Answer:

.Volcanoes erupt in different ways, producing different landforms. Steep, cone-shaped volcanoes form when plates collide. ... When plates pull apart, lava escapes through the rift. This more gentle flow creates new crust on the seafloor and wide, rounded volcanoes on the surface called shield volcanoes.

. Molten rock is less dense than the surrounding rock, so it is buoyant and rises, just like hot air. Each eruption can produce layers of lava that will later become volcanic rock. These layers build the volcano. ... This material piles up right around the volcano, forming a steep cone, a classic volcano shape.
