Which statement is supported by the information in the table?

A. As depth increases, the density of the layers increases.

B. As depth increases, the density of the layers decreases.

C. As depth increases, the thickness of the layers increases.

D. As depth increases, the thickness of the layers decreases.

Let's analyze the given information step-by-step to determine which statement is supported by the data in the table.

First, we need to look at the densities of the different layers to see how density changes with depth. The table provides the following data:

1. Crust
- Thickness: 30 km
- Top Density: 2.2 g/cm³
- Bottom Density: 2.9 g/cm³

2. Upper Mantle
- Thickness: 720 km
- Top Density: 3.4 g/cm³
- Bottom Density: 4.4 g/cm³

3. Lower Mantle
- Thickness: 2,171 km
- Top Density: 4.4 g/cm³
- Bottom Density: 5.6 g/cm³

4. Outer Core
- Thickness: 2,259 km
- Top Density: 9.9 g/cm³
- Bottom Density: 12.2 g/cm³

Next, we need to assess how the density changes from one layer to the next:

- From the Crust to the Upper Mantle:
- Crust Bottom Density: 2.9 g/cm³
- Upper Mantle Top Density: 3.4 g/cm³
- Increase in density: Yes (2.9 < 3.4)

- From the Upper Mantle to the Lower Mantle:
- Upper Mantle Bottom Density: 4.4 g/cm³
- Lower Mantle Top Density: 4.4 g/cm³
- Increase in density: No change (4.4 = 4.4)

- From the Lower Mantle to the Outer Core:
- Lower Mantle Bottom Density: 5.6 g/cm³
- Outer Core Top Density: 9.9 g/cm³
- Increase in density: Yes (5.6 < 9.9)

Since there is a consistent increase or maintenance of density moving from one layer to the next (except for no change between the Upper Mantle and Lower Mantle top density), we can conclude that overall, the density of Earth's layers generally increases as depth increases.

Hence, the correct statement supported by the information in the table is:
- As depth increases, the density of the layers increases.
