Answer 1

The correct items to write sentences explaining why the earthquake risk is so high on the West Coast by California (CA) and Alaska (AK) are "transform boundary" and "convergent boundary."

1. The high earthquake risk on the West Coast by California and Alaska is mainly attributed to the transform boundary. This type of boundary occurs when tectonic plates slide horizontally past each other, causing significant friction and pressure buildup over time. When this built-up energy is released suddenly, it leads to frequent and often powerful earthquakes.

2. Additionally, the convergent boundary also contributes to the high earthquake risk in this region. At a convergent boundary, two tectonic plates collide and force one plate to subduct beneath the other. This subduction process creates intense pressure and stress, eventually resulting in seismic activity and the formation of explosive volcanoes, commonly seen in the Cascade Range of California and Alaska.
