Answer:
A volcano is formed when hot molten rock, ash and gases escape from an opening in the Earth's surface. The molten rock and ash solidify as they cool, forming the distinctive volcano shape shown here. As a volcano erupts, it spills lava that flows downslope. Hot ash and gases are thrown into the air.
Three types of volcanoes are:
cinder cones (also called spatter cones).
composite volcanoes (also called stratovolcanoes)
shield volcanoes.
