Answer:
Volcanoes can be described by their shape or type - shield or composite.
Step-by-step explanation:
Volcanoes have distinctive features:
magma chamber - this is where the molten rock is stored beneath the ground
main vent - this is the channel through which magma travels to reach the Earth's surface
secondary vent - some magma may escape through the side of the volcano, particularly if the main vent becomes blocked
crater - this is found at the top of the volcano, where the magma erupts from
