Introduction
Have you ever seen a volcano and wonder how it came to be???
Volcanic Facts !!!
- The volcanic ocean ridge is the longest mountain belt in the world !
- Some geologists believe that the continents grew out of volcanoes rising from the sea floor !
How A Volcano Is Formed !!!
The way a volcano is formed is when molten magma is forced through cracks in the earths crust,it cools in layers.The layers form a cone shape over time witch is a volcanic mountain.
What A Volcano Can Do !!!
One thing a (underwater) volcano can do is cause earthquakes and tsunamis.Another thing a volcano can obviously do is bring lots and lots of destruction.The way it explodes is by magma from the earths core reaches the surface now it is called lava.magma with a lot of gas can build up pressure witch makes an explosion with pyroclastic flows.
Definitions
- pyroclastic = composed chiefly of fragments of volcanic organ
- magma = molten material within the earths crust
