Uncover the dynamic process of plate tectonics, shaping continents and triggering natural phenomena like earthquakes and volcanic eruptions. Learn about divergent, convergent, and transform boundaries, as well as the formation of hotspot volcanoes. Explore the evidence behind Alfred Wegener's continental drift theory, and witness the impact of plate movements on Earth's geology throughout history. Also, dive into the significance of regions like the Pacific Ring of Fire in understanding our planet's ever-changing surface.

Large moving slabs of rock slide slowly over a layer of the mantle Plate Tectonics
Alfred Wegener’s Evidence: The presence of fossils only over small areas of now separate continents
3 Types of Plate Boundaries • Divergence • Convergence • Transformal
Process where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge Sea-Floor Spreading
Forms mountains, e.g. European Alps, Himalayas CONVERGENCE
Transformal No mountains are created
What are Hotspot Volcanoes? • Hot mantle breaches the surface in the middle of a tectonic plate The Hawaiian island chain are examples of hotspot volcanoes.
