Answer:
Its when unnatural things, turn natural things irregularly hot or cold.
Mt. Vesuvius is A VOLCANIC MOUNTAIN.
It was famously known for causing the fires of Pompeii and killing millions of people.
Mt. Vesuvius, a cone-shaped mountain is part of the Campainian Volcanic Arc. It has erupted 30 times as recorded by scientists. It is currently considered as one of the top ten most dangerous volcanoes of the world.
In which plate boundary two plates move towards each other and collide called convergent plate boundary. And causes devastation. E.g. Earthquake, Vulcanicity. In which plate boundary two plates move in opposite direction and do not collide called divergent plate boundary. Mountain building is the result of this type of plate boundary's action. In transform fault both the plates slide each other and causes fault in the sea floor.
Explanation:
Plate is a rigid and solid crustal block which is mobile in character and found in the asthenosphere in the upper mantle. It prevails in semi liquid and viscous condition where plates move easily. There are seven major plates and twenty minor plates. Plates are of two types. Continental plate and oceanic plate.
Where two plates collide with each other that area is known as plate boundary and the edge of plate is known as plate margin. Plate boundary is of three types: Convergent, divergent and transform plate boundary. These are also known as constructive, destructive and neutral plate boundaries.
Volcanoes play an important role in creating land since they are the sources of magma, which once above ground normally cools to create new land. In the ocean, this land normally forms at divergent and convergent boundaries or hot spots. At divergent boundaries (where two plates move apart), magma constantly erupts along a trench deep below the ocean's surface. This magma rarely piles upward and instead is pushed to both sides of the trench. This is how new seafloor forms. Convergent boundaries can create island arcs like Indonesia as magma erupts bit by bit. Hot spots occur in the middle of plates. They are instances where the mantle pierces through the crust and begins to erupt directly onto to seafloor. Over time, these eruptions will pile up and create underwater volcanoes until they potentially make it above sea level, thereby forming an island. This is how Hawaii was and continues to be formed.
