time is zero. As of December 2016 the shield volcano Kilauea in Hawaii is erupting. It has erupted almost continuously since 1983.
They can erupt anytime, when magma rises from the mantle and spews out of the volcano.
It depends, a volcano can erupt once and never erupt again. Or, a volcano can erupt multiple times a day.
it wil have thin lava because the lava is "runny" and shield volcanoes are made from nonexplosive eruptions so they will be quiet when they erupt.
Both shield volcanoes and cinder cones primarily erupt basaltic lava.
