Volcanoes and the Ring of Fire

Volcanoes. In your mind, you just thought of lots of lava oozing out and hardening into magma and an eruption right? That's what I think of when I think of volcanoes too. Some people don't know the answer to this simple question. What is a volcano? There's more than just to a volcano erupting and volcano oozing out and turning to magma. You've got a lot to learn!
Volcanoes are an open mouth that leads down to an underground full of lava. When pressure builds up, eruptions occur. Rocks, gas, and lava shoot out. Once the lava has ben set on the ground, it cools and turns into magma! Hard rock. Why do volcanoes erupt? There are plates underneath the earth that move. When two plates collide, one of the plate goes on top of each other. This causes the lava to move upwards and erupt like a volcano.

Sure, but where do volcanoes come from? Volcanoes are formed from convergent boundaries. When two plates collide magma seeps through forming volcanoes!

The Ring of Fire is a ring of intense seismic and volcanic activity stretching from New Zealand, along the eastern edge of Asia, north across the Aleutian Islands of Alaska, and south along the coast of North and South America. It is composed over 75% of the world's active and dormant volcanoes.The Ring of Fire is located along the borders of the Pacific Plate and other tectonic plates but was noticed and described before the invention of the plate tectonics theory.
