Question

comparing the mantle and core
which phrases are true of only the mantle? check all that apply.
made of three layers
has a tarry layer
made of two layers
has a molten outer layer
has a solid outer layer

Explanation:

The Earth's mantle is made of two layers - the upper mantle and lower mantle. It has a tar - like (viscous) layer called the asthenosphere in the upper mantle. The core has a molten outer layer and a solid inner layer, and is not made of two layers like the mantle. The Earth's crust, mantle and core together are three - layer structure of the Earth, not a property of the mantle alone.

Answer:

has a tarry layer
made of two layers
