Final answer:
Plate movement direction can change depending on the location and type of plate boundary. Yellowstone and Anahim hotspots have different rates of plate motion. Yellowstone is in a divergent boundary and Anahim is in a hotspot.
Step-by-step explanation:
The direction of plate movement can change depending on the location and type of plate boundary. The rates of plate motion for Yellowstone and Anahim hotspots are different. Yellowstone is located in a divergent boundary, where plates are moving away from each other.
Anahim is located in a hotspot, where a plume of hot material rises from deep within the Earth's mantle. These different types of plate boundaries and geological processes result in different rates and directions of plate motion.
