the body of molten rock that feeds a volcano

an opening at the surface of the Earth through which volcanic material passes

a vent or fissure in the Earth's surface through which magma and gases are expelled

a large, semicircular depression that forms when the magma chamber below a volcano partially empties and causes the ground above to sink

a funnel-shaped pit near the top of the central vent of a volcano

a wide, flat landform that results from repeated nonexplosive eruptions of lava that spread over a large area

an area of deep cracks that forms between two tectonic plates that are pulling away from each other

a volcanically active area of Earth's surface far from a tectonic plate boundary

the way lava flows

lava that explodes out of a volcano and hardens when it comes in contact with the air

clouds of ash, dust and gases that flows from a volcano
