Based on the values in the provided table, we’ll analyze the densities in each layer of the Earth to determine where the rocks are the most dense.

1. Crust:
- Minimum density: 2.2 g/cm³
- Maximum density: 2.9 g/cm³

2. Upper Mantle:
- Minimum density: 3.4 g/cm³
- Maximum density: 4.4 g/cm³

3. Lower Mantle:
- Minimum density: 4.4 g/cm³
- Maximum density: 5.6 g/cm³

4. Core:
- The specific densities for the core are not provided in this table, so we will focus on the crust and mantle layers provided.

From the data:

- For the crust, the density ranges from 2.2 to 2.9 g/cm³.
- For the upper mantle, the density ranges from 3.4 to 4.4 g/cm³.
- For the lower mantle, the density ranges from 4.4 to 5.6 g/cm³.

We need to determine which layer contains the rocks with the highest densities. We see that the:

- Crust has the lowest density range (2.2-2.9 g/cm³).
- Upper mantle has a higher density range (3.4-4.4 g/cm³) than the crust.
- Lower mantle has the highest density range (4.4-5.6 g/cm³) compared to both the crust and the upper mantle.

Therefore, based on the provided densities, we conclude that the rocks in the lower mantle are the most dense.

Conclusion: The rocks in the lower mantle are the most dense.
