How does the global pattern of earthquake locations help geologists understand the Earth's structure?

It shows where the Earth's magnetic field is strongest.

It reveals the outlines of tectonic plates by forming distinct lines of activity.

It indicates the deepest parts of the ocean floor.

It helps predict the timing of future volcanic eruptions.

What is the primary reason why earthquakes are concentrated in long, narrow zones that define plate boundaries?

These zones have weaker rock that is more prone to shaking.

The Earth's crust is thinnest in these specific locations.

These are the areas where separate crustal plates interact and move against each other.

The gravitational pull from the sun and moon is focused on these lines.

The crust is a single, unbroken shell.

The crust is composed of separate, interacting pieces.

The crust is uniformly thick across the globe.

The crust is rapidly cooling and shrinking.

They have found a new volcanic hotspot.

The Earth's core has changed its rotation.

They have identified a previously unmapped plate boundary.

The area is experiencing a change in climate.
