15.2 Plate Tectonics, Global patterns
Plate Tectonics: Uncovering the Forces That Shape Our Planet
Discover how Earth's moving tectonic plates create mountains, ocean trenches, volcanoes, and earthquakes in patterns that span the entire globe.
What You'll Learn
Tectonic plates move slowly over the semi-fluid asthenosphere layer.
Convergent, divergent, and transform boundaries create distinct geological features.
Paleomagnetism and seafloor spreading provide strong evidence for plate tectonics.
The Ring of Fire marks intense volcanic and seismic activity worldwide.
What You'll Practice
1
Students calculate seafloor spreading rates using distance and time data.
2
Questions test knowledge of boundary types and their geological features.
3
Learners identify evidence supporting continental drift and plate tectonics.
Why This Matters
Plate tectonics explains the global distribution of earthquakes, volcanoes, and mountain ranges, making it fundamental to understanding Earth's dynamic systems and natural hazards.
