Question

Quizplus · Accepted Answer

The primary layers of the Earth, defined by their physical properties from shallowest to deepest, are the lithosphere (crust and uppermost mantle), asthenosphere (part of the upper mantle with different mechanical properties), mesosphere (stiffer part of the mantle beneath the asthenosphere), outer core (liquid), and inner core (solid).
