Volcanoes are mountains but still they are
very different.
Volcanoes are formed by folding and crumpling
or by a uplift and erosion
A volcano is most commonly a conical hill of a
mountain built around a vent from the earth
connected to the resvoirs.
The term Volcano refers to the opening or
vent through rock.
The volcano built up by the pressure of
molten rock.
Larger fragments fall back around the vent
Volcanoes are built by the accumulation of
their own eruptive erosion.
Built up by the pressure of the molten rock.
Volcanoes are practically mountains that are
old and are used as vents to release the
molten rock from the core of the earth.
The molten rock builds up in the volcano and
the pressure gets to much it erupts.
There are three different stages of a Volcano
Shield, Conder core and composite Volcano. As
shown.

Earths surface follows the release for energy
Seismic waves travel outwards from the source of earthquakes
Some are high frequency and some are very low
This vibration cause the earth to move
A fault is the fracture in the earth crust and slipped rock.
These faults are divided into three – Normal Faults-is pulling or tension
-Thrust faults- squeezing of compression
-Strike Slip faults- Blocks move past each
other
After a earthquakes another can occur usually called a aftershock
These can occur hours later depending on how strong
Epicenter- a point of earths surface directly above the focus
Location of an earthquake is commonly described but the geographic position
Earthquakes beneath the ocean floor generate immense sea waves called
tsunamis

Mountains are formed in many ways
there are four
-volcanic
-Eros ional
-fault block
-folded
Volcanic mountains are also knows as
volcanoes
Mountains are a way of realeasing
internal heat
Erosional
Formed by wind ro water wearing down
weak spots in land
Non resistant material washed away
Fault block mountains
Formed by vertical faulting of large
blocks of earth
Folded mountains
Most common
Created by tectonic plate pushing
against each other-When two plates
move against each other and create
tension therefore the only direction
for these mountains to move up.
