Question

which example best illustrates a method to show differences among earths 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 earths crust.

Explanation:

Seismic waves change speed and direction (refract or reflect) when they encounter boundaries between different Earth layers. Analyzing seismic wave activity (like Eliza does) helps show differences among Earth's layers. Carson's focus is only on continental crust thickness (not all layers). Marisol's work is about atmospheric and oceanic temps (not Earth's internal layers). Oscar's is about pressure in Earth's crust (not all layers).

Answer:

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