What are the different types of volcanic cones?

There are several main types of volcanic cones: shield, creepy, composite and spray. All volcanoes are caused by bursting in the Earth's crust, which allow you to appear magma, hot gas and pieces of debris, sometimes explosive. The cone of the volcano is the accumulation of debris around the ventilation opening in the Earth's crust; The cones are classified according to the substances that contain and the way they are formed. Different volcanic cones also look different, so finding the type of cone of the volcano is extremely important, especially in populated areas. These cones are made of free volcanic fragments that accumulate in bulk around the ventilation opening when they are released. Cinder cones are very simple and can form very quickly; For example, Paricutin in Mexico has grown from a sudden to 1,100 feet (336 meters) of a volcano during the year. OHAREKS can vary in size and usually has several different types of volcanic material.

Shield volcano is formed when magma moves slowly and creates a large, slightly sloping volcanic cone. A well -known example of the shield volcano is Mauna Loa in Hawaii. The lava emitted by the shield volcano has a low viscosity, so it is easy to pour and these volcanoes can slowly form for a long time, with fresh lava deposits to the top of the elders. The volcanic cones of this type have a very low profile and look more like a giant warrior lying on the ground.

Volcanic spray cones are made of thick lava and magma, which forcibly explode around the ventilation opening and create drops of the material that connects when the Lava cools down. Spat cones are characterized by very irregular surfaces caused by large pieces of lava and other material. Fans of the Riserie NGS can be familiar with the spat cones because Mount Doom is a classic example.

Composite volcanic cones are caused by alternating layers of magma, fragments of rocks and ash. Often explode violent and unpredictably; InSuvius, Mount St. Helens and Mt. Shasta are examples of composite cones. Composite cones can also cause lahars, mud of volcanic ash, which can be quite devastating.

eventually discharging Magmy under the Earth's surface, which was not related to the volcano, is known as a lava dome. Lava domes are often formed in volcanoes or in their vicinity, but can also occur in other areas with high geological activity. The lava dome can be seen as pimples on the ground and, like pimples, can appear, sometimes quite explosive with the shower of incredibly hot gases, magma, ash and pieces of rock.
