Shield Volcanoes (U.S. National Park Service) [1]
Although shield volcanoes are the largest volcanoes on Earth, they do not form soaring mountains with conical peaks like composite volcanoes. Instead, they are broad volcanoes with gentle slopes and are shaped somewhat like a warrior’s shield lying flat on the Earth
Shield volcanoes are truly massive with volumes that dwarf other types of volcanoes, even large composite volcanoes.. Shield volcanoes are usually constructed almost entirely of basaltic and/or andesitic lava flows which were very fluid when erupted
At least 13 national parks contain shield volcanoes, including:. Hawai’i Volcanoes National Park contains parts of Mauna Loa and Kīlauea, two of the most active shield volcanoes on Earth

Volcanoes: Principal Types of Volcanoes [3]
Geologists generally group volcanoes into four main kinds–cinder cones, composite volcanoes, shield volcanoes, and lava domes.. They are built from particles and blobs of congealed lava ejected from a single vent
Most cinder cones have a bowl-shaped crater at the summit and rarely rise more than a thousand feet or so above their surroundings. Cinder cones are numerous in western North America as well as throughout other volcanic terrains of the world.
In 1943 a cinder cone started growing on a farm near the village of Parícutin in Mexico. Explosive eruptions caused by gas rapidly expanding and escaping from molten lava formed cinders that fell back around the vent, building up the cone to a height of 1,200 feet
6 Volcanic Landforms – Open Petrology [4]
– Volcanic mountains may be shield volcanoes or stratovolcanoes.. – Shield volcanoes are much larger than stratovolcanoes
In contrast most composite volcanoes have diameters of 15-30 km.. – Geologists sometimes list caldera, lava domes, maars, craters, and cinder cones as additional kinds of volcanoes
– Most shield volcanoes are found on ocean islands above hot spots or on continents at continental rifts.. – Shield volcano eruptions commonly occur at a central vent, but flank eruptions and fissure eruptions are common on the slopes or even near the base of a volcano.
Plate Tectonics and Volcanic Activity [5]
A volcano is a feature in Earth’s crust where molten rock is squeezed out onto Earth’s surface. Along with molten rock, volcanoes also release gases, ash, and solid rock.
A volcano is a feature in Earth’s crust where molten rock is squeezed out onto the Earth’s surface. This molten rock is called magma when it is beneath the surface and lava when it erupts, or flows out, from a volcano
Volcanoes come in many different shapes and sizes but are most commonly cone-shaped hills or mountains. They are found throughout the world, forming ridges deep below the sea surface and mountains that are thousands of meters high
What type of volcano does not form a mountain? [6]
Did you know that not all volcanoes are formed in the same way? There are several different types of volcanoes, categorized by the method in which they are formed. These are the cinder cone volcanoes, composite or stratovolcanoes, and shield volcanoes.
Cinder cone volcanoes usually do not form mountains. They are cone-shaped hills that are formed when lava and cinders build up around the vent that…

What Are Different Types of Volcanoes? And Volcanic Eruptions [8]
A volcano is a land-form, a mountain, where molten rocks erupt through the surface of the planet. The volcano mountain opens downwards to a pool of molten rocks below the surface of the earth.
Gasses and rock shoot up through the opening and spill over or fill the air with lava fragments. The volcano eruption can cause lateral blasts, hot ash and lava flow, mudslides, and more.
An active volcano is one which has recently erupted and there is a possibility that it may erupt soon.. A dormant volcano is one that has not erupted in a long time but there is a possibility it can erupt in the future.
Types of volcano [9]
When magma erupts at the surface as lava, it can form different types of volcano depending on:. Strictly speaking there are two broad types of volcano, a stratovolcano and a shield volcano, although there are lots of different volcanic features that can form from erupted magma (such as cinder cones or lava domes) as well processes that shape volcanoes
An eruption of highly viscous (very sticky) magma tends to produce steep-sided volcanoes with slopes that are about 30–35°. That’s because the viscous volcanic material doesn’t flow that far from where it is erupted, so it builds up in layers forming a cone-shaped volcano known as a stratovolcano
When a shield volcano erupts, the basalt can flow great distances away from the vent to produce broad, gentle slopes.. Where a volcano produces low viscosity, runny lava, it spreads far from the source and forms a volcano with gentle slopes: a shield volcano
Volcanoes: The Nature of Volcanoes [10]
Volcanoes are mountains but they are very different from other mountains; they are not formed by folding and crumpling or by uplift and erosion. Instead, volcanoes are built by the accumulation of their own eruptive products — lava, bombs (crusted over ash flows, and tephra (airborne ash and dust)
The term volcano also refers to the opening or vent through which the molten rock and associated gases are expelled.. Driven by buoyancy and gas pressure the molten rock, which is lighter than the surrounding solid rock forces its way upward and may ultimately break though zones of weaknesses in the Earth’s crust
Larger fragments fall back around the vent, and accumulations of fall-back fragments may move downslope as ash flows under the force of gravity. Some of the finer ejected materiaIs may be carried by the wind only to fall to the ground many miles away
Where Does Volcanic Activity Occur? [11]
Myth: Most of the Earth’s igneous rocks are produced at the “Ring of Fire.”. Fact: 70% of the Earth’s surface is ocean floor, which is made of basalt, an igneous rock produced at mid-ocean ridges
Volcanic activity occurs at two types of plate boundaries: mid-ocean ridges and subduction zones. At mid-ocean ridges, basaltic eruptions produce new sea-floor crust
Commonly, basalt is erupted at mid-ocean ridges as blob-shaped “pillows.” These pillows form when basalt is suddenly quenched as it comes into contact with sea water. If you cut a pillow in half, you’ll find a glassy rind around the outside, where the lava cooled so fast that it couldn’t form any crystals
Types and Formation » Geology Science [12]
Volcanoes are holes in the earth’s crust through which molten rock and gases escape to the surface. Volcanic hazards arise from two classes of eruptions:
Explosions pose a risk by scattering rock blocks, fragments and lava at varying distances from the source.. Sudden explosions where the greater danger is the flow of material rather than explosions
Flows are governed by gravity, surrounding topography, and material viscosity.. Hazards associated with volcanic eruptions include lava flows, falling ash and projectiles, mudflows and toxic gases
Mountain formation [13]
Mountain formation refers to the geological processes that underlie the formation of mountains. These processes are associated with large-scale movements of the Earth’s crust (tectonic plates).[1] Folding, faulting, volcanic activity, igneous intrusion and metamorphism can all be parts of the orogenic process of mountain building.[2] The formation of mountains is not necessarily related to the geological structures found on it.[3]
From the late 18th century until its replacement by plate tectonics in the 1960s, geosyncline theory was used to explain much mountain-building.[5]. There are five main types of mountains: volcanic, fold, plateau, fault-block and dome
Movements of tectonic plates create volcanoes along the plate boundaries, which erupt and form mountains. A volcanic arc system is a series of volcanoes that form near a subduction zone where the crust of a sinking oceanic plate melts and drags water down with the subducting crust.[9]
Why Are Some Mountain Ranges Volcanic and Others Not? [14]
I was looking at the geology subreddit the other day and someone asked an intriguing question: why aren’t the Himalayas volcanic? They are the largest mountains on the planet and span thousands of miles but nary a volcano can be found. This might seem strange to many people as there are mountain ranges that are full of volcanoes — the Andes and the Cascades for example
Sometimes when they collide, you just build big mountains and other times you get mountains and volcanoes.. The Himalayas are enormous, running over 1,400 miles from end to end
Instead, they are built by the collision of two tectonic plates that has been going on for tens of millions years.. The Indian subcontinent and Eurasian are at odds with each other

