Study Notes
Plate Tectonics
- The Ring of Fire accounts for 80% of Earth's volcanic and earthquake activity due to the convergence of multiple plate boundaries.
- Earthquakes and volcanoes occur at plate boundaries where there is a build-up of stress between plates.
Subduction
- Subduction occurs where oceanic and continental plates converge, with denser oceanic plates being pushed beneath the lighter continental plates.
- Subduction zones are characterized by deep-sea trenches and volcanic arcs.
Plate Boundaries
- Divergent plate boundaries are associated with mid-ocean ridges and the formation of new oceanic crust.
- Transform plate boundaries are associated with fault lines, such as the San Andreas Fault.
- Convergent plate boundaries can be either continental-continental or oceanic-continental, resulting in mountain building or subduction.
Rocks
- The three types of rocks are igneous, sedimentary, and metamorphic.
- Igneous rocks are formed through the cooling and solidification of magma or lava.
- Sedimentary rocks are formed through the compression and cementation of sediments.
- Metamorphic rocks are formed through the alteration of existing rocks under high heat and pressure.
Earth's Structure
- The lithosphere is the outermost solid layer of the Earth, broken into several large plates that move relative to each other.
- Convection occurs in the Earth's mantle, driving the movement of tectonic plates.
Continental Drift
- Alfred Wegener used fossil evidence, similarities in coastline shapes, and paleomagnetism to support his theory of continental drift.
Earth's Crust
- The Earth's crust is broken into several large plates that move relative to each other, resulting in geological activity at their boundaries.
