Summary:
- The theory of plate tectonics is what brings together continental drift and seafloor spreading.
- There are three types of plate boundaries since there are three ways that plates can meet.
- The features seen at a plate boundary are determined by the direction of plate motion and by the type of crust found at the boundary.
- Most geological activity takes place at plate boundaries.
- It explains why volcanoes, earthquakes, mountain ranges, ore deposits, and other features are located.
- It is the key that unlocks many of the mysteries of our amazing planet.
