Study Notes
Tsunamis and Earthquakes
- The primary cause of a tsunami is the displacement of a large volume of water, usually as a result of an earthquake or landslide.
- The measure of an earthquake's magnitude is its size or strength, usually measured using the moment magnitude scale.
Continental Drift
- Wegener's continental drift hypothesis states that the continents were once joined together in a single supercontinent, Pangaea, which broke apart over time.
- Fossils of the same age and species found on different continents, and the matching of continental coastlines, support Wegener's continental drift hypothesis.
Earth's Structure
- The Earth's thin, rocky outer layer is called the lithosphere.
Earthquakes and Landslides
- Violent shaking from an earthquake can cause landslides on slopes.
Plate Tectonics
- When divergence happens within the oceanic lithosphere, new crust is created as magma rises to fill the gap.
- When one oceanic plate is forced beneath another plate, a trench forms.
- According to the theory of plate tectonics, the Earth's lithosphere is divided into plates.
- Thermal convection in the Earth's mantle, driven by heat from the Earth's core, causes plate motion.
Volcanoes and Magma
- Magma forms when solid rock in the crust and upper mantle is heated and melts.
- The solid particles produced in volcanic eruptions are called pyroclasts.
- The broad, slightly dome-shaped volcanoes of Hawaii are examples of shield volcanoes.
Mountains and Deformation
- Brittle deformation is generally seen on the Earth's surface, where rocks are broken and faulted.
- Folded mountains, such as the Himalayas, are an example of the process of orogenesis that occurs at convergent boundaries.
