Look at the model below. What relationship do you see between the temperature (°C) and the depth (km)?

• As the depth increases, the temperature first increases and then decreases.

• As the depth increases, the temperature increases.

• As the depth increases, the temperature decreases.

• As the depth increases, the temperature stays the same.
