2. 7.2 Volcanoes

3. Volcanoes
Volcano-a vent or fissure in the Earth’s surface through which magma and gases are expelled
Magma chamber-the body of molten rock that feeds a volcano
Volcanic Bomb-Magma that hardens in midair
Pyroclastic flow-glowing cloud of volcanic material that can move faster than 200km/h

4. Shield volcano- a volcano built form layers of released from repeated nonexplosive eruptions

5. Composite volcano- form from alternating explosive and nonexplosive eruptions

6. Cinder cone- volcanoes made of layers of pyroclastic materials from moderately explosive materials

7. Volcanic Landforms
Hotspot- a volcanically active area of Earth’s surface far from a tectonic plate boundary

8. Riftzone- an area of deep cracks that form between two tectonic plates that are pulling away from each other
Lavaplateau- a wide, flat landform that results from repeated nonexplosive eruptions of the lava that spread over a large area

9. Crater- a funnel-shaped pit near the top of the central vent of a volcano
Caldera- a large, semi circular depression that forms when the magma chamber below a volcano partially empties and causes the ground above to sink
