Answer:
When cracks occur on the earth's surface and these cracks separate, the appearance of openings in the soil occurs. These openings can be called volcanic fissures which is the volcano.
Step-by-step explanation:
Volcanoes are openings in the ground, through which hot, melting rocks and gases emerge on the surface. They are terrible indications of great heat and pressure in the deeper layers of the Earth, that is, of the turbulent forces that move there.
Volcanoes They manifest at points where the crust is weaker, especially where two plates (sections of the earth's crust) meet or separate. There, the pressure can force molten rock and other mantle substances to emerge to the surface of the Earth.
When there are volcanic eruptions, molten rock, called magma, is ejected, which forms at great depths. On the surface, magma may explode in the air in fragments, ranging from fine, hot dust, to large stones called volcanic bombs, or it may spill into lava streams.
