Answer:
Johnny is correct.
Step-by-step explanation:
Volcanoes are openings in mountains present on the Earth's surface that expel gases, fire and lava. Volcanoes arise when so-called tectonic plates - which are part of the earth's crust - move toward each other and collide by moving the material present over them and leaving openings for deeper layers of the planet. Through these openings can come the magma present between the crust and the blanket - middle layer of the Earth.
According to this, we can say that Jhonny is correct.
