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 mineral content of rock core samples at different depths in Earth's crust.

The correct option is Oscar determines the mineral content of rock core samples at different depths in Earth's crust

Explanation:

We know that Earth layers are divided into different distances from its core. They vary from depth to depth inside the earths core. The layers of earth are basically formed by the types of rocks inside it. The very internal shape of earth contains molten rocks and the very outer layer called the crust has hard rocks so we can say that the types of rocks is responsible for the formation of earth's layers.
