Each has a special shape. The first kind is called a cinder cone. As its name says, this volcano looks like a giant cone. These cinders settle all around the volcano. They form a cone.
Shield volcanoes erupt in different way.
Very liquid lava flows freely from the volcano's hole. The lava spreads far out around the volcano, making a mountain with a low, broad dome. The third kind of volcano is called a composite volcano. Both lava and bits of rock and dust erupt. These materials form layer upon layer around the volcano's hole.
