Question

1. the correct vertical zonation of earth above the core is

(a) asthenosphere-mantle-soil-lithosphere.
(b) asthenosphere-lithosphere-mantle-soil.
(c) mantle-asthenosphere-lithosphere-soil.
(d) mantle-lithosphere-soil-asthenosphere.

Explanation:

To determine the correct vertical zonation of Earth above the core, we recall the layers: The core is surrounded by the mantle. Above the mantle is the asthenosphere (a part of the upper mantle with plastic behavior), then the lithosphere (which includes the crust and upper rigid mantle), and finally the soil (part of the Earth's surface/geosphere - biosphere interface). So the order from core - outward (above core) is mantle → asthenosphere → lithosphere → soil.

Answer:

(c) mantle - asthenosphere - lithosphere - soil
