The aim of this paper is to analyse the different types of volcanoes in the lights of broad and diverse academic resources.
Magma contains hot gases, which make attempts to escape but are entrapped inside the magma Cambridge Encyclopedia, Overview Volcanoes are considered to be holes, gaps or vents that are present in the crust of the Earth.
The volcanic activity of shield volcano is continuous and common. Lyn Topinka — CVO Photo Archive They tend to form at subduction zones where one tectonic plate is sliding beneath the other — the oceanic plate beneath the continental plate. The lava blows into the air and its cooled pieces return and settle all over the vent.
Overview Volcanoes are considered to be holes, gaps or vents that are present in the crust of the Earth. Eruption velocity is controlled by the gas contents of the column, and low-strength surface rocks commonly crack under the pressure of the eruption, forming a flared outgoing structure that pushes the gases even faster.
This release of water pushes the magma towards the surface. Shield volcanoes have small amounts of pyroclastic material, most of which accumulates near the eruptive vents, resulting from fire fuming events.
Cinder Cone Volcanoes An easily recognized type of volcano is the cinder cone. Mauna Loa, a shield volcano on the pisland of Hawaii, is the largest single mountain in the world, rising over 30, feet above the ocean floor and reaching almost miles across at its base.
They form when the particles of the lava explode from the opening of the volcano. Photograph by Mark Thiessen, National Geographic. These are the classical Hawaii examples — steady flow and accumulation of lava leading to the shield-type formation.
This type of volcano can be hundreds of miles across and 10, feet high. The molten lava or magma is assembled in a cavity, which is found beneath the surface of the earth. Because of its linear nature, it is difficult to detect this type of volcano from ground as its surface is flat.
As the pressure increases at such a rate that it goes upwards by means of fissures or gaps and a channel to the top most layer of the earth is created.
The most popular shield volcanoes include Mauna Loa and Mauna Kea. Once the volcano explodes and all gathered energy is released, a new period of calm volcanic activity awaits. Volcanoes act differently and form differently because they are made up of different types of rocks and minerals.
These are the simplest type of volcano.Introduction to Tectonic Forces. Understand where earthquakes and volcanoes are located around the world and why.
Explain geologic structures that lead to folding and faulting of the physical landscape. Describe the various types of fault lines and volcanoes and the landforms they form. Types Of Volcanoes Essay Examples.

Composite volcanoes, or stratovolcanoes make up some of the world’s most memorable mountains: Mount Rainier, Mount Fuji, and Mount Cotopaxi, for example.
These volcanoes have a conduit system inside them that channels magma from deep within the Earth to the surface. The U.S. Geological Survey estimates that there are about 65 active volcanoes in the United States and its territories.
The Dynamic maps viewer (shown at right) provides an interactive presentation of potentially active volcanoes in the 48 continguous states.
Volcanoes are distinguished by their eruption style, composition, and structure. Several types of volcanic eruptions—during which lava, tephra (ash, lapilli, volcanic bombs and volcanic blocks), and assorted gases are expelled from a volcanic.
These three types of volcanoes that occupy the earth have seemingly different physical characteristics and behavioral changes.
A volcanic eruption is one of the most dangerous and eventful natural disasters that can take place.Download
