Study Notes
Geologic History and Plate Tectonics
Effects of Plate Tectonics
- Earthquakes
- Land slides
- Sea level rise
- Volcanic events
Unique Locations
- You can stand with one foot in Europe and the other foot in North America in Iceland
- Endangered cities: Tokyo, San Francisco
Engine of Plate Tectonics
- Convection currents drive plate tectonics
Earth's Crust
- If the Earth was the size of a basketball, the solid crust would be as thick as a piece of paper
Heat Source
- Iron and nickel, along with radioactive materials, keep the Earth's core and mantle at high temperatures
Himalayan Mountains
- The Indian plate collided with the Asian plate to form the Himalayan mountains, placing ocean fossils near the top
Ring of Fire
- Located in the Pacific Ocean
- Features: volcanos
- Events: earthquakes
Loudest Sound
- Possible source: volcanic eruption
Natural Bombs
- Volcanos, waiting to explode
- America's natural time bomb: Yellowstone National Park's Supervolcano
- Explosion of Yellowstone Park's Supervolcano will have a devastating effect on the Earth and its inhabitants
Earth's Plates
- Plates move with convection currents
- 20 plates on Earth, 7 main plates
- Plates float over liquid mantle and convection currents move them
Ocean Expansion
- Atlantic Ocean is growing wider
- Pacific Ocean is shrinking in width
Lava and Magma
- Lava: molten rock that emerges on the Earth's surface
- Magma: molten rock beneath the Earth's surface
Future Time Bombs
- MegaThrust: shaking of the Earth
