Plate Tectonics — what causes surface features?
Movement of Earth's lithospheric plates.
Earth's Layers — composition?
Crust, mantle, core with distinct properties.
Historical Development — key evidence?
Seafloor spreading and paleomagnetic data.
Tectonic Plates — definition?
Large, rigid Earth's lithosphere pieces that move.
Lithosphere vs Asthenosphere — difference?
Lithosphere is rigid; asthenosphere semi-fluid.
Seafloor Spreading — process?
New crust forms at divergent boundaries.
Subduction Zone — role?
One plate sinks beneath another.
Plate Boundary Types — examples?
Divergent, convergent, transform.
Earthquake Causes — main mechanism?
Plate movements along boundaries.
Seismic Scale — name?
Richter scale.
