Hello everybody
Today I will write about a
phenomenon which is called VOLCANO
I got the information from a book I read and its title is
Tsunamis and Other Natural Disasters
By:Mary Pope Osbrne and Natalie Pope Boyce
The word volcano comes from Vulcan, the Roman god of fire
When we think of Volcanoes, we often think of cone shaped moutains spewing out fire and ash. But volcanoes come in different sizes and
shapes. Some are tall moutains
Others are cracks in the earth. Still others are gentle slopes with a crater on top. Volcanoes are a vent, or opening in the earth's crust. Hot melted rock erupts from the the vent. Cinder cones are the most common type of volcano. In an eruption, the lava is shot so high into the air that it cools into cinders
.
people can suffocate from poison gases.
They can beinjured or killed as rock and ash pound down on their heads as they try to flee
.At times, the eruption creates a deadly mixture of fast-moving hot gases and pieces of red-hot rock.In addition, volcanoes can change the climate, After a big eruption, volcanic dust drifts high into the sky and spreads out over the planet.The dust filters out the sun. The whole world feels the effect. Day become darker and colder.
Types of volcanoes
Shield volcanoes
They are very larg. The top looks like a giant bowl or shield
Cinder Cones
They are the most common type of volcano. In an eruption, the lava is shot so high into the air that it cools into cinders.
Composite volcanoes
Composite means "made up of different parts".They have thick lava that usually erupts violently
