Valconoes case study on Kilauea in Hawaii
Introduction
My case study that I will be doing will be on the
volcano called Kilauea which is in Hawaii. In
this presentation will be showing pictures, and
giving information about the volcano Kilauea.

From Magma to Lava
The rocks melt because of the extremely high
temperatures and pressure, which will become
liquid rock or magma. The large body of magma
that has been formed, it rises through the denser
rock layers towards Earths surface. Lava is
magma that has reaches the surface.
Lava Types
Magma comes in different compositions and
flavors. They will all produce a different
lava, more viscous andesite, fluid and fast
moving basalt to slower. Rocks melt in different
temperatures they are made up of collections of
minerals. The make-up of the rock being melted
affects the magma that results.

Can we Predict a Volcanic Eruption?
In the world that we live in, there are many
active volcanoes. As the population grows more
and more people are living in dangerous volcanic
areas. As we speak the volcanic eruptions
continue and as throughout history posing even
greater threats to life of property.
How do Volcanoes Form?
There is a solid body of rock called the mantle,
which is deep inside the earth between the molten
iron core and the thin crust at the surface.
Volcanoes erupt when pent-up gasses are released
the rock from the mantle melts, it will move to
the surface through the crust. Ask yourself but
why does this solid rock melt and come to the
surface.
