Question

starting at the earths surface (the crust, or lithosphere) and moving downwards to the center of the earth, what is the correct sequence for the layers of the earth?
lithosphere> asthenosphere> mantle> core
core> mantle> lithosphere> asthenosphere
mantle> asthenosphere> lithosphere > core

Explanation:

To determine the correct sequence of Earth's layers moving downward from the surface:

1. The lithosphere (includes the crust) is the outermost layer.
2. Below the lithosphere is the asthenosphere (part of the upper mantle, more ductile).
3. Next is the mantle (thick layer between crust and core).
4. The core (inner and outer) is at the center.

So the sequence is lithosphere > asthenosphere > mantle > core. The other options have incorrect orders (e.g., core or mantle first which is wrong as we start at the surface).

Answer:

A. lithosphere> asthenosphere> mantle> core
