How many major volcanic erutions occur each year?
About 50 to 70 eruptions happen each year around the world. Some are are big eruptions while some of them are small.
How is a volcano born?
A volcano is formed when plates hit each other. One of the plates goes under the other. This is where the earth heats and melts the rock into magma and gases. This can happen as deep as 100 miles below the earth. Magma settles in pools or chambers near the surface. This is where eruptions take place. Volcanoes can also be formed when the plates go away from each other. The magma pushes up and lava forms. These types of volcanoes are found on the ocean floor.
What will happen if two plates crashed into each other?
If two plates crashed into each other two possible things can happen: 1 The plates bump into each other and can cause an earthquake. 2 The plates crash, then they go upwards to form a mountain or a volcano. ~Doraexplorer

How did mount st helens form?
Well, since it is a stratovolcano, is built up of alterning layers of lava and ash or cinders. These layers were made up over time by eruptions of the volcano.Basically, each time it erupted it made a new layer, and over time it started to look like a mountain (volcano).

Why do volcanoes erupt a lot in Washington Hawaii and California?
Frequency of volcano eruptions is related to the frequency of tectonic plates under the volcano diverge or converge (move away from each other, or collide with each other). I suppose that means that in Washigton Hawaii and California there is more tectonic plate activity than other places with volcanos that don't erupt or erupt on lower frequency.
