Study Notes
Plate Boundaries and Movements
- Plates at divergent boundaries move apart, resulting in the formation of new oceanic lithosphere.
- Convergent plate boundaries involve plates moving toward each other, often leading to seismic activity.
- At transform plate boundaries, plates slide past one another without significant vertical movement.
Earthquakes and Volcanic Activity
- Most earthquakes and volcanic eruptions occur at convergent and divergent plate boundaries due to the geological activity involved.
- Volcanoes in subduction zones typically form on the overriding plate and are located away from the convergent boundary, influenced by heat and pressure.
Specific Geological Features
- The East African Rift, a divergent plate boundary, is expected to eventually give rise to an ocean as the continent of Africa splits into two.
- Transform boundaries do not produce volcanoes as they do not alter pressure, temperature, or the composition of the mantle.
Tectonic Plate Overview
- Tectonic plates are located at Earth's surface and interact primarily at their boundaries, leading to various geological phenomena.
- The three main types of plate boundaries are divergent, convergent, and transform, each characterized by distinct movements and geological consequences.
Earthquake Patterns
- Earthquakes with a magnitude greater than 4.0 exhibit patterns that closely correlate with plate boundaries, highlighting the relationship between tectonic activity and seismic events.
