Many events occur before and after a volcano erupts with a series of
explosions. The eruption creates a hole in the top of a mountain or hill. The
surface of the earth is made up of huge rocks called plates. When these plates
move back and forth, they hit one another. The center, or core, of the Earth is so
hot that the rocks are liquid. Melted rock, called magma, is pushed to the
surface from deep within the earth by the pressure from hot underground gases.
In most eruptions, magma flows out of the crater, turns into lava, and travels
down the sides of the volcano.
When Mount Vesuvius erupted, the magma turned to a hot spongy rock as
soon as it blew out of the top. In addition to the pumice, out came super-hot
poisonous gases and ash. The gases and ash looked like huge clouds.
Even though volcanoes cause mass destruction, they can also help our Earth
long after the eruption. Sometimes important metals like tin and gold come
closer to the surface of the earth after a volcano erupts. They can be mined and
used. Diamonds also are found. The spongy stone pumice is used today by
dentists to clean teeth.
There are also important minerals in the dangerous ash that settles over
everything. The ash fertilizes plants, and they become healthier. Let’s not forget
that the beautiful islands of Hawaii were formed by erupting volcanoes.
