Delve into plate tectonics and its effects including divergent boundaries forming mid-ocean ridges, convergent boundaries creating mountains and volcanoes, transform boundaries like the San Andreas Fault causing earthquakes, and evidence for plate movement through rock layers and fossils. This interactive journey includes insights on the formation of new rocks, tectonic features like trenches, and the dynamics of Earth's shifting plates.
E N D
Divergent Boundaries • Plates moving AWAY from each other.
Landforms and effects • Mid-Ocean ridges • Earthquakes • New rock forming on plates (Africa, Iceland)
Convergent Boundaries • When plates come together or collide
Features • Trenches (Subduction) • Volcanoes • Mountains • Earthquakes
Transform Boundaries • Plates SLIDE past each other, moving in opposite directions.
Results • Earthquakes
Evidence for Plate Movement • Shape of continents match up
Fossil record • Rock layers
Magnetic stripes on the sea floor • Rock ages of the sea floor
