Question

The inner core is solid, extremely hot and under immense pressure from all the rock above it. The outer core is molten, so it's liquid, and also very hot. This core extends 1,800 miles around from the center of the Earth.

The layer after the core is the mesosphere. This layer is mostly solid and extends outward another 1,500 miles. The asthenosphere is a thin layer, about 150 miles thick, at the border between the mantle and the crust. It is still very hot, and nearly (but not quite) a liquid. Because of this, pieces of the Earth's crust can move very slowly above it.
Which of the following is true about the Earth’s layers?
A: The asthenosphere is the thickest of Earth’s layers.
B: All of the layers are liquid and extremely hot.
C: There is little to no pressure on the solid core.
D: The Earth’s core has two different parts.

Answer 1

Answer: D: The Earth’s core has two different parts.

Step-by-step explanation:

the earths core is split up into a solid and a liquid part the solid part is solid because of all the pressure of the other layers
