Volcanos can be found in the ring of fire and in other parts of the world.Earthquakes can occur because of the tectonic plates they can move and make an earthquake it can be caused by volcanoes in the ring of fire which has a lot of volcanoes and earthquakes.

The melted rock, or magma, is lighter than the surrounding rock and rises up. This magma collects in magma chambers, but it is still miles below the surface. When enough magma builds up in the magma chamber, it forces its way up to the surface and  Thiserupts, often causing volcanic eruptions.

Volcanos form like when magma comes up from the earth it forms into rocks and when it erupts it becomes rock and when that happens it forms a mountain volcano like.

hen volcanoes erupt they can spew hot, dangerous gases, ash, lava and rock that can cause disastrous loss of life and property, especially in heavily populated areas.
When the volcano erupts, magma is drawn from the shallow storage area, and the ground above it subsides to fill the space. If a large amount of magma is withdrawn rapidly from the storage area, the ground will collapse, and this is the process in which calderas or pit craters are formed.
