Study Notes
Tectonic Plates
- Earth's outer layer is broken into massive, moving pieces called tectonic plates.
- Plates interact at their boundaries, causing earthquakes, volcanoes, and mountain formation.
Continental Drift
- The theory that continents have moved over time.
- Proposed by Alfred Wegener in the early 20th century.
- Evidence includes matching coastlines, fossil distribution, and rock formations across continents.
Layers of the Earth
- Crust: The thin, outermost layer, composed of solid rock.
- Mantle: The thickest layer, composed of hot, dense rock that behaves like a very viscous fluid.
- Outer core: Liquid iron and nickel, responsible for Earth's magnetic field.
- Inner core: Solid iron and nickel, incredibly hot and under immense pressure.
Mantle Convection
- Heat from Earth's core creates convection currents in the mantle.
- Hotter, less dense material rises, while cooler, denser material sinks.
- This movement drives tectonic plate motion.
