* Average density: Approximately 4.5 g/cm³
* Upper mantle: Ranges from 3.3 g/cm³ to 4.4 g/cm³
* Lower mantle: Ranges from 4.4 g/cm³ to 5.6 g/cm³
The density of the mantle increases with depth due to:
* Pressure: The immense pressure at deeper levels compresses the minerals, making them denser.
* Composition: The upper mantle is primarily composed of peridotite, which is less dense than the minerals found in the lower mantle, like bridgmanite and ferropericlase.
It's important to note that these are approximate values and the exact density can vary depending on the specific location and geological conditions.
