Question

which phrase describes a feature of an earthquake’s epicenter?
○ starting point of an earthquake
○ place around the center of an earthquake
○ region directly above the focus
○ point about 100 kilometers deep in the lithosphere

Explanation:

The focus is the underground starting point of an earthquake. The epicenter is the point on Earth's surface that lies directly above this underground focus. The first option describes the focus, not the epicenter. The second option is a vague, incorrect description. The fourth option refers to a deep underground point, which is characteristic of a focus (not the surface-based epicenter).

Answer:

region directly above the focus
