Vents are the fissures present on the surface of the earth (both at the land surface and sea bottom) that are produced when the hot gaseous materials including both liquid and gases are released into the atmosphere. For example, the hydrothermal vents located at the seafloor through which magma and hydrothermal gases are released.
The volcanoes are the distinct geological features that are formed on the earth's surface due to the rising up of magma, and it reaches the surface, it forms vents, through which the lava and the volcanic gases are released.
A volcanoes that form after the occurrence of the overlying crust is ruptured by the heated gases and forms the resulting magma and thus magma when escaping leads to the flowing of the lava and the heat to reach the surface of the earth.
