The Earth's crust is broken into 17 major, rigid tectonic plates.These float on a hotter, softer layer in its mantle.Volcanoes are often found where tectonic plates are moving apart or coming together. Likewise, there are elements of the volcanoes once an eruption has occurred, such as lava, the emission of gases through vents, the expulsion of volcanic bombs, which are usually large rocks, and ash clouds. This debris flies upward when the mountain bellows and falls after in the form of a pebbly rain that you'd better take shelter from. The Earth's crust is broken into 17 major, rigid tectonic plates. ash cloud - an ash cloud is the cloud of ash that forms in the air after some volcanic eruptions. Vent~an opening, as in a wall, serving as an outlet for air, smoke, fumes, or the like. The lava exits through the crater, the hole that cracks the mountain's peak. So it forces its way up “fissures” which are narrow cracks in the earths crust.Once the magma erupts through the earth’s surface it’s called lava. The diagram below shows how magma pushes up between the two plates: The magma chamber is a collection of magma inside the Earth, below the volcano… Select from premium Volcano of the highest quality. A volcano that consists of a complex of two or more vents, or a volcano that has an associated volcanic dome, either in its crater or on its flanks. When they explode in the air, it rains ashes and spews sediment. When a volcano erupts, it’s spewing forth lava, ash and hot rock. The world’s largest, active volcano is Mauna Loa in Hawaii, where famous coffee is grown in the rich volcanic soils. To a novice eye, this could look just like the cone, when in reality, the peak's mouth is much larger. Active volcano: a volcano that has erupted in the past 10,000 years, may be currently erupting, and is expected to erupt again. These are their main characteristics: Unlike other types of volcanoes, the strombolian variety spews denser lava and amasses so much gas underground, that the pressure can cause subterranean explosions. So, it starts piling up and covers the edges of the crater without spreading, shaping the mountain's appearance and even making it seem taller if the fireproof material it spits cools off. In turn, the lava is so thick that it ends up solidifying quite quickly, although it generates gas internally that comes out in the flowing lava rivers. vent - a vent is an opening in the Earth's surface through which volcanic materials erupt. Let's explore the different parts of a volcano and how they function. This is the passageway that links the magma chamber to the exit that the magma spews out of, along with the gases expelled when the volcano begins to erupt. A volcano is a vent through which molten rock and gas escape from a magma chamber. Summit - Highest point; apex . A subsidiary volcano may form from the main body, this is called a Parasitic cone. A volcano is formed out of eruption of lava from the crust of the earth. Crater~a bowl-shaped geological formation at the top of a Lava - Molten rock that erupts from a volcano that solidifies as it cools. The width of the magma chamber ranges from just a few kilometers up to dozens wide (they've documented some with more than a 70-kilometer radius). The image below shows the different parts of a volcano. As it exits the vent and flows out, this mass of melted stone changes in its original composition since it gets mixed with toxic gases and debris.

Crater - Mouth of a volcano - surrounds a volcanic vent. The name for these is 'fissure vents,' and they can appear on the cone's surface or far from the center of the eruption, several kilometers away. Vent - An opening in Earth's surface through which volcanic materials escape. Aside from the "volcanic cone" (i.e. However, the magma doesn't always make its way outside. From its base below sea level to its summit, Mauna Loa is taller than Mount Everest. A usually cone-shaped mountain formed by the materials issuing from such an opening. There are also branch pipes along the pipe going upward when the pipe cannot handle all of the lava as it moves upward. Detailed definition of Compound Volcano Pressure builds, and when the plates finally give and slip, energy is released as seismic … During this type of volcanic eruption, due to its compact nature, the lava flows out slowly down the sides and stays near the crater since it doesn't move enough.

In volcanology, magmatic dikes are the internal gaps that appear as the magma makes its way through to the Earth's surface. With this definition, an active volcano could be erupting right now or might have erupted only once since the last Ice Age. Formed millions of years ago by explosions in the mountain that fractured the top of the vent, of all of the parts of a volcano, the crater is the one that gives this geological formation its identifiable appearance.

The difference between lava and magma is that lava becomes magma upon leaving the volcano when it erupts. However, the sheer density of the lava can end up tapping the exit, causing these emissions to open new fissure vents across the Earth's surface, making the air unbreathable in the area. The sum-of-the-parts valuation (SOTP) is a process of valuing a company by determining what its aggregate divisions would be worth if they were spun off or acquired by another company.

As you can see, there is a pretty big window for active volcanoes. Some volcanoes are tall cones and others are just cracks in the ground (figure 1).As you might expect, the shape of a volcano is related to the composition of its magma.
