A volcano is a unique mountain or a hill with a crater or vent through which lava, rock fragments, hot vapor, and gas are being or have already been propelled from the earth’s crust. This quiz on volcanoes explains what most shield volcanoes have grown from the ocean floor to form, what occurs when the temperature of lava increases, and an example of a composite volcano. This quiz is overflowing with information; give it a shot.
