Volcano Occur
The volcanic activity has a huge impact on the surface of the Earth’s crust. It is because solid, liquid, and gaseous substances find their way to the surface from some deep Reservoir beneath the surface of the earth.
Molten magma is a type of Rock that can move, and it forces its way into the Planes of weakness of the crust, which is where the Earth’s crust is a little bit weak. The magma pushes its way upwards through it. Magma, when it makes its way upward to the surface it will cool down on its way up to the surface and may solidify within the crust as plutonic rocks, resulting in intrusive landforms, or it may also form extrusive landforms when it thrusts its way upwards and cools on the surface.
The ancient people in Greeks believed that volcanic eruptions occurred when the god of the underworld, Lord Vulcan, stoked his furnace beneath the volcano, which is an island in Sicily.
But geologists have made it sure that it is activity is very closely related to the Crystal disturbance, particularly in those places which are classified as the zones of weakness due to Deep faulting or mountain folding.
The temperature below the surface of the Earth increases with increasing depth. The interior of the Earth is in a semi-molten state, comprising solid, liquid, and gaseous materials collectively known as magma. This magma is heavily loaded with gases such as hydrogen Sulphur dioxide, and carbon dioxide It also contains small amounts of Nitrogen, chlorine, and other volatile substances, which cause the temperature of the magma to increase further. The gases present in the magma enhance its movement capacity and also increase the rate of explosiveness of the Lava, which will be emitted through the surface of the crust.
The circum-Pacific region of the Earth is prone to earthquakes and also has the largest number of active volcanoes. This is basically due to the fact that this region is highly faulted.

Volcanoes erupt due to the extreme temperature inside Earth. This extreme heat melts the Rock inside the Earth and forms a thick liquid substance. The molten rock is not as dense as the surrounding rocks and does rise upward and collect in Chambers. Some of this molten rock is pushed outside from the cracks or fissures on the surface of Earth. This makes a Volcano erupt, and the thick molten Rock comes out. The thick, flowing substance that forms from the melting of Rock deep in the Earth’s crust is called Magma. Lava is the Magma that comes out during a volcanic eruption. A dormant volcano is a volcano that has not erupted recently but may erupt in the future. Mauna Loa is an active volcano and the largest volcano on Earth. The summit of the volcano is about 17 kilometres above its base.
