I support volcanoes, because they are mountains filled with boiling lava. Volcanoes are more deadly because of the magma that is always building up inside of the volcano. Volcanoes can erupt in two ways it can explode, or flow like a rapid river. Volcanoes have tubes or channels underground that travel down and carry magma with them. Volcanoes can be dormant, active, or extinct. The most lethal volcanoes are super-volcanoes, an example is Yellowstone, Wyoming. The volcanoes are more deadly because of disastrous outcomes, such as they are uncontainable. When a volcano erupts it spreads for a 20 to 30 mile radius. That is why my vote goes to volcanoes, links used
