2. Volcanoes: Nature's Fury Unleashed -
An E ploration of Their Formation,
Types, and Impacts

3. Volcanoes are geological formations that
have fascinated humans for centuries. They
are formed by the movement of tectonic
plates and can take on many different forms,
from shield to stratovolcanoes. The
eruptions of volcanoes can have devastating
impacts on both the environment and
human populations. In this presentation,we
will explore the formation, types, and impacts
of volcanoes.
Introduction

4. Volcanoes are formed by the movement of
tectonic plates. When two plates collide, one
plate is forced beneath the other, creating a
subduction zone.As the plate is subducted, it
melts and forms magma. This magma rises to
the surface, creating a volcano. The type of
magma and the type of volcano that is
formed depend on the composition of the
magma and the type of eruption.
Formation of Volcanoes

5. There are three main types of volcanoes:
shield,stratovolcanoes, and calderas. Shield
volcanoes are formed by the eruption of low-
viscosity lava, which spreads out in a wide
area.Stratovolcanoes are formed by the
eruption of high-viscosity lava, which piles up
in a steep-sided cone.Calderas are formed by
the collapse of a volcano after a large
eruption.
Types of Volcanoes

6. Eruptions and Impacts
Volcanic eruptions can have both immediate
and long-term impacts. The immediate
impacts include ashfall, pyroclastic flows, and
lahars, which can be deadly for humans and
wildlife. The long-term impacts include
climate change, as volcanic ash and gases can
block out the sun and cool the planet.
Volcanic eruptions can also create new land,
which can be beneficial for agriculture and
wildlife.

7. There are many famous volcanoes around the
world,including Mount St. Helens in
Washington, USA, Mount Vesuvius in Italy,
and Mount Fuji in Japan.These volcanoes
have had major impacts on both the
environment and human populations. By
studying these volcanoes, we can learn more
about the formation, types, and impacts of
volcanoes.
Famous Volcanoes

8. Volcanoes are powerful geological formations
that have both fascinated and terrified
humans for centuries. By understanding the
formation, types, and impacts of volcanoes,
we can better prepare for and mitigate their
impacts. W hether we are studying famous
volcanoes or exploring new ones,there is
always more to learn about these forces of
nature.
