Where can volcanoes occur? Volcanoes can also occur at hot spots, such as at the areas of the Hawaiian islands and Yellowstone in America. This type of volcano forms when magma from the mantle rises to Earth's surface through a certain spot in the middle of the plate (i.e., the Pacific Plate for the Hawaiian Islands).olcanoes usually occur where there are collision of the tectonic plates. There are 52 tectonic plates which either pull (gap and crack) or push (volcano). Volcanoes are actually tectonic plates which have magmas beneath their outer surface.

- What causes Volcanoes? Volcanic activity frequently occurs at the boundaries of the Earth's tectonic plates which are a series of large blocks moving between each other. The movement of these plates plays a significant role in the type of volcano formed, which influences its shape.

Why Do Earthquakes and Volcanoes Happen Mostly in the Same Place? Earthquakes and volcanoes occur in the same places because they both happen along the Ring of Fire. The Ring of Fire is located along the edges of a major tectonic... Earthquakes and volcanoes occur in the same places because they both happen along the Ring of Fire. The Ring of Fire is located along the edges of a major tectonic plate. Earthquakes are caused when tectonic plates shift and push over each other. The place where this happens is called a fault line.

Volcano A volcano is a rupture on the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface.Earth's volcanoes occur because its crust is broken into 17 major, rigid tectonic plates that float on a hotter, softer layer in its mantle.olcanic cones or cinder cones result from eruptions of mostly small pieces of scoria and pyroclastics (both resemble cinders, hence the name of this volcano type) that build up around the vent. These can be relatively short-lived eruptions that produce a cone-shaped hill perhaps 30 to 400 meters high.

Volcanic eruptions and environment On locations where tectonic plates diverge or converge, volcanoes can be found. A volcano consists of a deep magma chamber where magma accumulates, pipes that lead to surface vents, and the vents through which lava is emitted during a volcanic eruption.igure 1: layout of a volcano. Volcanoes that have not erupted for some time are dormant, and volcanoes that have not erupted even in the distant past are called extinct. Volcanic activity and volcanic eruption is usually triggered by alterations of tectonic plates, resulting in landslides or earthquakes.

Why do most volcanoes and earthquakes occur at plate boundaries? Most earthquakes and volcanoes occur because of the movement of the plates, especially as plates interact at their edges or boundaries. At diverging plate boundaries, earthquakes occur as the plates pull away from each other. Volcanoes also form as magma rises upward from the underlying mantle along the gap between the two plates.

Why do volcanoes erupt? Some people believe volcanic eruptions are caused by fate. Others believe a volcanic eruption is a sign that a mountain is upset because residents living nearby have sinned. But science has another explanation.ruptions from this process are hard to predict. Above the magma chamber. Eruptions can also happen due to loss of pressure above the magma chamber. This can be caused by various things, such as a decrease in density of rocks above the chamber or the melting of ice atop a volcano.

- An earthquake occurs when tension along a plate boundary becomes too great, the rocks slip releasing energy. When cracks form in the crust, or one plate slips beneath another building up intense pressure and heat, volcanoes can erupt. To understand volcanoes, students need to understand the plate tectonics connection.

How does plate tectonics affect volcanoes? It is most common to find volcanoes where an oceanic plate collides with a continental plate. It is the boundary between the Pacific Plate and the continental plates around it that is called the ring of fire because so many volcanoes are formed at this boundary.In the collision the denser oceanic plate will be forced underneath of the continental plate.This is called 'subduction', and it usually occurs in destructive plate boundaries. Volcanoes are then formed, when the oceanic plate melts and the molten rock rises, being squeezed up by the forces of the mass above.olcanoes are formed by any of three different geologic processes: The first one, which has little to nothing to do with plate tectonics, is the presence of a hot spot. A … hot spot is a specific area below the earth's crust in which there is an abnormally high pressure of magma (underground molten rock).

Volcanic Eruptions A volcanic eruption occurs when molten rock, ash and steam pour through a vent in the earth's crust. Volcanoes are described as active (in eruption), dormant (not erupting at the present time), or extinct (having ceased eruption; no longer active). Some volcanoes explode.

Why are there volcanoes? Why do they erupt? Category: Volcanoes are just a natural way that the Earth and other planets have of cooling off and releasing internal heat and pressure. Volcanoes erupt because of density and pressure. The lower density of the magma relative to the surrounding rocks causes it to rise (like air bubbles in syrup).

Volcano A volcano is a mountain where lava (hot, liquid rock) comes from a magma chamber under the ground. Most volcanoes have a volcanic crater at the top. When a volcano is active, materials come out of it. The materials include lava, steam, gaseous sulfur compounds, ash and broken rock pieces.When there is enough pressure, it causes the volcano to erupt. The pressure blows off the top of the volcano.ost volcanoes have a volcanic crater at the top. When a volcano is active, materials come out of it.

Why Do Earthquakes and Volcanoes Happen Mostly in the Same Place? The shifting of the plates causes movements on the surface of the Earth that feel like an earthquake, and as the plates are constantly in motion, they naturally bump against each other over time. Volcanoes are formed when magma from the interior of the Earth works its way up to the planet's surface.

What causes a volcano to erupt and how do scientists predict eruptions? Most recently, Professor Kilinc has been studying volcanoes in Hawaii and Montserrat. When a part of the earth's upper mantle or lower crust melts, magma forms. A volcano is essentially an opening or a vent through which this magma and the dissolved gases it contains are discharged.OLTEN ROCK, or magma, and gasses spew from the mouth of a volcano in the Hawaiian islands. As rock inside the earth melts, its mass remains the same while its volume increases--producing a melt that is less dense than the surrounding rock.

What Causes Volcanoes to Erupt? In some places of the crust, there are weak spots, places that are thinner than others. These are where volcanoes occur. In the mantle below, about 1,800 miles thick, gases can build up, and create outward pressure.

What Is a Volcano? The Sakurajima Volcano in Japan is one of the most active volcanoes in the world. Credit: Kimon Berlin. A volcano is an opening on the surface of a planet or moon that allows material warmer than its surroundings to escape from its interior. When this material escapes, it causes an eruption.An eruption can be explosive, sending material high into the sky. Or it can be calmer, with gentle flows of material.he Sakurajima Volcano in Japan is one of the most active volcanoes in the world. Credit: Kimon Berlin.

Volcanic Eruptions: What Causes Volcanoes to Erupt They may erupt violently like Krakatoa in 1883, or just seep out lava like the Kilauea volcano. Formed as a result of plate tectonics, volcanic eruptions can result in the formation of mountains, craters, crater lakes, plateaus, and islands.

The features of volcanoes are much more complicated and their structure and behavior depends on a number of factors.
