13. Geology
13.1 Plate Tectonics, Continental drift theory
Plate Tectonics & Continental Drift: How Earth's Surface Moves
You will discover how Earth's outer layer is broken into moving plates and how Alfred Wegener's continental drift theory changed the way scientists understand our planet.
What You'll Learn
You learn how tectonic plates move on the asthenosphere slowly.
You discover Wegener used fossils and rocks as drift evidence.
You explore convergent, divergent, and transform plate boundary types.
You understand convection currents drive all tectonic plate movement.
What You'll Practice
1
You will identify geological features formed at each boundary type.
2
You will match fossil and rock evidence to continental drift theory.
3
You will define key vocabulary like subduction and seafloor spreading.
Why This Matters
Understanding plate tectonics gives you the scientific tools to explain earthquakes, volcanoes, and mountain formation some of the most powerful forces shaping the world you live in.
