Study Notes
Lesson 4 - What Are Volcanoes?
- Lesson objective: Define a volcano and identify key features. Describe 3 stages of volcanoes (active, dormant, extinct). Describe volcano structure and types (composite, shield, cinder cone). Explain volcano distribution and formation (constructive, destructive, hotspots). Draw volcano structure, and suggest why volcanoes are dangerous.
- Key Vocabulary: Constructive, Destructive, Hotspot, Lava, Magma, Vent, Crater, Magma Chamber.
- Volcano Definition: A volcano is a surface geological landform resulting from the extrusion of magma from underground into Earth's crust, and the eruption of that magma onto the Earth's surface through a vent.
- Volcano Features: Crater, secondary cone, secondary vent, layers of lava and ash, main vent, ash, steam, gas, volcanic bombs, lava flow, magma chamber.
- Volcanic Hazards: Lava flows, lahars or mud flows, jokulhlaups, volcanic bombs, ash clouds/ash fall, volcanic gases, pyroclastic flows.
- Volcanic Eruptions: Example of Mount Vesuvius eruption in 79 BCE and its impact on the city of Pompeii.
- Volcano Locations: Volcanoes are generally found near tectonic plate boundaries, with about 90% of Earth's earthquakes and 75% of volcanoes located along the "Ring of Fire" in the Pacific Ocean. Some also occur away from plate boundaries.
- Types of Volcanoes: Composite volcanoes have steep slopes and thick, sticky lava. Shield volcanoes have gentle slopes and fluid lava. Cinder cone volcanoes are made up of layers of cinders and have a bowl-shaped crater at the top.
- Volcano Formation: Volcanoes are formed by constructive plate boundaries, destructive plate boundaries, and hotspots. At constructive boundaries, plates move apart, allowing magma to rise and create new crust on the ocean floor. At destructive boundaries, denser oceanic crust is subducted beneath less dense continental crust, causing melting and magma formation. Hotspots are areas where magma rises through cracks in Earth's crust, unrelated to plate boundaries.
- Volcano Stages: Active volcanoes have erupted recently and might erupt again. Dormant volcanoes haven't erupted for a while but could erupt in the future. Extinct volcanoes haven't erupted for thousands of years and are not expected to erupt again.
