The phrases that are true of only the mantle are:
- has a tarry layer
- has a solid outer layer
The mantle is made of solid rock, but it also has a partially molten layer that can be described as "asthenosphere," which has some properties resembling a tarry consistency. It is not accurate to say it has a molten outer layer, as that would refer more specifically to the outer core. The mantle is generally described in terms of its upper and lower layers, rather than three distinct layers.
