Why would the seismic activity density of the year for Alaska be smaller than for California if Alaska had more earthquakes?

Seismic activity density compares the number of earthquakes with the area over which they occur. Alaska can have more earthquakes overall but a lower density if its land area is larger, because those earthquakes are spread across more space. Therefore, the correct choice is “Alaska has more land area than California.”
