Question

which example best illustrates a method to show differences among earth’s layers?
○ carson models how the continental crust varies in thickness.
○ marisol records atmospheric and oceanic temperatures at several beaches.
○ eliza analyzes seismic wave activity from an earthquake using a computer model.
○ oscar determines the pressure at different depths of earth’s crust.

Explanation:

Seismic waves change speed and behavior as they pass through different Earth layers (crust, mantle, outer core, inner core) because each layer has distinct composition and physical properties. Analyzing this activity can map all Earth's layers, unlike the other options which only focus on the crust or non-layer atmospheric/oceanic data.

Answer:

Eliza analyzes seismic wave activity from an earthquake using a computer model.
