yers of the Earth
Cross-section illustration of a sphere resembling Earth with a wedge removed to reveal four concentric layers from outer to inner. Each layer is shown as a distinct band surrounding a small central core, with leader lines from each layer to labels. The outer surface shows continents; the interior layers are depicted with contrasting tones and textures.
Which layer of the Earth shown on the diagram is the hottest?
A crust
B mantle
C inner core
D outer core

Answer 1

C — inner core.
The inner core is the hottest part of Earth (temperatures around ~5,000–7,000 °C), hotter than the outer core, mantle, and crust.