– Describing the various types of volcanoes and the land-forms they create.. – Describing the hazards and benefits of volcanic activity.
Volcanoes are common along convergent and divergent plate boundaries, but are also found within lithospheric plates away from plate boundaries. Wherever mantle is able to melt, volcanoes may be the result.
Volcano – Plate Boundaries, Magma, Eruptions [16]
Earth’s tectonic plates, which move horizontally with respect to one another at a rate of a few centimetres per year, form three basic types of boundaries: convergent, divergent, and side-slipping. Japan and the Aleutian Islands are located on convergent boundaries where the Pacific Plate is moving beneath the adjacent continental plates—a process known as subduction
The East Pacific Rise is representative of a divergent boundary where the Pacific Plate and the Nazca Plate (west of South America) are moving apart—a process known as rifting.. Volcanoes occur along both subduction and rift zones but are generally absent along strike-slip plate margins
Subduction-related volcanoes erupt basalt, andesite, dacite, and rhyolite, andesite being the predominant rock type. Rift-related volcanoes, especially on the ocean floor, erupt mainly basalt.
Volcanic mountain ranges [17]
Volcanic mountain ranges represent thick segments of crust that formed by addition of thick piles of volcanic rocks, generally above a subduction zone. Examples of volcanic mountain chains include the Aleutians of Alaska, the Fossa Magna of Japan (including Mount Fuji), and the Cascades of the western United States (including Mount Saint Helens)
Many do have folds and faults, however, showing that there is overlap between fold and thrust types of mountain chains and volcanic ranges.
Power of Plate Tectonics: Volcanoes [18]
Some mountains are made of solid rock, like the Rocky Mountains or the Swiss Alps. Volcanoes are vents, or openings in Earth’s crust, that release ash, gases and steam, and hot liquid rock called lava
Most of the world’s volcanoes are found around the edges of tectonic plates, both on land and in the oceans.. On land, volcanoes form when one tectonic plate moves under another
When this happens, the ocean plate sinks into the mantle.. Water trapped in the rocks in this plate gets squeezed out

Are Volcanoes Mountains? [20]
A mountain results from various geological processes such as movement and opposition of tectonic plates. On the other hand, a volcano forms around a vent when magma flows out and reaches the surface of the earth.
Upon collision, tectonic plates form pointed peaks and valleys. The earth’s crust (outer layer) is composed of six massive slabs known as tectonic plates
When two tectonic plates move against each other and collide, the earth’s crust thickens and deforms. Due to the collision pressure, some of the land mass is pushed upwards forming a mountain.
Types of Mountains [21]
Mountains are formed by slow but gigantic movements of the earth’s crust (the outer layer of the Earth).. The Earth’s crust is made up of 6 huge slabs called plates, which fit together like a jigsaw puzzle
Many of the greatest mountain ranges of the world have formed because of enormous collisions between continents.. Earthquakes occur when two plates pushing past each other cause a fracture in the Earth’s crust.
In both cases, great areas of land are lifted upwards to form mountains. Other mountains are formed by the earth’s crust rising into a dome, or by volcanic activity when the crust cracks open.
Types of Volcanic Mountains [22]
Active Volcano: An active volcano erupts continuously in the present time. Example: Barren Island volcano at Andaman Nicobar Islands in India is the only active volcano of India
Stromboli in Italy or the ‘Lighthouse of the Mediterranean’ is one of the most active volcanoes on Earth.. Dormant or sleeping volcanoes: These are the most dangerous volcanoes in the world
Extinct Volcano: An extinct volcano is the one which has not erupted for the last 10,000 years and is a dead volcano according to scientists. An extinct volcano has no lava supply in its magma chamber
