Study Notes
- Plate Tectonics exam: Name and test date
- Continental Drift: Theory explaining the movement of continents
- Ridge: Underwater mountain ranges formed by volcanic activity when plates move apart
- Pangaea: Ancient supercontinent that existed about 335 million years ago
- Lithosphere: Outer layer of the Earth, solid and brittle, divided into tectonic plates
- Lithosphere density: Lighter than the asthenosphere, allowing plates to move
- Seismic waves: Waves generated by earthquakes or volcanic eruptions, traveling through the Earth
- Ring of Fire: Pacific Ocean rim area with frequent earthquakes, volcanic eruptions, and tsunamis
- Earth's crust: Made up of many pieces called tectonic plates
- Plates move towards each other, one sinks under the other: Forms a subduction zone, creating volcanic activity
- Person studying the solid and liquid matter of the Earth: Geologist
- Lithospheric plates moving, causing: Volcanic eruptions, tsunamis, and earthquakes
- Labeled diagram: Tsunami: Series of large ocean waves; More likely in countries near the Pacific Ocean: Pacific Ring of Fire; Caused by earthquakes or volcanic eruptions
- After an earthquake, possible geological events: Landslides, liquefaction, volcanic eruptions
- Alfred Wegener: German meteorologist who proposed the theory of Pangaea in 1912
- Evidence supporting Pangaea theory: Fossil distribution, coastline shapes, and geological structures
- P waves: Primary seismic waves, move faster, compressional waves
- S waves: Secondary seismic waves, slower, shear waves
- Seismic waves: Recorded using seismographs to measure earth's internal activity.
- Tsunami: Short for "harbor wave," a series of large ocean waves often caused by earthquakes or volcanic eruptions.
- Countries more likely to have a tsunami: Pacific rim countries, such as Japan, Indonesia, and Chile.
- More likely due to: Proximity to the Pacific Ocean and the Ring of Fire, where earthquakes and volcanic eruptions are frequent.
- After an earthquake, possible geological events: Landslides, liquefaction, and volcanic eruptions.
