Volcanoes writing

~Volcanoes Writing~


What is a volcano? you say. Well, a volcano is an opening
in a mountain on the Earth's surface. A volcano can knock
down a whole forest. A volcano allows hot lava, ash, and
gas to escape from the magma chamber under the earth’s
surface. When a volcano erupts it lets hot ash. Mudflows,
floods, tsunami’s, and falling rocks can trigger.


Volcanoes are formed when magma within the earth makes
its way up to the surface. A volcano is made from tectonic
plates, which creates magma and it builds up when magma
erupts that is called lava. There are two types of tectonic
plates are called Oceanic and Continental plates.


Volcanoes are classified as active, dormant, extinct.
Active means that one of the volcanoes is able to erupt,
dormant is that when a volcano is sleeping and might
erupt again, extinct means it is likely to not erupt again.
Volcanoes can come in different shapes and sizes, they
mostly look like an upside-down ice cream cones or a ½
circle.


The earth's crust is made up of huge rocks called tectonic
plates. There two plates that surround the Pacific Ocean.
These plates are The Oceanic Plate and the Continental
Plate. When these plates rub together they melt and can
create molten rock. Subduction and friction occur which
causes earthquakes and volcanoes.


There are over 1510 active volcanoes in the world. There are
currently, 80 or more volcanoes are under the ocean. The
The United States ranks number 3rd in the world for the
number of active volcanoes. The United States is behind
Indonesia and Japan for having the most active volcanoes.
The reason there are a large number of volcanoes around
the Pacific is because of the Ring of Fire.
